Wherever there are any Holland bulbs remaining unplanted, have them put in as soon as possible, lest frost should set in. It is not advisable to keep them later out of the ground than the beginning of this month.

PROTECTION OF CHOICE BULBS.

On the appearance of the severity of winter, the finer sorts of these should have a simple protection, not because they will not do without such care, but to prevent the alternate thawing and freezing of the embryo of the bulb. To give them a covering three inches deep of any of the following substances, will do perfectly well,—saw-dust not resinous, old tan bark, half decayed leaves, or very rotten manure. The last is preferable, as it would in part enrich the soil.

AnemÒnes and Ranunculus ought to be protected by a frame; the foliage being above ground, none of the above will answer. It is not necessary that the frame should be covered with glass, close boards will answer perfectly, which must not be over them except during frost.

TUBEROSES, DAHLIAS, TIGRIDIAS, AND AMARYLLIS.

These tubers and bulbs, as soon as the frost has partly injured the foliage, should be taken up, and dried thoroughly, either in the sun or a room where there is fire heat, taking care at all times to keep them clear from frost. When they are dry, divest them of their foliage and fibres. When perfectly dry, pack them in boxes with dry sand, or moss. Store these away for the winter, either in a warm room or a dry cellar, where they will at all times be exempt from frost, the least touch of which would destroy them. We have kept them completely secure in the cellar.

ERYTHRINAS.

Where there are any plants of E. herbÀcea, E. laurifÒlia, or E. crÍsta-gÁlla, which are intended to be lifted, they should be carefully done and preserved in half dry earth, and kept beside the DÁhlias. We are not sure of the former agreeing with this treatment, but certain of the others, which are magnificent ornaments in the Flower-garden.

PRIMROSES, POLYANTHUS, AND DAISIES,

That were planted in a sheltered spot, as directed last month, should have a frame placed over them, and their covering in readiness for the approach of winter; giving the plants a light covering of leaves, which will preserve their foliage from the effects of frost.

CHOICE CARNATIONS, PINKS, AND AURICULAS,

That are in pots, should be placed in the frame intended for their abode during winter. If the pots are plunged to the rims in tan, half decayed leaves, or saw dust, it will greatly protect their roots from the severe effects of frost. Where glass is used for these frames, they should have besides a covering of boards, or straw mats; those that are in beds may be covered as above directed for Primroses, &c.

They ought not to be uncovered while in a frozen state. It is not altogether the intensity of cold that destroys these plants so much as the alternate thawing and freezing.

All half hardy plants, such as Wall-flower, German stocks, Sweet-bay, tender roses, with several others, should be protected as above directed for Carnations. Earth or tan should be put round the outside of these frames, which will be a partial shelter from the changing state of the atmosphere. Oak leaves answer the purpose very well, but they are a harbour for all kinds of vermin, especially rats and mice, which would destroy every thing. It may be useful to say a few words on the nature of tan or tanner's bark. Many suppose that the smallest quantity will produce heat, If three or four cart loads of it are put into one heap, and protected from the rain, it will ferment; and when the first fermentation is abated, by mixing it with leaves, a substantial hot-bed may be made. Or put it by itself into a pit, and where there is no pit, boards may be substituted to keep it together; either of these methods will produce a lasting heat. But in small quantities and exposed to rain, &c. no heat will be produced, but rather the contrary. It is excellent when dry in keeping out frost from any plants, being a body not easily penetrated, similar to dry sand, saw-dust, or dry leaves. Frequently the same opinion is held in regard to stable manure, small portions of which will never produce heat.

OF PROTECTING PLANTS IN THE GARDEN.

During this or next month, according to the state of the season, protect all the plants that are in the ground, which are not completely hardy. To avoid repetition, these will be designated in the general list. The coverings may be straw, Russia mats, canvass, boxes or barrels. The two latter must be perforated in the top, to let the damp air pass off, or the plant would become musty, or finally mortify. Those covered with straw or mats should have small stakes placed round the plants, and covering tied thereto, and remain so until the month of March or first of April. Herbaceous plants that are tender, may be covered with three or four inches of tan, saw-dust, or half decayed leaves, which will tend greatly to preserve their roots. These coverings must be carefully removed on the first opening of spring. The shrubs that are otherwise covered would be greatly benefited by having their roots protected in a similar manner as directed for herbaceous plants.

PROTECTION OF SEEDLING BULBS.

If any seeds of Hyacinths, Tulips, FritillÀria, were sown in pots or boxes, let them be removed to a dry sheltered situation, and plunged level with the ground; or fill the spaces between them with dry leaves or tanner's bark, and cover the whole with new fallen leaves, laying over all a few boards to prevent the wind blowing them off. These form better coverings than straw or haulm, which is liable to become musty, and communicate the effect to the roots. The above covering is not required until the approach of severe frost.

OF PLANTING DECIDUOUS TREES AND SHRUBS.

It is not recommendable to make a general planting of these at this period of the year; the success entirely depending on the nature of the season and the state of the soil. If any are planted, let them be those of the hardiest nature, and in light and absorbent soil, not subject to be stagnated or over-flooded during winter. When this and next month are mild, autumn plantings are frequently as sure as those of the spring. But the precarious state of the seasons is not to be depended upon, therefore avoid largo plantings of any kind, and more especially of delicate roses, the roots of which are apt to rot off except they have been previously grown in pots. Nothing can be more injurious to a plant at this season particularly, than to bed its roots in mortar, by which the tender fibres either perish or are cramped ever afterwards. The soil at time of planting should be so friable as not to adhere to the spade, which is a good rule in planting at any season, or in any soil.

GENERAL OBSERVATIONS.

Carry out of the garden all decayed leaves and litter of every description, cutting down any weeds that remain. Collect all the stakes and rods that have been supporting plants; tie them up in bundles for the use of next year, and put them under cover. Look over every part of the garden, and see that nothing has been omitted in the way of covering or other protection. The sashes that are to be used on the frames should be perfectly whole, every interstice in the glass puttied, and all ready for use when occasion may require. Attend to all plants in pots, and give them gentle waterings as they stand in need; but never during the time the soil is frozen about their roots.
