Dear SIR; One year ago, a friend of mine presented me with one hundred dwarf pear-trees from the Rochester Nurseries, and, although their roots were unfeelingly lacerated by careless hands, they brought forth some fruit the first year, The donation innoculated me with the dwarf tree fever; each tree became an acquaintance and a particular object of ray care. This year, they have been mostly barren, although they have made a fine growth of wood. As horticultural science has become a little deity that perches, in these modern days, on every bash in everybody's garden, I coaxed up an acquaintance with bis little excellency, and introduced him to each tree, and, after reading Mons. Cappe's mode of pruning and pinching, I went at it in season, and nipped, with great care, every little protruding twig except the leader. And now my astonishment has been very pleasantly awakened, by discovering very many of the twigs so pinched as aforesaid, crowned with a beautiful fruit bud, an event which I had no faith in, and the Lilliputians make bragging promises of giant burdens the ensuing year.

I wrote to Col. Wilder, of Boston, for advice in planting, and that gentleman, though a stranger, kindly gave me his advice, for which I shall be ever grateful, for a friend of mine, who has some three thousand trees, planted his own way, has lost numbers of them this year by the borer. I advise him to take them all up and replant, or I believe he will lose the whole.

1st Question

I have a quantity of young plum-trees large enough to bear thriftily in very heavy soil. Can I graft peaches successfully on them? I have grafted nectarines on plum with uniform success. Will the peach do as well 1

2d

Salt, science says, is a good fertilizer for quince. Would you, therefore, recommend salt for dwarf pear-trees on quince roots?

3d

I have seen somewhere a remedy for rose-bugs in which I had faith, but have forgotten it, and cannot find it. Do you know what will keep them away? They were very destructive, last year, upon grapes.

4th

The apple-tree borer kills our trees, and bores our patience. I have about lost an orchard of sixteen years' standing. Is there any remedy f or must we bear the loss?

It is wonderful to me, when I reflect upon it, notwithstanding the much noise, of late, about horticulture, that there is so little attention paid to it. A garden is a little world of pleasures and delights, yet locked against thousands standing outside who know nothing of the pleasures inviting them within.. As time flies on, earlier acquaintances scatter, old friendships are broken, the promises and hopes of youthful days drop and fade as years pile up their burdens and infirmities upon the waning strength of age, and, before we are aware, we stand in the midst of a bustling, fluttering world, solitary and alone. If we go upon the highway, it is filled with strangers; if we stay at home, our visitors belong mostly to another generation; if we visit the usual place of public worship, the whole countenance of the congregation scarcely resembles what we remember it to have been in time gone by. Now, if we have a garden of our own planting, we recognize an acquaintance in every tree, and vine, and shrub, and, with a little effort of the imagination, every plant becomes personified, and thus the plantation is an interesting family, smiling at our approach, and gratefully contributing their luscious fruits as if to reward us for our care.

Every one, who can, should plant a garden, cultivate a taste for it, read the Horticulturist, and learn, amid trees, shrubbery, and flowers, to be a happier man.

[1. Peaches do better on plum stocks than on their own roots; they are more productive, and live longer.

2. Salt, in small quantities, is advantageous to the quince, or the pear on quince stocks, when they are growing in a light soil. When the soil is wet or heavy, salt is injurious.

3. Quite a variety of insects go under the name of rose-bugs, in different parts of the country. In the open air, we know of nothing better to destroy them than occasional syringings with water in which tobacco has been well soaked.

4. Gas tar will prevent the borer from entering the trees. Tar around the tree from the surface of the ground to an inch or so below; when applied much above the surface, it is said to be injurious. When the insect has already taken possession, wire may be ran into their boles, to dislodge them, and many may be destroyed by digging away the soil from the collar of the tree in the fall, so that the frost may be better able to enter the holes. Some have had good success with the last plan.]
