Spring is almost upon us; the dreariness of winter is all but passed away; and the lover of gardens and out-door work may already take up his spade to prepare for the coming season. To many the question is, What trees shall we plant this spring The lover of shade, the admirer of evergreens, those who particularly favor flowers, and others who pay their respects to fruit, are making out their lists. The ignoramus, who has none of these loves or propensities, is about to depend on second-hand information, and to be disappointed in the result. So much has already been written, and by such able pens, on this subject, that an occasional correspondent of the Horticulturist, like myself, feels abashed when he thinks of venturing his own bark on the great waters which are continually surging in books and periodicals, about trees and shrubbery, and grass lawns and flowers. Shall I say it, in all humility, that when I began to learn a little about planting, books failed to enlighten me, because I could not understand what I wanted myself.

This is the case with the majority of those who plant; they begin when they know comparatively nothing about what they actually want My own process was to plant a specimen of every thing in the shape of a tree that I could procure; and such as I did not like, or where they stood too near to each other, I cut down when I got tired of them. I wish I could tell all the pleasure I had in these processes; how I followed this authority as to the proper season: how I dug winter holes: mixed earths of "mold:" "planted not too deep." with the bole standing on a mound, as well as without; what disappointments resulted; and how I have now a forest of all descriptions, of glorious variety; each in its season dispensing its beauties of leaf, fragrance, flower, or fruit. But this would weary the reader, and I will endeavor to be a little practical rather than egotistical, in imitation of the very good example set me by the Editor of the Horticulturist, and his valued correspondents.

First, then, you want shade. If so, plant the Norway Maple; that will give you in a few years, in a good soil, a fine round-headed tree, with a canopy of leaves that defies the sun's penetration, and, in early spring, a glorious display of flowers equal to the Laburnum, and to me more interesting. Here is a shade tree of the first merit bearing flowers; it will satisfy the most fastidious.

When the Tulip tree first bloomed in England, the common people heard that there was an enormous American tree covered with Tulips ! and they opened their eyes in wonderment at the information. It was just after the Tulip mania in Holland and elsewhere. The excitement was great, and the Liriodendron tulipifera was all the fashion. There can scarcely be a handsomer tree, and yet it is not so frequently planted as it deserves to be. It is a good shade tree, but it attains a large size; too large for very small grounds. It is also difficult to remove, having a tap root Procure it, not from the woods, whence it almost always fails; but from a conscientious nurseryman, whom you can believe when he tells you he has moved it at least once himself.

All the Beeches are desirable, and they have no enemies; their picturesque roots are worthy of study from all admirers of nature. There is now a Weeping Beech, of great beauty. But if you want the most beautiful weeper, (next to the Willow,) get the Sophora pendula, which is now coming a little into notice. Apropos of the Willow, (how one rambles when he gets among beautiful trees!) if it had been told us before we ever saw a Weeping Willow, that there was a certain large tree that fell in graceful folds of weeping tresses, like a lady's hair, how far would one not have gone to see it! And, while we are on the subject, let it be remembered that no Weeping Willow tree ever thrived on hard, stubborn ground, that had never been stirred. The best place for it is in deeply worked earth, near to water or a gutter; no better spot can be found than where an artificial bank has been thrown up, say where you have moved your earth to fill a hollow or raise a knoll.

For myself, I am very fond of combining not only beauty of form, and leaf, and flower; but I like to have about me trees which produce something for the children and grand-children to crack or to eat I, therefore, early in my experiments, planted the true Shellbark, the Walnut, the Chestnut, the Butternut, and the Madeira Nut or English Walnut. What more beautiful shade trees can be invented or advertised ? None. Then for products of another kind: all the Crab Apples have great beauty; their flowers are abundant and odorous in the highest degree, and their fruit is invaluable for preserves. The Flowering Apple is really one of the most gorgeous and superb products of nature's laboratory, and may be grafted on the commonest Apple known, may be compared to trees covered with Hyacinths. Alas! neither of these produce fruit As for the Chestnut, it may be well to remark and remember that the finer large kinds of French Chestnuts may be budded or grafted on our native trees; and wherever you already possess these, it is better to do this than to plant anew.

I happen to know a kind of old mortality grafter, who goes all about a certain township in Pennsylvania, begging permission to perform this operation, out of pure love of valuable results.

And why should we not have fruit and shade together! Why is not the shade of a fine Cherry tree as valuable as an Ash ? Believe me, young planter, it is equally so. If you ever enjoyed the delight of getting up into the body of a big Ox Heart or May Duke, when a boy, with free liberty to eat till you were sick, you have reminiscences of which I would not deprive you. Have you ever shaken a Shell-bark Hickory tree, and carried the nuts home on your back in a large grain bag ? Did you ever hull Walnuts, and have black fingers for weeks thereafter, not being aware that soap makes them blacker and vinegar and bran discharges the color ? Did you ever go to wild lands in your neighborhood, and bring home a bag of the red wild Plums ? If you have performed these feats, the first of your knowledge of the pleasures of acquisitiveness, when you plant will you not think of the succession of young and happy hearts that will climb your plantation for a century to come - perhaps your own descendants - and will you not gratify yourself and them by remembering this little list ? I have now in my eye two places in the country where I used to be at home.

The one was so stocked with Cherries, that everybody within miles and miles was at liberty to come with wagons and tubs, and take as many as they wanted; another produced so many Shell-barks that the market sale of them supplied pocket-money for the year to a famous set of youngsters: and these trees were shade trees in every valuable sense.

It would be very easy, now that my pen has caught the inspiration of the subject, to multiply examples,'and to descant on the pleasure of getting two kinds of advantages out of our planting amusements; to increase a list which I have purposely made brief; to descant upon the further amusement of having many varieties of the same kind of fruit on one tree; to say that my best Pears came from new kinds grafted on healthy middle-aged trees of old inferior kinds; and to add that I cultivate some trees and shrubs purposely for the health and attraction of my friends the singing birds, and that few* are better than the Buffalo Berry, the two sexes of which should be "worked "on the same stem.

To conclude, dig large holes for everything like a tree; if in clay soil, burn all the shavings in it you can get, before you plant; drain with stones in a deep bottom (this especially for roses); don't put fresh horse manure to evergreens - rather prefer leaf mold, and that not in too great a proportion; manure your fruit trees with a little guano dug in, in spring and fall; in your Pear orchard it will be better not to have a spear of grass grow near the roots, where however a strawberry bed will thrive well and do no injury whatever. I asked a man, last spring, who was apparently every day among his fruit trees, what he was doing. His answer was, "cultivating;" and this cultivating consisted in stirring the ground, and rooting out every grass and weed root as it appeared, mulching the neighborhood of each tree at the same time, and renewing it as often as needed. That was his first summer in the country; but he will be rewarded as surely as a greenhouse protects tender plants through frosty weather.

The beat fruit garden I ever saw in any part of the world, is on Staten Island, belonging to Samuel T. Jones, Esq., a distinguished merchant of New York. He has Peach trees as large round the stem as a man's body, all trained in the best manner, and producing beyond all calculation. They are examined twice a year for the worm; and besides rich manure and careful cultivation, are treated spring and fall with a double handful of guano mixed with plaster. His Pear trees are perfect gems. Such Vergalieus as he has in profusion, produced last year nine dollars a barrel. The borders of his graperies outside the houses are very large, and always look like a newly raked, deeply dug, and blackly manured, new bed. No spear of grass to be seen in the whole garden. The results such as would inspire the veriest dullard in gardening with a love of the subject Two acres reclaimed from stony ground, furnishing enouga stone to build a thick, high wall around the whole, is brought into perfect cultivation. It does one's heart good to see such care and nicety. I really believe that two acres thus cultivated with head-knowledge and elbow-labor, produces more in actual money value than many a farm of fifty acres that passes in certain neighborhoods for respectable work.

We may see many such a garden in Europe, but how very rarely do we meet with it here. A few years hence we may witness other examples, stimulated by such success.

I hold it to be impossible for a gardener to fully understand his business, and produce the proper effects and results, unless he sees for himself what others have accomplished. An observing visitor never leaves a good garden without having learned something advantageous. At Mr. Jones' he will see the ground very rich, and perhaps come to think that "manure is half a gardener;" he will see every thing in order and in its place; he will, if he asks, learn that the whole garden is dug over in the fall, with as much care as in the spring, and left unraked; and if he don't know it, can ask the reason therefor. One such visit will do more to open a moleish eye than two to a florist's show. Seeing how things are done, is better for a learner than merely seeing the results.
