MADRONA
(Arbutus Menziesii)
Madrona is an interesting tree which ranges from British Columbia southward to central California, attaining its greatest development in the redwood forests of northern California, where trees are sometimes one hundred feet high and six or seven feet in diameter. It is not only an interesting tree itself, but it has many interesting relatives, some of which are trees, others shrubs, and still others only small plants or vines. It may be called a second cousin to the common huckleberry, the mountain laurel, trailing arbutus, the azaleas, the tiny wintergreen, and the great rhododendron. It has some poor relations, but many that are highly respectable. It belongs to the heath family, of which there are seventy genera, and more than a thousand species; but less than half of them are in America, the others being scattered widely over the world.
The madrona, when at its best, is one of the largest members of the family; but it is not always at its best. It sometimes degenerates into a sprawling shrub, where it grows on poor ground and on cold, dry mountain tops. It is manifestly not fair to study any tree at its worst, and it is particularly not fair to the madrona, which varies so greatly in its appearance. At one place it may be scarcely large enough to shade the lair of a jackrabbit, and at another it spreads its branches wide enough to shade an army—a small army, however, say, about two thousand men. A tree of that size may be found within a few hours’ ride of San Francisco. Its branches cover an area of from eight thousand to ten thousand square feet.
When madrona grows in the open it throws out wide limbs like a southern live oak, though not so large or long. Its crown is rounded and graceful; but when it grows in forests, where other trees crowd it, the trunk rises straight up to lift the crown into the sunlight and fresh air. The madrona is seen in all its glory in northwestern California, where it catches some of the warmth and the moist air from the Pacific. It follows the ranges of the Siskiyou mountains eastward near the boundary of California and Oregon. It is usually mixed with other forest trees, but sometimes large stands nearly pure are encountered, and there the long trunks, rather gray near the ground, but wine-colored above, rise in imposing beauty and are lost in the evergreen crowns.
The leaves suggest those of laurel, but are broader. The large clusters of white flowers are among the glories of the vegetable kingdom. George B. Sudworth, dendrologist of the United States Forest Service, who usually describes in strictly prosaic terms, breaks away from that habit long enough to compare madrona flowers to lilies of the valley, in his “Forest Trees of the Pacific Slope.” The flowers appear from March to May, depending on latitude and elevation.
The brilliant orange-red fruit ripens in the fall, and is often borne in great abundance. It renders the crowns of the trees very beautiful. The fruit is about half an inch long and contains many small angular seeds. The fruit is said to contain a substance which puts to sleep wild creatures that feed on it. The claim is probably mythical, for birds breakfast extravagantly on it in the morning, and apparently do not do any sleeping until after sunset.
This tree was discovered by and named for Archibald Menzies, a Scotch botanist who traveled in the Northwest more than a hundred years ago. It has several local names, among them being madrove, laurel wood, madrone-tree, laurel, and manzanita. The last is the proper name of another small tree which is associated with madrona and is closely related to it.
The wood weighs 43.95 pounds per cubic foot. It is a little below eastern white oak in fuel value, a little above it in strength, and somewhat under it in stiffness. The color is pale reddish-brown, resembling applewood in tone, but generally not quite so dark. The wood is porous, but the pores are very small. Medullary rays are numerous but thin. On account of the rays being of a little deeper red than the other wood, quarter-sawed stock is handsome and of somewhat peculiar appearance. The figure is much like quarter-sawed beech, but of deeper, more handsome color. The contrast between springwood and summerwood is not strong, though easily seen. Generally, the summerwood constitutes about one-fourth of the annual ring. The tree grows slowly, but with much irregularity. The increase in one season may be four or five times as great as in another. The bark exfoliates, and is quite thin.
Madrona has never been put to much use. Difficulties in seasoning it have stood in the way. The wood warps and checks. Similar difficulties with other woods have been overcome, and such troubles should not be unduly discouraging. The beauty of the wood is unquestioned. It presents a fine appearance when worked into furniture, particularly in small panels and turned work, like spindles, knobs, and small posts. When made into grills it shows a surprising richness of tone. The wood polishes almost to the smoothness of holly. Small quantities are made into flooring; a little goes to the furniture makers; lathes turn some of it for novelties and souvenirs; fuel cutters sell it as cordwood; and tanbark peelers cut the trees for the thin, papery bark. In that case the trunks are left to decay, unless they happen to be convenient to a cordwood market.
One of the most extensive uses for the wood of madrona is for charcoal burning. Blacksmiths buy it because it is cheaper than coal, and some is used in shops where soldering and welding are done; but the most exacting demand comes from gunpowder manufacturers. They find this wood almost equal to alder and willow as a source of charcoal suitable for powder.
Mexican Madrona (Arbutus xalapensis) might properly be called Texas madrona as it occurs in that state and probably in no other, but its range extends southward into Mexico. It produces a poorly shaped trunk seldom much more than twenty feet high and one foot in diameter, and usually divided into several branches near the ground. It blooms in March and ripens its fruit in midsummer. The tree is found on dry limestone hills, and in the valley of the Rio Blanco, and among the Eagle mountains. Cabinet makers in Texas put the wood to rather exacting uses after they have carefully seasoned it to overcome its natural tendency to check. It is very hard; its color is a little lighter than applewood which it resembles; annual rings are scarcely visible, so regular and even is the year’s growth. In Texas the wood is made into plane stocks, tool handles, and mathematical instruments.
Arizona Madrona (Arbutus arizonica) has a restricted range on the Santa Catalina and Santa Rita mountains of southern Arizona, where it ascends to an altitude of 8,000 feet. The species extends southward into Mexico. The largest trees attain a height of fifty feet and a diameter of two. Trunks are usually straight and shapely, and show the thin, red bark common to the genus. The wood resembles that of the species in Texas, and doubtless is suited to the same purposes, but no utilization of it has been reported, except for fuel, and for fences and sheds on mountain ranches. When the region becomes more thickly settled, the value of the wood will be appreciated.
Manzanita (Arctostaphylos manzanita) is not generally welcomed by botanists into the tree class. They say it is too small; but it is as large as some of the laurels which go as trees without question, and is shaped much like them. There are several species of manzanita. The word is Spanish and means “little apple.” The name is natural, for one of the most noticeable things about manzanita is the fruit, the size of well-grown huckleberries. It is shaped like an apple, and its tart taste suggests that fruit. The Digger Indians along the foothills of the Sierra Nevada mountains in California gather the berries by the sack, dry them, and keep them for winter—if they can. It is often impossible to keep them because, like other fruit, they are apt to become wormy. When the Indians discover them in that condition they display rare thrift and economy for savages, by soaking the fruit and pressing out the juice, which is said to pass for a pretty fair quality of cider, but it must be quickly consumed or it will mother and change to vinegar. Indians now put the berries to use less frequently than in early times when they were nearly always hungry.
Manzanita is of the same family as madrona. Its range extends along the mountains of the Pacific coast ranges from Oregon to Mexico, and inland to Utah. The largest trees are about twenty feet high and a foot or less in diameter; very much divided and branched, with limbs crooked in more ways, perhaps, than those of any other representative of the vegetable kingdom. Thousands of canes are cut from the branches, and if any living man ever saw a straight one he failed to report it. Manzanita grows in almost impenetrable thickets on dry slopes and ridges. Its thin foliage casts so pale a shadow that the tree’s shade is little cooler than the boiling sun upon the open naked ground and rocks. The bark is a reddish-chocolate color, and exfoliates in scales of papery thinness. The heart is nearly of the same color as the bark, but the sap is white and very thin. The wood is hard, strong, stiff, but exceedingly brittle. If a branch is sharply bent it will fly into splinters.
The uses of the wood are numerous, but the total quantity demanded is moderate. Novelty stores sell small articles to tourists in California, sometimes passing the wood off as mountain mahogany which does not so much as belong to the same family. The most common articles manufactured by novelty shops from manzanita are canes, paper weights, paper knives, rulers, spoons, napkin rings, curtain rings, cuff buttons, dominos, manicure sticks, jewel boxes, match safes, pin trays, and photo frames.
