Castanea, Tournefort. The ancient classical name derived either from Castanis, a town in Thessaly, or one in Pontius, as historians disagree in regard to its derivation. The genus belongs to the order CupuliferÆ.

Male flowers irregularly clustered in long, naked, cylindrical catkins from the axils of the leaves and on the new shoots of the season. Calyx five or six parted; stamens or pollen-bearing organs seven to fifteen; anther two-celled. On old, mature trees, the male catkins are usually crowded near the end of the short new twigs, as shown in Fig. 12, the terminal one productive; but on young thrifty trees, wide apart. Female flowers always on and near the base of a late-developed male catkin, sometimes two or three together,—or even six or eight on the chinquapins,—oval or ovoid, scaly, prickly, two- to four-valved involucre or bur; calyx usually with a four- to six-lobed border crowning the three- to seven-celled ovary; stigmas bristle-shaped, and as many in number as there are cells in the ovary. Shell of the nut leathery, not brittle, ovoid, two or more together in the larger species, in others solitary, or only one in a bur. Kernel very thick, fleshy, and somewhat plaited, sweet and edible.

Both male and female flowers appear late in spring, the males usually exceedingly so, exhaling a slightly nauseating odor. The productive male catkins appear the latest, their base becoming the rachis or stalk supporting the burs, this rather anomalous arrangement appearing to be a natural provision to secure fertilization in case the earlier catkins failed.

The genus Castanea, as now restricted, contains shrubs and large trees, with simple, alternate deciduous leaves, coarsely serrate, with pointed spiny teeth. Indigenous, and widely distributed over northern Africa, southern Europe, Asia and the eastern half of the United States.

The common English name of this nut is supposed to be derived from the Anglo-Saxon cystel, chestnut, and cyst-beam or cisten-beam, chestnut tree; Old English, chastein or chesten; Old German, chestinna or kestinna; Modern German, kestene or kastanie; French, castaigne or chataigne; Provencal, castanha; Spanish, castana; Italian, castagna, from the Latin castanea.

History of the Chestnut.—The so-called European chestnut is supposed to be indigenous to Asia Minor, Armenia, Caucasus and northern Africa, and from these countries it was introduced and became naturalized throughout the greater part of temperate Europe, where it has been cultivated from time immemorial. The Romans are supposed to have distributed it northward through France and Great Britain, and in the latter country there were trees centuries ago of such large size that many of the early English authors claimed this tree was indigenous. But in the absence of any natural forests of chestnut, the claim had to be abandoned. In parts of France, Italy and Spain, the chestnut has become thoroughly naturalized and, as we may say, run wild, but as one of the early investigators says, in speaking of the abundance of old chestnut trees on the Apennines, they are generally scattered over the surface like trees on a well-arranged lawn, and not crowded and massed, as they would be in a state of nature or in a forest. On the south side of the Alps the trees grow up to an altitude of twenty-five hundred feet, and on the Pyrenees some two or three hundred feet higher.

There are old trees of immense size almost everywhere in the milder regions of Europe, and the celebrated monarchs of Etna have been many times described by travelers. The largest measure one hundred and eighty feet in circumference near the root. All the early Roman writers who have anything to say about rural affairs, mention the chestnut as one of their valuable trees, producing nuts used for various purposes. Pliny enumerates eight varieties, but Columella appears to place more value upon the timber, especially the sprouts, for stakes, than he does on the nuts. But long before the Romans began to cultivate the chestnut, the Greeks held it in high esteem under the name of Sardianos Balanos or Sardis nut, and still later it was called Dios Balanos Lopimon.

The European chestnut has been so frequently and extensively referred to by ancient and modern authors that it would not be at all difficult to fill a large volume with brief extracts from their works, but my aim is not so much to show what has been done with this nut in other countries as what we may do with it here. All nations who have any experience with it admit its value as food for many wild and domesticated animals, as well as for the human race, and we know, from our long experience with the native species, that it is highly esteemed wherever known, although it must be admitted that our sparse population and the abundance of other kinds of food, have tended to make us careless and neglectful of the indigenous chestnut.

It may be well, before dismissing this brief history of the chestnut, to add that while nearly all the ancient authors, in referring to it, employed its present scientific name of Castanea, still, when botanists first attempted what has since been recognized as the scientific classification of plants, many of them placed the chestnut in the same genus as the beech, retaining the generic name of Fagus for both.

LinnÆus, in his Systema NaturÆ, 1766, Vol. II, p. 630, describes two species of the chestnut and one of beech in the genus Fagus, although Tournefort, in his "History of Plants Growing About Paris," published seventy years before that of LinnÆus, had recognized the distinctive characteristics of these two groups of nut trees, and he adopted the present name of Castanea for the generic name of the chestnut, and Fagus for that of the beech. But nearly all of the English and earlier American botanists adopted and followed LinnÆus in his classification, ignoring the works of the earlier as well as contemporaneous continental botanists. I merely refer to this matter of botanical nomenclature because some of my readers may have occasion to consult the earlier authors who describe American plants, as, for instance, such works as John Clayton's "Flora of Virginia," 1739, Thomas Walter's "Flora Caroliniana," 1787, or Humphrey Marshall's "American Grove," 1785. In all of these, and others, the chestnut is described as a species of beech (Fagus).

Propagation of the Chestnut.—The usual mode of propagating the chestnut is from seed, when trees are wanted for general planting or for stocks upon which to graft improved and rare varieties. Under some conditions and circumstances, it is best to plant the nuts soon after they are ripe in autumn, and this appears to be the most natural method; in fact, it is the way in which forests have been produced and are constantly renewed and perpetuated, when man does not interfere to prevent it. But nature is in no hurry in such matters, while man always is, because his time is limited; consequently, in our attempts at the multiplication and cultivation of plants we aim to save both time and material, therefore cannot afford to adopt nature's slow and wasteful processes.

The principal objection to planting chestnuts in the fall is the danger of having them destroyed by vermin, which abound almost everywhere. There is also danger of the nuts sprouting prematurely in the autumn, and of the young growth being killed by cold or by excessive moisture during late fall rains. But these natural enemies and obstacles prevent an excess in number and the overcrowding of trees in our forests. It is, no doubt, possible and practicable to smear the nuts with poisonous substances, or those sufficiently offensive to prevent the depredations of vermin, but taking all things into consideration, I am decidedly in favor of preserving the nuts in bulk and in a dormant state until the season arrives for insuring a rapid and continuous growth, and then planting them. To do this in our cold northern climate, as well as in the South, requires more care and attention with chestnuts than with the harder-shelled kinds, like the walnut and hickory nut. As a rule, it may be said that all the hardy kinds of nuts sprout at a rather low temperature and a few degrees above the freezing point, and for this reason it is well to select as cool a spot in the open ground as possible for their winter quarters, and then examine them as early as can be done conveniently in the spring.

In this matter of manipulating and preserving chestnuts for planting, as well as what follows in regard to transplanting, pruning and grafting, I shall give my own practice, with results; and while it may differ from that of other propagators, it is one evolved from long experience, many successes, and a few failures.

Gathering and Assorting Nuts.—When the nuts begin to ripen and fall, gather as soon as possible, and if the trees are on your own grounds and will admit of such an operation, thrash them and secure the entire crop at once. The object of this early gathering is to collect the false and weevil-infested specimens and destroy them. But in whatever way the nuts are collected, they should be stored in the shade and in shallow boxes, or spread out on a tight floor; but the better way would be on screens over a floor, and then when the grubs worked their way downward through the nuts and screen, they would fall upon the floor, from which they could be taken up and burned or otherwise destroyed. The nuts, while on the screen or other receptacle, should be stirred over daily for two or three weeks, and by that time they will be in good condition for either planting or packing away for the winter. But before finally disposing of the nuts in either way, they should be carefully looked over, and every shrunken specimen, as well as all with punctured shells from which the grubs have escaped, removed from among the sound stock, because these damaged nuts are not only useless, but are very likely to decay and affect all with which they come in contact. It is not to be expected that by such means or handling we can get rid of all the grubs enclosed in the nuts when gathered, for there will always be a few not more than half grown at the time, and these will remain hidden in the nuts until midwinter, or later, but the greater part of the brood will reach maturity within two or three weeks after the nuts are ripe. Of course, what is said here about chestnut weevils is only applicable to chestnuts grown in this country, but all species and varieties, when planted here, are subject to the attacks of this pest—at least, everywhere in the Eastern and Southern States.

Having assorted the nuts carefully, the sound ones should be reserved for planting; these should be mixed with or stratified with moist, sharp sand, and stored in boxes of convenient size for handling and examination, whenever this is required. In preparing the boxes, bore a number of small holes through the bottom, and over each of these lay a piece of a broken flower-pot, brick or stone, then cover the bottom one inch deep with the moist sand, and on this place a single layer of nuts, then fill in all interstices with sand, and also use enough more to fairly cover the layer; and proceed in this way until all the nuts are disposed of or the box is full, covering the top layer one or two inches deep, because the sand will settle some after the work seems complete. The boxes may be covered with fine wire netting or with narrow strips of boards, fitting these so that mice cannot get in, but should not be air-tight. They may then be buried in the open ground, selecting some knoll or dry spot for this purpose, for the nuts should not be placed where they will be submerged, or even be water-soaked, at any time during the fall, winter or early spring. If no such spot is conveniently near, then set the boxes on the top of the ground, and on the north side of some building or in the shade of an evergreen tree, and bank over with soil, covering the boxes a foot deep. If the spot selected is under the eaves of a building, place boards over the heap of soil, to carry off the water, for the object is to keep the nuts moderately moist, cool, and where they will not be subjected to frequent changes of temperature. In our Northern States the nuts, under such conditions, usually become frozen during the coldest weather, but this does not injure them if the sand is moist and they remain frozen, as there will be no danger of germination; while if kept too warm, they may start to grow before the seedbed is ready, in spring, for their reception. I have tried keeping the nuts mixed with sand in a cool cellar, also in outbuildings, but have not found any other place so certain as pits in the open ground.

Seedbed and Soil.—It is well to have the seedbed prepared the previous autumn, but it is not absolutely necessary. The soil for the bed should be light, either sandy or loamy, and if not rich, made so by adding very old and fine stable manure, or leaf mold from the forest—I prefer the latter, as it is the most natural for all kinds of seedling nut trees. Whatever fertilizing materials are used, they should be placed on or near the surface, and never worked in deeply, for our aim should be the production of side or lateral fibers, and not coarse perpendicular roots. Furthermore, seedling nut trees grown on light, sandy soils or in pure leaf mold, produce a far greater number of small fibrous roots than on heavy soils, and this is a decided advantage with those which are to be transplanted.

Planting the Nuts.—When the time arrives for planting, take the nuts from their winter quarters, and after sifting out the sand, sow or drop them in drills, covering about two inches deep with fine soil. With the small native varieties my practice has been to sow in wide drills; that is, those made with the blade of a common garden hoe, and of the same width, the nuts being scattered along the bottom two to three inches apart.

The soil is then drawn in over them and pressed down with the back of the hoe, or by passing a light garden roller over the surface. If the size of the seedbed is not limited, or only a small quantity of nuts are to be sown, then the single row would be preferable, because less hand weeding will be needed to subdue the weeds, and for all the larger varieties I should certainly recommend it, because they are of a more stocky growth. The distance allowed between the drills will depend somewhat upon the implements to be employed in cultivation, as well as how long the seedlings are to remain in the seedbed before transplanting, but from two to three feet will be found convenient for the ordinary modes of cultivation.

If the seedlings make a fair average growth the first season they will be from one to three feet high in the autumn, and as soon as the leaves have fallen they may be taken up, or allowed to remain until the following spring and then lifted. But if, from any cause, they have made a feeble growth, it is better to let them remain in the seedbed another year. Where large quantities of seedlings are raised they are usually taken up with a tree-digger drawn by a span of horses or mules, but with only a few hundred or a thousand to dig, a common spade will answer every purpose; and if, when removed from the seedbed, they are found to have produced long perpendicular taproots, these should be shortened to about one-half their original length. For instance, if these taproots are taken up entire and are eighteen to twenty inches long, cut away the lower half, whether it consists of one or more long perpendicular roots, as this pruning will force the plants to produce a greater number of lateral roots, and it is upon these we depend mainly for keeping our trees alive and vigorous if transplanted when larger and older. All side branches should be pruned off close to the main stem, for we aim to favor the latter in its growth upward until it reaches the required hight for either grafting or forming the future head of the tree.

In taking up seedlings, it is not safe to leave them for any considerable time exposed to the sun and drying winds, and they should be carried either to a shed or other building while being pruned, and also covered with blankets in the field, except during moist, cloudy days. A very little drying of the small fibers on such plants is always more or less injurious.

Planting in Nursery Rows.—After the seedlings have been taken from the seedbed and pruned, they should be set out in nursery rows, four feet apart, and the plants about eighteen inches in the row. Trenches should be opened for the reception of the plants, and wide enough to allow all the roots to be spread out in a natural position; and it is well to set a little deeper than the seedlings were in the seedbed, because newly plowed ground will settle some after the planting is finished, although the soil should always be packed firmly about the stems of newly set trees, whether large or small. The more frequent and thorough the cultivation during the ensuing summer, the more rapid will be the growth of the trees.

If the transplanted seedlings have produced any considerable number of side branches,—and especially, low down,—these may be pruned off at any time during the summer, for our object is usually to secure straight, upright stems for grafting the following spring, if they are large and tall enough; if not, we may delay this operation for another year. Of course, small chestnut stocks may be grafted close to the ground, but there is nothing really gained by this, for a good strong stock will push a cion forward more in one season than a weak stock in two or three seasons. But when the stocks have reached a diameter of from three-eighths to one-half an inch three or four feet from the ground, they may be grafted, but I would prefer to have them a little over than under these sizes.

Stocks From the Forests.—It is not necessary for a man who may need a few chestnut stocks for experimental or other purposes, to wait until they can be grown from the nut, because these can always be purchased at the nurseries; but if one does not wish to incur even this small outlay, it may be avoided by obtaining a supply from the forests, provided there are any in the neighborhood where chestnut seedlings are to be found, and the owner will permit their removal. The best wild stocks are usually to be found in recent clearings, or where the larger trees have been cut off for timber, and the underbrush, composed of seedlings and sprouts, is left to grow up again into a forest. There are many thousands of acres in New Jersey, New York, and other Eastern States, from which the timber is cut every twenty or thirty years, and no further attention paid to the land or what it produces. Wherever such clearings are found containing chestnut trees, good stocks can usually be procured by selecting those varying from one to two inches in diameter at the ground, and if the soil in which they are growing is rather poor and stony they will usually have pretty good roots, if carefully taken up. They should be pruned to a single stem, and this cut off at a hight of from five to six feet or less, then planted where they are to remain permanently. Such stocks, if carefully taken up and planted, will throw out numerous sprouts from their stems during the summer, but all should be rubbed off while small and tender, except three or four at the top, and the following spring, if wanted for this purpose, they may be grafted in the same way as the young stocks growing in the nursery, thereby saving three or four years of time in securing bearing trees. Having often employed such wildings for stocks with just as good results as with those raised from the nuts in nursery rows, I am inclined to recommend them, where obtainable, knowing that there are thousands of farmers and owners of small places in the country who can do likewise, but may have never thought it practicable to transplant nut trees from the forest, although well aware of the fact that elms, maples, and similar kinds were obtained there, and in immense numbers, for planting in the streets of villages and alongside country highways.

The Season for Grafting.—The proper time for grafting the chestnut is in early spring, just as the buds begin to swell, but not until all danger of freezing weather is past, although light frosts will not seriously injure newly set cions. The grafting may be continued while the leaves are unfolding, provided the cions were cut early and stored in a cool place, where they remain in a dormant state until used. I usually cut the shoots wanted for this purpose during the late fall or winter, and then pack them away in a cool cellar between layers of damp moss (sphagnum) to be obtained in almost any swamp. Cions may be taken from the tree on the same day that they are used, but there is some risk in this, because we cannot control the weather, and a week of warm rain in spring may delay us in grafting, while it is pushing our stocks into leaf; and then, our dormant cions are available, while those on the trees are not, owing to their expanded and tender buds.

The shoots used for cions are those of the previous season's growth, or as usually termed, one-year-old wood; and in selecting these, endeavor to get such as are plump, well ripened and firm. If taken from young and very thrifty chestnut trees, there is likely to be a considerable portion of the upper end of the shoot that is rather soft, spongy and immature, and this should be discarded, as it would be a waste of time to use it. Of course, I am supposing that the grafter is so fortunate as to be able to make his own selection of the wood desired; if not, then he may be compelled to do the best he can with that obtained elsewhere.

Grafting Materials.—The really essential materials and implements required in grafting nut trees are few in number. Grafting wax must be provided, and while there are many different compositions used for this purpose, I much prefer, for ordinary work in the open air, a wax made after the old formula, and as follows: Take one pound of common rosin, one-half pound of beeswax, and one-quarter of a pound of beef tallow; melt together and stir enough to insure the thorough intermingling of the ingredients, and then set away to cool, or pour into cold water and work up into cakes or rolls and wrap in paper until wanted for use. Larger quantities may be made if required, preserving the same proportions of the materials used. If to be used immediately in grafting chestnuts and similar trees, then procure some sheets of tough Manilla paper of only moderate thickness, and cut this up into sheets about six inches wide and a foot long. While the fresh-made wax is melted, take an old and rather stiff paint brush, dip it into the hot wax and coat the papers thinly with it, and then spread them out on shelves or elsewhere to cool, and let them remain undisturbed until wanted for use. Any thin kind of cloth may be used instead of paper, but I prefer the latter because it will yield to the pressure of the enlarging stock and cion when growth begins, and it will not be necessary to examine the grafted stock so frequently during the summer to prevent girdling, as is usually the case when a tougher material is employed for wrappers. Before these waxed sheets are taken into the field for use, lay each one separately on a piece of board with the waxed side up, and with the point of a sharp knife cut them crossways into narrow strips of from one-half to three-fourths of an inch wide. But for convenience in handling, insert the point of the knife a half-inch from one edge, but cut the other clean through, so that the whole sheet of strips can be lifted together.

In early spring there is usually more or less windy weather, and if waxed sheets of paper are taken out into the field unprotected they are very likely to become tangled up and useless. To prevent this, procure a number of large but very shallow paper boxes, such as can usually be had at the stores and groceries of almost any village, and in these place a single layer of the cut waxed sheets, where they will be protected from wind and dust until removed for immediate use.

Other kinds of grafting wax can, of course, be used, and are usually procurable at the seed stores or made at home, and I have given their composition and the formulas for their manufacture in my work, "The Propagation of Plants;" but, as I have already said, this old standard kind of wax is just as good as any other, although a little more troublesome to use on account of its sticky consistency. Raffia or bass may be employed as ligatures for holding the cions in place, then covered with Leport's or other kinds of liquid grafting wax; but when these are employed it will be necessary to examine the grafted trees frequently, in order to cut the ligatures to prevent girdling.

The best implement for grafting is a common broad-blade pocket knife. One with a blade three to three and a half inches long and three-fourths of an inch wide, is a handy size. It should be of the best material for grafting chestnuts, because the wood of this tree is coarse-grained, and so filled with siliceous matter that it soon dulls the keenest blade, and the grafter will, of necessity, have to use his whetstone frequently. In grinding the knife-blade have the sides a true level, from the back to the edge, especially the underside when to be held in the right hand with the edge towards the body. The importance of having a blade of this form will soon become apparent when the grafter attempts to make a true sloping cut on either stock or cion, and it would be well for the novice to practice for an hour or two in splicing some worthless twigs before commencing upon more valuable material, for even an expert workman is very likely to make some awkward dissections and joints when out of practice. The professional propagator of plants may think such details are unimportant, but I wish to impress upon the amateur that in grafting nut trees we are dealing with kinds that will not respond satisfactorily to such free manipulations as the apple and pear; consequently, better and more careful handling is required to insure success.

When ready to begin operations in the field, take out a quantity of the shoots to be used for cions, and keep them wrapped in damp cloth or packed in a box, basket or other receptacle with wet moss, to prevent drying. If any considerable number of stocks are to be grafted, then an assistant or two will be required, for the grafter cannot be alternately handling the knife and cions and wax, and do good work, but if he only inserts the cions and his assistant applies the waxed ligatures, the operation will proceed more rapidly and satisfactorily.

Modes of Grafting.—The only two modes of grafting that I shall recommend for the chestnut are the splice or whip graft, and the cleft or wedge graft. In the splice graft, the cion and stock should be of about the same diameter, but if there is any difference let it be in favor of the stock, and this the largest. In this mode of grafting, the stock is cut off with an upward slope, exposing two or three inches of wood; and about midway on this slope a small cleft or incision is made, forming what is called a "tongue." The cion is then cut in the same way from the upper end downward, with a corresponding incision, as seen in Fig. 13. Then the two are neatly fitted together, the tongue on one entering the cleft on the other, making a close joint, as shown in Fig. 14. The bark of the cion and stock should be exactly even on one side at least; and if they are of the same size, so much the better, for then they will be even on both sides; but we cannot expect to secure such perfect joints on every stock, or any considerable number, although we aim to do so as frequently as possible. When the cion is fitted, the waxed paper is applied by placing one end of the strip at or near the base of the splice, then wind it spirally and firmly upward until the entire wound is covered. If one of the waxed strips is not enough use another, for it will do no harm if they are double on a part or all over the joint. The cion should not be much over four inches long, and a less length is preferable, but not so convenient for handling. One good prominent bud on each cion is sufficient, and this left near the upper end, but on short-jointed wood we may use cions with two or more buds without greatly increasing their length. After the cion is in place and every part of the splice is carefully sealed with the waxed paper, place a small piece or a little wax on the upper end of the cion, just enough to cover the exposed wound and prevent evaporation of the natural moisture or sap in the wood. I have found, in practice, that this sealing the end of the cion is time well spent; in fact, to leave any of the wood cells exposed to the air endangers the success of the operation.

Young shoots from a quarter of an inch in diameter up to five-eighths may be used for cions, in splice grafting; and with a little care in the selection of stocks, or by cutting them off a few inches higher or lower, we may readily manage to have them nearly of the same diameter to match our cions, whether they are large or small, and such unions will soon heal over, leaving no scar at the point where the two have been joined.

If the new growth or shoot to be employed as a cion is slender and feeble, then the base of the cion may be of two-year-old wood, leaving just a bud or two on the upper end of the one-year shoot. But it will seldom be necessary to employ such cions in grafting the chestnut, although it may occur when seeking to secure wood for propagation, from very old trees which have made only a feeble annual growth.

Cleft Grafting.—This method is employed principally upon stocks or branches of trees too large for splicing. The stock is first cut off at the point where it is desirable to insert the cion; then split with a knife, being careful to divide it, so that the edges will be kept smooth, and not rough and ragged (Fig. 15). When the knife blade is withdrawn, the cleft may be kept open with a hard wood wedge, if the stock is too large to admit of opening it with the point of the knife when ready to insert the cion. The cion may be three or four inches long, containing two or more buds; the lower end is cut wedge-shape, as shown in Fig. 16, and slightly the thickest on the side to be set against the bark of the stock. In stocks of an inch or more in diameter, two cions, one on each side, may be inserted (Fig. 17), and if both grow one should be cut away, else the tree, in later years, will be very likely to divide or break apart at this point. In stocks of an inch or less in diameter, one cion is sufficient, the top of the stock to be cut off with an upward slope, as shown in Fig. 18. After the cions are inserted, the entire exposed surface of the wood must be covered with grafting wax or waxed paper, and usually both may be employed with benefit. All the various forms of grafting in the open air, as described in my work on the "Propagation of Plants," may be employed on the chestnut, but the two here given will probably answer just as well as others for those who may have occasion to propagate this tree.

Success in Grafting.—The question has been asked many times, and will, no doubt, be frequently repeated, "What percentage of cions should one accustomed to grafting make grow?" As there are no statistics upon which to base an answer to the question, I can only give my own personal experience, and this leads me to say that seventy-five per cent may be considered an excellent, if not a high average. In some seasons this has been exceeded by at least ten per cent, while in others it has fallen as much or more below, with no apparent reason for the difference. Ninety-five per cent of the cions may push their buds, or even make a growth of several inches, then begin to die off; consequently, the time to count your successfully grafted trees is in the autumn, and not in spring or midsummer, as it is to be feared some are in the habit of doing when making a report upon what they call success in grafting nut trees.

Growth of Cions.—Cions set in strong stocks usually make a very rapid and vigorous growth, and if left unchecked, there is danger of loss by being broken or blown off by strong winds during the summer and autumn. To prevent this as much as possible, it has been my practice to pinch off the ends of the young shoots when they are about two feet long. Lateral shoots will then push out freely, and in some seasons it may be necessary to check their growth in the same way later. On feeble stocks, or those quite small, and with the less vigorous growing varieties, no summer pinching or pruning will be required. My experimental grounds are well protected upon the north and west, not only by rising ground, but by Norway spruce and American arbor vitÆ hedges twice as high as the grafted chestnut trees in the nursery rows, and yet almost every season some of the stronger-growing grafts are blown out or broken off by the wind. After the first season there is little danger of injury, probably because the union between cion and stock has become stronger.

Grafting Chestnut Sprouts.—In grafting the vigorous sprouts that always spring up from the stumps of old trees that have been recently cut down, we may reasonably expect a prodigious growth of the cion the first season, as well as in succeeding ones, and if all goes well with them we will secure large bearing trees in a very few years, but such stocks are only available where old trees are sacrificed for their timber or other purposes. Having a few such sprouts on my place, they have been utilized from time to time in testing some of the newer varieties. In one instance I allowed the cion, set on a sprout about one inch in diameter, six feet from the base, to grow unchecked throughout the season, as it was in a protected position, and in the fall the entire length of the main stem and lateral branches was sixty-five feet, and all from one bud on a cion set early in the spring. The third year this tree bore about a peck of very large nuts, to which I shall have occasion to refer again under "Injurious Insects."

Grafting Large Trees.—Grafting large chestnut trees with stems of six inches or more in diameter, and with large spreading heads, is possible, but far from being economical or practicable, especially if the trees stand out where they will get the full sweep of prevailing winds. By cutting off and grafting a few of the branches at a time for several seasons in succession, one may, in a few years, succeed in getting the entire head grafted, but there is constant danger of some of the cions being broken out if they make a vigorous growth, leaving a distorted and ill-shapen tree. Having experimented somewhat in this line with variable success, I am not inclined to recommend it, because ten trees can be raised to a bearing age on moderate-sized stocks with less labor, and the results will be more satisfactory.

Budding Chestnuts.—I have frequently tried budding chestnut stocks as described for the almond, and extensively employed with other kinds of fruit trees. But the results of my experiments have been unsatisfactory, although buds were set from very early in summer until late in the fall, also on young and old wood; but so few have taken and remained alive over winter that my personal experience in this mode of propagation will not justify its recommendation to others. Perhaps there is some secret connected with the operation that I have not yet discovered, but which is known to other propagators. Of course, budding with semi-dormant wood and buds in spring, as soon as the bark will peel from the wood, is practicable, but there is really nothing to be gained by this mode of propagation over that of grafting.

Transplanting and Pruning.—There is no tree that will bear or withstand more severe pruning than the chestnut. If trees of one or five hundred years of age are cut down, the stumps are sure to throw up an immense number of sprouts from adventitious buds, as these are readily produced at almost any point on the sapwood or alburnum under the bark; and yet, with this inherent vitality and faculty of recuperation, the chestnut tree does not naturally, like many other deciduous kinds, throw up suckers from the roots. Keeping this peculiarity in mind, the cultivator has only to use his pruning knife freely upon the trees to secure almost any form desired. But after the trees have become well established, very little pruning will be required, except to occasionally thin out or remove a rambling branch, to secure a well-balanced and shapely head to the tree.

In transplanting from the nursery rows, after grafting, and especially if the trees are of some considerable size and large enough to set where they are to remain permanently, there is sure to be a loss of roots, and those that are preserved are likely to remain for a short time inactive and incapable of absorbing nutrients from the soil to which they are transferred, or until new rootlets are produced. Under these conditions we aim to favor the roots by removing or cutting back the greater part of the branches. No matter how carefully such trees are lifted and their roots protected during the operation of transplanting, it will check the growth, and the best and most practical restorative is severe pruning of the top, and every young shoot of the previous season's growth should be cut back to within three or four inches of its base. I am presuming that the trees have been grafted only one year, but if older, and the cions were set high enough to begin the formation of the head of the tree, then the entire young growth may be cut away and some of the older wood, but of course not below the graft. All broken roots must be cut off; and the ends of the larger ones, roughly severed with the spade or other implements employed in digging, should have their wounds smoothed with a sharp knife.

Frequent transplanting and root-pruning young nursery stock tends to keep up a proper root system, and an abundance of small fibrous roots near the main stem, and trees so treated are worth much more, if to be transplanted later, than those left undisturbed; but while the latter may be twice the size of the former when of the same age, they are not worth half as much to the purchaser, or for transplanting in our own grounds.

Staking Transplanted Trees.—This is always necessary for recently planted trees, if they are of any considerable size, or from six feet high and upwards. If not supported by stakes they are sure to be swayed about, if not thrown over, by strong winds in summer. A strong stake, two or three inches in diameter, would better be set at the time of planting the tree, thereby avoiding breaking off or crushing the roots, as frequently happens when stakes are driven down among them later in the season. Set the stakes or drive into the subsoil six inches from the stem, then use strips of cloth, sacks, carpet, or some similar material, for tying, because hard cord or twine will be very likely to cut through the tender bark from the constant swaying about of the stems. Wind the strips around the stem, and then cross between it and the stake once or twice, to prevent the tree from pressing against or coming in contact with the stake. Renew the stakes and tying materials, if necessary, until the trees become firmly established, and provided with lateral roots large enough to keep them in an upright position.

Mulching.—Placing a few forkfuls of coarse stable manure, half-rotted straw, leaves, or any similar material, on the surface about the stems of recently planted trees, will prove very beneficial, in not only keeping down the weeds, but aiding greatly in retaining moisture in the soil about the roots. The application of some such material as a mulch is all the more important with the chestnut, because these trees are always to be planted in a naturally dry and well drained soil.

Distance Between Trees.—How far apart chestnut trees should be planted will depend very much upon the species and varieties, some growing to immense trees, while others are only fair-sized shrubs at maturity. But for the larger-growing varieties, forty to fifty feet between the trees is none too much space, when planted for their nuts and not for timber. If set in a single row along the public highways, farm lanes or around the outbuildings, to serve as shade or ornament, and for their nuts, then about forty feet will answer very well for the larger-growing species; and I will add that, in my opinion, all the larger kinds of nut trees will give better returns if placed in such positions, than when set in orchards or in compact masses. When set in single rows or widely scattered, they are less liable to be attacked by insects and diseases, while they will still serve the double purpose of being both ornamental and useful. I must admit, however, that in my experimental grounds the trees are planted only twenty feet apart, but with the expectation of soon cutting out every alternate specimen.

Soil and Climate.—The chestnut thrives best in light, well-drained soils, and those containing a large proportion of sand or decomposed quartz, slate, or volcanic scoria; but it is rarely found, nor does it succeed, in heavy clays, limestone soils, or on the rich western prairies, where we might think it would grow most luxuriantly. That limestone soils are inimical to the chestnut has often been disputed, but my own observations, which have been somewhat extensive in years and range of country, rather confirm the impression that this tree avoids land containing any considerable percentage of lime. It is true that chestnut groves, and sometimes extensive forests, are found on hills and ridges overlying limestone, but a careful examination of the soil among the trees will show that it is a drift deposit containing little or no lime. Such groves can be found in all the southern tier of counties of New York, also among the hills of northern and western parts of New Jersey, and thence west and south along the Blue Ridge and Alleghany mountains to the Carolinas, and westward in Tennessee and Kentucky. The chestnut is sometimes found in New Jersey and other northern Atlantic States growing in considerable abundance near streams only a few feet above sea level, but when found in such situations the subsoil is invariably sand, gravel or porous shale.

The range of climate in which the native sweet chestnut thrives is quite extensive, as it is found sparingly in Maine in latitude 44°, extending westward,—but not very abundant on this line,—through New England and New York, crossing the Niagara river, skirting the north shore of Lake Erie in Canada, and thence into southern Michigan, but does not reach Illinois. From this line southward it increases in abundance in Virginia, western North Carolina and eastern Tennessee and Kentucky. But in following this tree southward we meet another indigenous species, widely known as the chinquapin (Castanea pumila). This species is indigenous to southern New Jersey, and sparingly in parts of Pennsylvania, becoming more plentiful as we proceed southward, the two species named overlapping and in part occupying the same region; but the chinquapin extends further south, and also to the westward, near its northern limits crossing the Mississippi into southern Missouri, then extends south again, becoming quite abundant in Arkansas.

The European chestnut, in its many varieties, extends over about the same number of degrees of latitude in Europe as our species do here, although reaching a higher latitude in countries bordering on the Atlantic, as shown in the old chestnut trees of England. The Oriental chestnut has also a very wide range, but the limits are not so well known as those of the European and American species; but a study of its geographical distribution is of considerable importance, now that we are importing these nuts for cultivation. The same is also true of the European varieties, and the cultivator who neglects to take this matter into consideration will fail to secure whatever advantages may have accrued from acclimation, an agency which, undoubtedly, has been active and continuous in modifying and changing the primary characteristics of these plants during unknown ages.

To more fully impress upon the reader the importance of care in the selection of materials to be employed in any pursuit with which he is not perfectly familiar, I am prompted to relate the story of my first personal experience in chestnut culture, as it may serve as a warning to others who may attempt to raise these nuts in a cold climate.

At the time of purchasing the farm which has been my home for the past thirty years, nut trees of various kinds were on my list of things wanted, and the chestnut occupied a leading position, probably because there were already many old and large native trees on the place. My first planting consisted of a number of imported seedlings, obtained from a well-known French nursery. The trees were three or four years old, very stocky and vigorous, and they made a good growth the first season; but the following winter the young shoots were all frozen down to old wood, with the exception of one tree, and thinking that this might prove hardy, cions were taken from it and set in thrifty sprouts growing in a grove near by. The cions made rapid growth, and from one of these I soon had a large tree, which remained in good health for twenty years, but during all that time it produced but one bur, containing two half-developed nuts. Why it was unfruitful I do not pretend to know, but it was certainly not for want of company, for it had large native chestnut trees all about it, and these bearing heavy crops. The seedling trees planted in the orchard also failed to be fruitful, and were finally dug up and burned. Thus ended my first experiment in the cultivation of the European chestnut. Had my location been farther south and in a milder climate, the experiment might have ended differently, but I am relating experience, and not attempting to guess what might have been the results under more favorable conditions. In the meantime, however, I had seen a few trees of the Japan chestnut bearing on Long Island, and had received specimens of the Numbo and Paragon, two now well-known and superior varieties of the European species, although raised in this country. These varieties were secured, and succeeded so well that I have continued to add others from time to time, or as soon as trees or cions were obtainable.

The success which appears to have attended the propagation and dissemination of these two varieties of European parentage has awakened considerable interest in chestnut culture, besides attracting the attention of those interested in such matters to the fact that there are many old trees of the same or similar origin scattered about the country, awaiting the coming nut culturist to propagate them and make known their merits.

It may be well, before leaving this subject, to remind the novice in chestnut culture that seedlings of these hardy and productive descendants of the European species will not come true from the nut or seed, and while it will be admitted that the chances are somewhat better for procuring a hardy variety from such nuts than from those imported, still, there is no certainty of any considerable number being equal in hardiness or other respects to the parent tree. There is an inherent tendency, in tree seedlings of all kinds, to revert to the wild form or type, and the chestnut is no exception to this rule.

Species of Chestnut.—What is called a "species," among plants, is a particular form or type supposed to have descended from one original stock, whether this was composed of one or more individuals. But variations doubtless occurred at the first inception or multiplication of the original, but so long as the offsprings do not differ so widely as to be untraceable to the proemial types, they are held to be varieties of one species.

Whether all the chestnuts found in the various countries of the world are descendants of one original tree or group of trees is now beyond our ability to determine; consequently, what are now termed species rests very much upon the opinions of botanists, as may readily be demonstrated by consulting the works of hundreds of authors who have essayed to describe and classify the plants of any locality or country, and this, too, without reaching an absolute finality acceptable to their contemporaries, or at all likely to share a better fate with posterity.

For many years after botany began to be recognized as a science, the common American sweet chestnut was considered a distinct species, but in recent years it has been relegated to the position of a widely distributed variety of the European chestnut, and it is so described and classified in most of the botanical works of the present time, and under such names as Castanea vesca, variety Americana; Castanea sativa, variety Americana; Castanea vulgaris, variety Americana, etc.

The Asiatic species or varieties—under whichever cognomen we may find them described in botanical works—have fared little better than our American kinds, for some botanists have described the Japan chestnut as a distinct species, while others only as a widely divergent variety of the common European chestnut.

I regret that there should be any need of giving so much space to this matter of species and varieties, yet presuming that far the larger number of my readers will not be professional botanists, nor persons with a botanical library at hand to consult for unfamiliar terms, I have thought this explanation in regard to classification might assist them in making clear the apparent confusion of names which, in the main, are only synonyms. Furthermore, I purpose retaining some of the older specific names of the distinct groups of varieties, whether it be strictly in accord with the ideas of eminent authorities or otherwise, because it will be more convenient to do so, and certain phases will thus be made clearer to the practical cultivators of nut trees, for whom this work is written. My wish is to assist those who do not know, but want to learn how to obtain, plant and make nut trees grow and bear remunerative crops.

Castanea Americana (American sweet chestnut).—Leaves oblong-lanceolate, serrate, with rather coarse teeth, each terminated with a feeble prickle or spine; smooth on both sides (Fig. 19). Burs thickly covered with sharp, branching spines a half inch long or less, from a fleshy green envelope, becoming hard and somewhat woody; opening by four valves or divisions when mature. Usually three nuts in each bur, the center one flattened by compression, the two outer ones plano-convex. Shell tough and leathery, dark brown, smooth, or more or less inverted, with a silvery pubescence from the point downward; variable in size from five-eighths to an inch in diameter. Kernel sweet and fine-grained. A very large and common tree in the Middle and Northern States, living to a great age.

Castanea Nana (bush chinquapin).—Leaves oval-lanceolate, serrate, with feeble prickles on teeth and often wanting; pale green above and white tomentose underneath. Burs in racemes, small; husk thin, opening by two divisions or lobes, instead of four, as in the last species; spines short, somewhat scattering, sessile or very short-stalked; nuts small, pointed, brown, smooth, thin-shelled, solitary or only one in a bur. Kernel fine-grained, sweet and delicious. Common from North Carolina southward to Florida, in dry soils and barrens. A medium-sized shrub or low-spreading bush, rarely reaching a hight of ten feet, the slender twigs usually tomentose. A spike of burs and leaves of this species are seen in Fig. 20.

Castanea Pumila (chinquapin chestnut).—Leaves oblong-lanceolate, short or acutely pointed, coarsely serrate, with incurved pointed teeth, green above, tomentose underneath. Burs in racemes (Fig. 21), two-valved. Sometimes the burs are single, as shown in Fig. 22. Spines branching from a short stalk; nuts solitary, ovoid, pointed, with dark-brown polished shell. Kernel fine-grained, sweet and excellent. A medium-sized tree twenty to forty feet high; in rich soils from New Jersey, Southern Pennsylvania and southward, to Georgia, and sparingly westward to Arkansas.

Castanea Sativa Or Vesca (European chestnut).—Leaves oblong-lanceolate, pointed, coarsely serrate, with rather long incurved spines on the teeth; smooth on both sides, but glossy and dark green above; thicker and of more substance than in any other species. Burs very large, with thick husk, and long, stout, branching spines, from a woody stem at the base; shell of nut thick, tough and leathery, of a dark mahogany brown; kernel enclosed in a rather tough but thin skin that is usually intensely bitter, a characteristic that readily distinguishes this from any of our species. Trees of large size, rather stocky; young shoots coarse, with smooth bark; buds prominent, glossy, and of a light yellowish-brown color.

Castanea Japonica (Japan chestnut).—Leaves lanceolate-oblong (Fig. 23), finely serrate, indentations shallow, and the teeth slender pointed; pale green above and silvery or rusty white underneath. Burs with a very thin husk; spines short, widely branching from a short stem. Nuts large to very large, usually three in a bur; shell thin, and of a light brown color; the inner skin thin, fibrous, but not as bitter as in the European varieties, and the kernel somewhat finer grained and sweeter. Trees of moderate growth and are said to rarely exceed fifty feet high in Japan. The growth is slender in comparison with the European or American chestnut, and the habit is decidedly bushy, the new growth of the season usually producing a number of lateral twigs late in summer. The leaves here seem to be more persistent, probably because the season is not long enough to insure thorough ripening.

The reader will please bear in mind that this description of the Japan chestnut is drawn from the introduced varieties or those raised from the imported nuts, and not from the trees growing in their native habitats. All the varieties that I have seen appear to belong to one type or species, and they come from the warmer parts of that country; but Prof. Sargent, in his "Forest Flora of Japan," says that while the largest nuts appear in the markets of Kobe and Osaka, from whence they come to this country, there are varieties offered for sale in the markets of Aomori, which is much further north, and these, he thinks, would produce a more hardy race of varieties than those we have already received from that country. As a race, all the Japan chestnuts are very precocious, the trees coming into bearing early whether raised from the nut or propagated by grafting.

Native Varieties. (Group One).—While it is well known that our American sweet chestnut varies widely in the size, flavor, form, color and general appearance of the nuts, no special effort has been made to select and perpetuate the most distinct and valuable varieties. This is to be regretted, inasmuch as the opportunities for making such selections, and preserving and propagating those most worthy of it, are rapidly passing away with the destruction of our chestnut forests; but there is still time to do something in this direction, and perhaps save a few varieties as valuable as those already destroyed. It is to be hoped that every man who knows of a large variety, will either propagate it himself, or point it out to some one who is sufficiently interested to do so. If proper attention was given to the raising of seedlings, we might soon secure many improved native varieties, and I would urge this mode of propagation upon all whose circumstances and surroundings will admit of it, and especially upon the young men who possess the talent and inclination to make such experiments; for there is a wide and fertile field open to them, and they can scarcely fail to reap a rich reward for their labors, if applied with earnestness and a moderate amount of intelligence.

Burless chestnut.—This is a peculiar variety or freak, in which the burs are merely shallow cups upon which the nuts rest, and at no stage of their growth are they enclosed in a husk or bur. The nuts are small and usually perfect, but being unprotected they are preyed upon by birds and squirrels as soon as the kernels are well formed, few escaping to reach maturity. This chestnut is of no economic value, but is worth preserving as an illustration of extremes in variation. The original tree was found in the forest near Freehold, Green Co., N. Y., by Mr. Harry Bagley, to whom I am indebted for cions sent me in the spring of 1885. Another and very similar variety was found about the same time on Staten Island, N. Y., and this also has been propagated, to a limited extent, as a curiosity.

Hathaway.—A very large and handsome native variety, and one of the very best. A strong and vigorous grower, and productive. Raised by Mr. B. Hathaway, the veteran and widely known pomologist of Little Prairie Ronde, Mich. Some thirty years ago Mr. Hathaway purchased a half bushel of native chestnuts of a dealer in Ohio, and from these raised a large number of trees for sale; but a few were reserved for planting out on his own grounds, and when these came into bearing the one named here was selected for propagation, because of its large size and productiveness.

Phillips.—A large and handsome variety of excellent flavor, with a very smooth, dark-brown shell. Grafted trees exceedingly vigorous, upright growth, as well as precocious and productive. The original tree is growing in the grounds of the late Whitman Phillips, at Ridgewood, N. J. Several years ago my attention was called to a number of large varieties of the chestnut growing in and near the village, and from these I obtained cions for propagation; but I name only one at this time, reserving the others until more fully tested.

This is rather an insignificant number of varieties to be named among the many hundreds that are to be found in almost every town or neighborhood where the chestnut is a native, and yet I have been able to find only one named in nurserymen's catalogues as being propagated by grafting. It is true that nearly all dealers in trees offer seedling American chestnuts, which may mean good, bad or indifferent varieties when the trees come into bearing. Among all of the many thousands that have been raised and planted in the East and West, beyond the natural range of the chestnut, as, for instance, in Missouri, Kansas and Iowa, there must be some distinct and valuable varieties worthy of names and propagation. There are not only distinct varieties to be found in every forest, but in some instances the entire product of an extended area of country are distinct in their color, size, and general appearance of the nuts produced; as, for instance, in the woolly chestnuts of the Piedmont district of Virginia, these being so nearly covered with a white down that they remind one of popcorn. Hundreds of bushels of these woolly chestnuts come to our markets, and among them I have often found very large specimens, but so far as known, no effort has been made to perpetuate them.

So far as can now be determined, the wild or original European chestnut was much inferior in its flavor, and little, if any, larger than our American sweet chestnut; but by continued selections of the largest for planting, and propagation by grafting, it has attained to its present size and excellence; but this system of improving our native varieties has scarcely, as yet, been attempted, a fact which does not, in the least, redound to our credit.

Bush chinquapin (C. nana. Muhlenberg).—Of this I do not know of any named varieties in cultivation. Plants are occasionally seen in cultivated grounds, and I have one in my garden growing in a sheltered position, where it has fruited for several years. It is a pretty, round-headed, silvery-leaved bush, about six feet high; ornamental, if not specially valuable for other purposes, although the little sweet nuts are always acceptable. As a rule, the seedlings of this species are not hardy in the Northern States, but an occasional one will survive if planted in a light, porous soil and a protected situation.

Common chinquapin (C. pumila. Miller).—This is a small tree, sometimes thirty to forty feet high; found sparingly as far north as central New Jersey, and on Long Island. It is more common in cultivation than the bush chinquapin, probably because more hardy and better known, but I do not know of any improved varieties that have been disseminated under distinct names except the one hereinafter described.

Among many seedlings raised, of this species, I have selected one which good judges of such things have thought worthy of propagation, and as I do not raise plants for sale, no one will be likely to accuse me of having any selfish motives, further than a pardonable pride in producing something worthy of perpetuation. Furthermore, as an earnest of my confidence in its merits, I have distributed it under my own name.

Fuller's chinquapin.—Leaves large, broadly oval, pointed, coarsely serrate, pale green above, clear silvery white below. Bark on main stem; branches and twigs smooth, light gray, with numerous white dots. The young twigs thick and stocky, cylindrical, with moderately prominent, grayish buds. Burs in long racemes (Fig. 24), very large for this species; spines long, strong, branching and sharp. Nuts only one in each bur, rather short, broad, top-shaped, with blunt point; shell very smooth, glossy, almost black; kernel fine-grained and sweet. Ripens early, or with the earliest of the native sweet chestnuts. The original tree is only six years old, twice transplanted, and is now ten feet high, with a head fully as broad, and as shown in Fig. 25. Although growing in a rather exposed position, it has never been injured by low temperature in winter or a high one in summer. It has thus far been the most rapid-growing chestnut tree in my grounds, although given no special care. Whether it will eventually become a large tree, or soon cease to extend, is, of course, a question to be answered at some future time, but from present indications this tree will be well worthy of cultivation as an ornamental shade tree, even if we leave out of the account its rapid growth, productiveness, and delicious little nuts, which will be very acceptable for home use, if not possessing any great commercial value.

European Varieties.—In the use of this term I wish it understood that the varieties named and described in this group are all of American origin; that is, raised in this country from seed. At the same time they are descendants of the European species. They are, in other words, "Survivals of the fittests," the few that have survived the many being raised from imported nuts (perhaps one out of a thousand) that tests and time have shown were adapted to our climate. There may be many other varieties scattered about the country which are worthy of a name and of propagation, but I can speak only of those I have been able to procure, or that have been brought to my notice.

In describing the following varieties, and in seeking to get at the facts relating to their origin, name and history, the reader will please bear in mind that there has been no previous attempt to arrange or classify these semi-American varieties. Furthermore, there is much confusion in regard to the true names of a number of them, and the most I can say is that I have endeavored, under the circumstances, to get as near the truth as possible. Could I defer writing this chapter ten years, some moot points might be cleared up, but as this is out of the question I must follow the light already in my possession.

To Mr. John R. Parry, of Parry, N. J., I am greatly indebted, not only for specimens of new and rare varieties, but also notes relating to the history of several of the older ones.

Comfort.—Burs very large, broad, somewhat flattened; spines very strong and long, branching; nuts very broad, with short point, and shell covered from base to point with scattering silky hairs, thicker at upper end. In quality, about the same as in the ordinary varieties of the species, but to some persons' taste it is better, having less astringency in the skin surrounding the kernel. Origin uncertain, but said to have been grown for many years at Germantown, a suburb of Philadelphia, Pa., where the Paragon chestnut was discovered. The Comfort certainly closely resembles the Paragon, but I have not had an opportunity of fruiting trees under the two names side by side, as would be necessary to determine their identity or difference, if they are really distinct.

Cooper.—A very large variety; has been in cultivation for several years in Camden Co., N. J., but up to the present time the trees have not been propagated for sale, although I am informed by Mr. John R. Parry that there are a large number under cultivation. The tree is described as of a broad spreading habit, with enormously large leaves, and immensely productive. Nuts very large, smooth and glossy, with little fuzz near the top. In quality they may be considered excellent for a variety of this class. The burs are very large, and this is its greatest or only fault; for when nearly mature they absorb and retain such a quantity of water during heavy rains, in addition to the original weight and the enclosed nuts, that the trees are liable to be broken down by strong winds.

Corson.—Burs of immense size; spines an inch or more in length, from a stout, woody, irregularly branching stem, resting on the moderately thin husk. Nuts extra large, usually three in a bur; shell dark brown, somewhat ridged; the upper end or point of the shell densely covered with a white, almost woolly, pubescence, or fuzz as it is usually termed. This is a remarkably large and fine variety and of good quality. Originated with Mr. Walter H. Corson, Plymouth Meeting, Montgomery Co., Pa.

Dager.—A large variety originated near Wyoming, Delaware, from seed of the Ridgely. My specimen trees are good vigorous growers, and hardy, but have not, as yet, produced fruit. It is said that the nuts are of fair quality, but not as good as the best of its class.

Moncur.—Another seedling of the Ridgely, raised on the farm of Mr. Frank Moncur, near Dover, Del. The original tree is about thirty years old. Described as smaller than its parent, but of better quality.

Numbo.—Burs medium, and distinctly long pointed before opening, as shown in Fig. 26, the four divisions of the burs extending an inch or more beyond the nut as they open. This is an exceptional form of the bur, and will enable almost any person to recognize the variety with bearing trees. Spines only medium in length (Fig. 27), and not as strong as in most other varieties of this species. Nuts very large (Fig. 28), smooth, decidedly pointed, light brown when first mature, and of good flavor. Tree hardy and a vigorous, free grower, and is very productive even when young. The original tree is now some forty years old, and is one of a large number raised from imported nuts, by the late Mahlon Moon, of Morrisville, Pa.

Miller's Dupont.—Burs large, spines long and strong but not as stout as in some of the closely related varieties. Nut medium, and kernel of fair quality. A promising variety. Origin unknown. Received from Jos. Evans, Delaware Co., Pa.

Paragon.—Burs of immense size, often five inches and more in lateral diameter; distinctly flattened on the top, or cushion shape (Fig. 29); spines an inch in length, widely and irregularly branching from a stout stem springing from a thick, fleshy husk, as shown in Fig. 30, the whole making an involucre or bur out of proportion to the nuts within. Nuts of large size, slightly depressed at the top (Fig. 31), and they are usually broader than long; shell very dark brown, slightly ridged, and covered with a fine but not very conspicuous pubescence. Kernel sweet, fine-grained, and of superior flavor for one of this species. Tree hardy, exceedingly precocious and productive when grafted on strong, healthy stock. A four-year-old tree on my grounds is shown in Fig. 32. It was loaded with nuts in the fall of 1894. This is one of the best of its class. Origin somewhat in doubt, but it is claimed that the late W. L. Shaffer, of Philadelphia, raised it from a foreign nut planted in his garden, and who, some eighteen years or more ago, gave cions to W. H. Engle, of Marietta, Pa. Mr. Engle has since propagated and disseminated this variety quite extensively under its present name, but should further investigation prove it to be distinct and that it was raised by Mr. Shaffer, then it should certainly bear his name, and Paragon become a synonym. No more appropriate monument could possibly be erected in honor of a distinguished horticulturist like the late Mr. Shaffer, than a chestnut tree, nor could his memory be perpetuated under more pleasant and agreeable surroundings than to have his name linked inseparably with such an excellent and valuable variety.

Ridgely.—Burs large, with dense spines, but not as long as those of the Paragon. Nuts large, pointed; shell dark brown, with very little pubescence, and this mainly at the point (Fig. 33). In quality this variety ranks very near, if not the equal of, the best of its class, and it has been highly commended, by those who have been acquainted with it, for many years.

The origin of the Ridgely, as recorded, leaves the question of name a debatable one. Some sixty years ago a Mr. Dupont, of Wilmington, Del., gave or sent to Mr. D. M. Ridgely, of Dover, Del., a sprouted chestnut, and this was planted and became the original tree of the variety under consideration. It has been called Dupont, because he raised the nut and kept it over winter and until it sprouted; then it passed into the care of Mr. Ridgely, who thenceforward gave it his attention. The tree is now of immense size, and some seasons has produced more than five bushels of nuts, selling at eleven dollars per bushel. It is quite probable that the Dupont family were the first to raise European chestnut trees to a bearing size in this country, for some of its members were settled in Delaware before the war of the Revolution. Pierre Samuel Dupont de Nemours, during the French ministry of Vergennes, was employed in forming the treaty of 1783, in which the independence of the United States was formally recognized by England. In 1795 (Am. encyclopedia) he came to this country and joined his sons, who had become successful manufacturers of gunpowder at or near Wilmington, Del., where their descendants, or at least some of them, are still engaged in the same business. If any of the old and original chestnut trees have escaped the numerous "powder mill explosions" which have frequently occurred in that neighborhood, they are probably much older than the Ridgely. I am also inclined to believe that a very large majority of all the hardy chestnut trees of the European species scattered about the country are the direct descendants of the old Dupont stock.

Scott.—Burs large, with long branching spines. Nuts from the original tree, as received the past season, are only of medium size, but said to be much larger on younger trees. Shell dark brown, smooth, with a little fuzz around the point. As my specimen tree has not, as yet, fruited, I am unable to say anything of its productiveness from personal experience, but in a note from Mr. William Parry, under date of Oct. 15, 1894, he says: "I send specimens of the Scott chestnuts, grown by Judge Scott, of Burlington, N. J. The crop is about gone and it was with difficulty I could get these, which are about the average size; earlier in the season many are larger. Judge Scott has grown those nuts for market several years. The original tree was bought by his father many years ago from the nursery of Thomas Hancock. He bought three trees for Spanish chestnuts, planted them in a row about thirty feet apart, and the one from which these nuts were obtained happened to be in the middle. It is now a large tree, the trunk about five feet in diameter. It is a regular and heavy bearer. Judge Scott has propagated and planted an orchard from this variety, and claims among its important features, large size and early bearing,—two-year grafts generally produce nuts; immense productiveness and good quality; beautiful, glossy, mahogany color; freedom from fuzz, and an almost entire exemption from the attacks of the chestnut weevil. While the crop of two trees standing on either side of the Scott is badly damaged by worms, it is the exception to find a wormy nut among the Scott.

"The crop sells readily at ten to twelve dollars per bushel. This year (1894) some sold as low as eight dollars, the lowest ever known for this variety."

Styer.—Burs large, round; spines long, branching, but not as coarse as those of Comfort. Nuts medium to large, decidedly pointed, and the point fuzzy. Shell dark brown, with a few longitudinal stripes, but not ridged. A handsome nut of good quality. This variety has been distributed under the name of Hannum. The original tree, which is a mammoth in size, is still standing on the farm of a Mr. Hannum, near Concordville, Delaware Co., Penn. But Mr. T. Walter Styer, of the same place, is propagating and introducing it as the Styer.

Some of the varieties in this group may not prove to be distinct, and later they will be relegated to their proper place as synonyms, but I have thought it best to record them by the names under which they have been received. In writing these descriptions I have had the nuts and leaves before me, but there may be characters overlooked which will become more conspicuous as the grafted trees become older and more mature. The Dager chestnut, from Delaware, is a promising variety, disseminated through the Department of Agriculture, but as I have not seen the nuts at this writing, a description is necessarily omitted.

Among the French varieties of this species which are said to succeed admirably in California, a large proportion would probably do equally well in Delaware and further south. Among those worthy of trial I may name the Avant Chataigne, Comale, Exalade, Green of Lemousin, Grosse PrÉcoce, Jaune Rousse, Lyons, Merle, Nouzillard, Quercy, etc. I have tried some of these, but with such indifferent results that they were abandoned. Cultivators of nut trees located in a milder climate, should take advantage of whatever improvements there have been made in Europe, by importing grafted trees or cions. There are a few ornamental varieties of the European chestnut, but none worthy of any special attention.

Japan Chestnuts.—The first authentic account I have been able to find of the introduction of the Japan chestnut into this country, is of a number of trees received by S. B. Parsons & Co., Flushing, N. Y., 1876, from the late Thos. Hogg, who, as is well known to all horticulturists, spent several years in Japan collecting many rare kinds of trees and shrubs, which were shipped direct to Parsons & Co. The chestnut trees received in 1876 fruited two years later, or in 1878, and soon attracted attention, on account of the large size and excellent quality of the nuts and the precocious habits of the trees.

The success of this typical variety of the Japanese species, as I have assumed to designate it, proved that there were oriental chestnuts—heretofore untested in this country—that were certainly worthy of an attempt to obtain. This variety, introduced by the Messrs. Parsons & Co., does not appear to have been disseminated under any distinct varietal name, but merely bears the rather meaningless one of Japan chestnut, and for the purpose of giving it a position where it may be recognized—by name at least—from other varieties more recently introduced, I shall take the liberty of calling it "Parsons' Japan."

Soon after it became known that the oriental chestnuts would succeed in this country, the fruit growers and nurserymen of California began to import and plant these nuts, shipping an occasional lot to their customers in the Eastern States, and from these hundreds of seedlings have been raised and distributed, under the general name of Japan chestnut. Among the nuts imported there are some of extraordinary size, even larger than anything of the kind obtained from Europe, as shown in Fig. 34, natural size, and from a specimen received direct from Japan. Some of the nurserymen who have secured these very large nuts for planting, offer the seedlings raised therefrom under such names as Mammoth and Giant Japan, but as there is no certainty, and scarcely a probability, that such seedlings will produce nuts as large as those planted, the names are rather misleading, although proper enough if given to grafted varieties of large size. When an extra-fine variety is produced from the nut, it should, of course, be preserved and propagated in the usual way.

The late Wm. Parry, of Parry, N. J., was one of the first nurserymen to attempt to produce new varieties of the Japan chestnut in this country, and his sons have continued his experiments in this direction. Others may have been equally successful, but I have been unable to obtain any satisfactory reports from those to whom I have applied for information; consequently, I can only say that the following, with few exceptions, originated at the Wm. Parry nurseries.

Advance (Parry).—Burs medium, slightly flattened on top; spines medium, short, almost sessile, as shown in Fig. 35, and this is a characteristic of all the Japan chestnuts; branching and widely separated on a very thin husk. Nuts very large; shell a light yellowish brown, with a few slight darker streaks from base to apex. Quality excellent for one of this species. Ripens early, and long before touched by frost.

Alpha (Parry).—Very similar to the last, but ripens earlier, which would be an advantage in some localities. Tree vigorous and productive.

Beta (Parry).—Bur medium; spines rather long and thin for one of this group, set on a thin husk. Nut large; shell light brown, smooth, with a slight trace of pubescence near the tip. The leaves are shallow and coarsely serrate, and on some the teeth or serratures are entirely wanting. Ripens a little later than the Alpha, or about the first of October in northern New Jersey.

Early Reliance (Parry).—Burs medium, with short, almost deflexed spines, on an exceedingly thin husk. Nuts large, more pointed than in the last, and of a lighter color the past season, but this may not be constant, and may be due to the long and severe drouth of the summer of 1894. Usually three nuts in a bur, and sometimes four or five, but I do not consider this increase in number a merit in any variety, for where there are more than three they are likely to be of small size and very much deformed. The original tree of the Reliance is enormously productive, and a regular bearer.

Felton.—A seedling of the common Japanese chestnut, raised by J. W. Killen, of Felton, Delaware.

Giant Japan (Parry).—Burs large to extra large for a variety of this species, with medium low branching spines on a very thin, parchment-like husk. Nuts extra large, usually only two in a bur, often only one, and about two inches broad, much depressed at the top, with a short point set in an irregular depression or basin. Shell dark mahogany color, more or less ribbed; kernel coarse grained, as is usual in the extra large varieties of nearly all species of the chestnut. This is probably the largest variety of the Japanese chestnut raised in this country, of which grafted trees are obtainable at this time. There may be others equally as large, but if so they are unknown to the writer.

Killen.—Of the Japan species, and described as very large, the nuts over two inches in diameter and of fair quality. Raised by J. W. Killen, of Felton, Del.

Parsons' Japan.—Burs medium, with rather thick-set and long spines. Nuts large, one inch and a half broad, curving regularly to a point; shell smooth, almost glossy, brown, with faint stripes of a darker shade extending from base to apex. In quality the kernel is far better than most of the European varieties, being finer grained and sweeter. When grafted on strong stocks the trees come into bearing early, or in two or three years. This is the best known, and probably the most widely distributed variety, of the Japanese species in this country, having been introduced, as I have stated elsewhere, in 1876.

Parry's Superb (Parry).—Burs broad, cushion-shaped, or much flattened on top, with extra long, widely branching spines from single or multiple stems, very much as in the European varieties. But the thin husk, the nuts, and the growth of tree, wood and leaves, stamp it as a pure Japanese variety. Nuts large, broader than long, with a decided sharp woody point; almost entirely destitute of even a sign of pubescence. A very promising and distinct variety.

Success (Parry).—Burs very large, broad, with only a few short, scattering, branching spines on the top, thicker toward the base; on a thin, parchment-like husk, and this is so thin that it sometimes cracks open and exposes the nuts within before they are fully ripe. Nuts extra large, nearly equal to the Giant, but of a more regular and symmetrical form, being nearly as long as broad, tapering to a point. Shell smooth, dark brown, with a slight pubescence about the point. Usually three nuts in a bur; an ideal variety in every respect.

There is a variety of the Japan chestnut recently much lauded under the name of Mammoth or Burbank, which is said to be of immense size, and as sweet as the common American chestnut.

Injurious Insects.—The chestnut tree is rarely attacked by insects. It is true that grubs may occasionally be found boring into the wood or cutting sinuous burrows under the bark, but this is mainly in trees weakened by exposure, in removing protecting companions, as when removing forests, or by plowing up and destroying the roots, in cultivating the land about them; but the attacks of insects upon such specimens is nature's way of getting rid of the feeble and least valuable, making room for the healthy and strong. But my thirty years' residence in a chestnut grove leads me to think that this nut tree is exceedingly free from wood borers of any kind.

Entomologists, however, have noted several instances of insect depredations upon individual trees, by a few species of the long-horn beetles, three or four in all, but these occur so rarely that they are scarcely worthy of notice as pests of the chestnut. There are also several species of caterpillars occasionally found feeding on the leaves of this tree, also some sucking bugs or tree hoppers, and two or three kinds of plant lice, but none of these have, as yet, become at all formidable enemies, or likely to become so later. But the chestnut has one enemy which is so abundant and destructive to the nuts as to call for an extended notice. I refer to the common native chestnut weevil (Balaninus carytripes, Boheman). The little fat, white, round, legless grubs, nearly or quite a half-inch long, must be familiar to every person who has handled or eaten chestnuts raised in this country, whether of the exotic or native varieties. The parents of this grub are oval-shaped beetles about one-half inch long or less; wing covers, body and legs densely covered with a short yellow down, and from the front or thorax there extends a long, slightly curved, slender snout (Fig. 36), sometimes nearly an inch in length in the females, but usually less in the males. The mouth parts are at the extreme end of this snout or proboscis, and the female, with her mandibles, it is claimed, reaches down among the chestnut spines and gnaws a hole in the husk, into which she drops an egg; and when this hatches, the minute grub cuts its way through the green husk and into the nut, the hole made in its progress closing up behind, leaving no mark or scar. Although I have taken hundreds of these weevils on chestnut trees, I never have been so fortunate as to take one in the act of ovipositing, but have come so near it as to find the ovipositor still extended as the insect crawled out from among the spines.

The chestnut weevil usually appears in great numbers soon after the trees bloom in spring, but they continue to come out all through the summer; I have occasionally found them late in September, which probably accounts for finding small and half-grown grubs in the nuts as they ripen and fall from the trees. These late grubs often remain in the nuts all winter, but the greater part escape earlier, or very soon after the crop is ripe. The grubs crawl out of the nuts and work their way into the ground to a depth of from a few inches to two feet, much depending upon the nature of the soil. Having very powerful jaws, they readily cut through a layer of leaves or soft wood, and I have known them to cut holes in sheets of dry cork. These grubs remain in the ground until the following season, then come forth in their winged or weevil stage, except the belated, broods, or those that have not reached full size in the autumn; these remain in the ground the entire summer, coming out late in the fall, or pass over until the second year, as I have proved by burying the grubs in a barrel sunk in the ground, covering the top with fine wire netting, to prevent the escape of the weevils as they emerged from time to time during the season.

As a rule, we find only one grub in a nut, of the American sweet chestnut, but in the larger varieties of the European and Japanese, two or more is not unusual, which rather favors the idea that the female weevil does possess something akin to reason, which guides her in locating stores of food available for her progeny. I have never observed that the weevils had any choice among varieties, all being subject to their attacks alike, provided all were growing in equally favorable positions. But if the trees are of different sizes, some tall and others short, some exposed to the winds and others protected, then the ravages of this pest will, no doubt, be as variable as the surrounding conditions. As the weevils emerge from the ground in spring or early summer, they will naturally seek the nuts most convenient and on the small trees, then those on the lower branches of the larger ones, while those on the upper part of the tree, where they are fully exposed to the winds, may wholly escape the attacks of these pests. This leads me to think that whoever attempts to cut off native chestnut forests, with the expectation of renewal with the larger varieties, by grafting the sprouts, will find the chestnut weevil a rather formidable enemy. I have found it so on a limited number of trees in my own grounds, that are grown from grafted sprouts near large native specimens, the weevils destroying nearly every nut; but out in the field, away from the woods, and where the young trees are scattered and exposed to the full sweep of the winds, the nuts are sound and free from insect enemies. The only remedy is to collect and destroy the weevils, which is not a serious matter where only the larger varieties are cultivated.

Diseases of the Chestnut.—I have never noticed any special disease among chestnuts, neither do I find any mentioned in European works on forestry. The nearest approach to any such malady being recorded as having appeared in this country, is found in a paragraph in Hough's "Report on Forestry," 1877, p. 470, where the author copies from Prof. W. C. Kerr, State Geologist, North Carolina, as follows: "The chestnut was formerly abundant in the Piedmont region, down to the country between the Catawba and Yadkin rivers, but within the last thirty years they have mostly perished. They are now found east of the Blue Ridge only, on higher ridges and spurs of the mountains. They have suffered injury here, and are dying out both here and beyond the Blue Ridge. They are much less fruitful than they were a generation ago, and the crop is much more uncertain."

While there is nothing said about any chestnut disease in the paragraph quoted, we only infer that the author intended to convey the idea that the trees were suffering from some endemic malady, although it may have been due to long drouths, insect depredators, or other causes. A few years later Mr. Hough, in his "Elements of Forestry," refers to the subject again, and admits that "the cause of the malady is unknown." But as chestnuts continue to come to our markets in vast quantities from the Piedmont regions, there must be a goodly number of healthy trees remaining.

Uses.—The economic value of the chestnut, as food for mankind and the lower animals, has been, and is still, so well known, that no extended dissertation or compilation of historic instances of its usefulness are required here. For almost two thousand years it has been an important article of food throughout southern Europe, and in some of the mountainous districts it is almost the "staff of life" among the poorer people, who not only use these nuts in their raw state, but roasted, boiled, stewed, and even dried and ground into flour, from which a coarse but nutritious kind of cake or bread is made. These nuts are also used in the same way by the poorer classes of China and Japan, and probably in other oriental countries. In France, Italy, Spain and Portugal, the chestnut crop is of immense importance, not only for domestic use, but commercially, because all surplus is wanted by other nations, who are ever ready to take a share, and pay a good round price for the same.

In this country chestnuts are mainly used as a luxury or a kind of pocket lunch for the children, as they are rarely brought to the table, and it is very doubtful if the American housewife, or our cooks,—unless foreign born and bred,—know anything about preparing these delicious nuts for comestible purposes. Cereals, meats, fruits and vegetables have always been so abundant and cheap in this country, that the poorest of the poor could indulge in them without stint or limit; but all this will change sooner or later, and when our population has doubled or trebled, the edible nuts must become of much more importance than now, and a roast turkey stuffed with chestnuts may figure as the ideal of gastronomic art.

As our native chestnuts are now annually consumed by the thousands of bushels, and the imported varieties by millions of pounds, and all as a mere luxury,—not a necessity nor an article which we could not dispense with without any serious inconvenience,—we may well consider what the future demand must be, and make haste to meet it with an abundant supply.
