It is truly gratifying to find, in the last number of the Hrrtiecuturist, so correct a view, and such valuable suggestions presented by the editor, in regard to the transplanting of fruit trees. We discover of late an increasing inquiry in relation to this matter; yet I apprehend that much information is still wanting to convince the public mind that a consistent and judicious course of treatment - a course best calculated to preserve a uniform growth of newly planted trees, and to promote their prosperity and vigor through life, - although it may be attended with some extra trouble and expense, will in the end prove most beneficial and satisfactory. The views marked out by the editor are much in accordance with my own. I wish, however, that he had been a little more definite and explicit in regard to deep planting, the construction of the borders, and the component materials to be placed about the roots. Deep planting I conceive to be one of the most fatal errors in forming new plantations; and the most difficult to correct, as the people generally do not seem aware of its injurious effects.

It is not my intention to criticise upon what has been said, and well said, by an experienced Editor, but simply to point out my own experience, and the course I have adopted and. practiced of late years, in relation to the transplanting of fruit trees; and this I will confine to a small orchard of Apple trees, 85 in number, set in the fall of 1851, which was an unusually dry season. thus rendering transplanting more difficult The winter previous, I drew four cart loads of peat earth thrown up from a muck swamp a year previous. This I placed upon the ground prepared for the orchard, and added the same quantity of fine yard manure, mixing the eight loads together for decomposition. Directly after harvest I laid out my ground in diamonds, thirty-five feet apart in the rows. My soil is rather a sandy loam, with gravelly subsoil I then turned up a deep cut back-furrow one way of the rows about six feet wide, as I intended cultivating the ground the coming season. Quite early in the fall I prepared the border for the reception of the trees. The holes were dug four feet wide and two feet deep, carefully placing the surface soil by itself and the subsoil in a separate heap. About the 17th of October I commenced setting the trees.

The holes were about half filled with the partially rotted sods from the back-furrow nicelv placed together. Then the heap of top soil previously thrown out was thoroughly mixed with a portion of the compost heap, at the rate of one cart load to about eleven trees, and the remaining portion of the holes filled with this mixture of fine mold, leaving the mold in the center, where the trees were to be placed, some four or five inches above the level of the surface, and the borders about the same depth below the-surface, leaving the mold to place the roots upon in the form of a little hillock. After smoothly paring off the mutilated roots, the tree was placed upon this little mound, and the roots extended, leaving them in their natural position; then with a shovel the prepared mold was carefully sifted upon the roots, guarding them with the hand during the process. The roots being thinly covered, I then sifted on about two quarts of slaked lime, and the same quantity of wood ashes; then filled up the hole with the remainder of the prepared soil, leaving the top roots at the base of the stem just covered, and these top roots at least four or five inches above the level of the surface, to allow for settling.

This I conceive very essential to the well-being of the tree, that it may at all times receive a sufficiency of light and air. When placed in this position in windy, exposed places, they may require fastening for a time, by a small stake; but this I did not do, with the exception of a few trees. I then placed about the base of the trunk a sufficient quantity of earth or sods to guard the roots during winter; this to be entirely removed the following spring.

In the early part of spring I shortened in the entire tops, taking care to balance the same, and to remove all superfluous branches, leaving from four to six equally arranged on all sides. Instead of mulching in the spring with coarse litter from the yard, as I had previously done, I applied sawdust from the mill, which I found a good substitute, drawing the sawdust from the trees in the fall These trees all lived, and to all appearance scarcely received any check in their growth the ensuing summer, and have continued to grow and flourish beyond my most sanguine expectations, and attract the admiration of those that pass by, especially those who take an interest in horticultural pursuits.

IN your number for this month is an interesting article upon the greenhouses of Messrs. Eaton & Co., Buffalo, with the ground plan, &C. As it is evidently an admirably arranged establishment, that many may perhaps desire to profit by, would it not be well to obtain from them the elevations, that we may see how it looks externally; as also that we may see how to turn the corners at 2 and 6, or 8 and 5, and the mode of uniting the roofs of 2 and 8 with the octagonal conservatory? The total cost of as complete an establishment would also be desirable.*

I do not agree with some of your correspondents that the "Pear subject" is overdone, or that Lepere's pruning" is void of interest to cultivators of the Peach in this country. I, for one, have adopted many of his ideas, not only on my espaliers outside, but also in my fruit-house on Nectarines and Apricots.

While writing, we are threatened with serious injury to the just opening buds of our Grapes in the cold house, from a violent snow storm, with the thermometer already at 30°, and prospect of dropping still lower before morning - (10 o'clock Sunday evening.) The fruit buds of Peaches, Nectarines, Apricots, and Pears outside, I think are not sufficiently developed to receive injury; but the Strawberries, Potatoes, Peas, and other early forced vegetables and fruits that have progressed rapidly the past few days, in their new quarters, will feel the sudden change, and disappoint many an ardent cultivator.
