Hence the great necessity of growing all plants and trees from the first stage of growth, well, full of health and thriftiness, etc. We shall suppose they hare been well grown in their early stages, and that the trees are properly and permanently planted out as standards; they should now be regularly pruned, the fruit thinned, etc. How this should be performed, has been so well and so frequently described by Mr. Dowy-ijf©, that I shall pass it by. If pruning, thinning, and the other necessaries which the trees require, are neglected, they must of necessity soon perish; if people were but to con-skier the immense draft a heavy crop of peaches must make upon a tree, they would wonder how it was the tree does not die from sheer exhaustion; and if the tree does not perish, it must of necessity become feeble and sickly. I have seen splendid specimens of plants perish after a free bloom, and so well is this known to the exhibitors in England, that many of those magnificent specimens which are shown at Chiswick and Regent's Park, are the day after the show denuded of every bloom.

Now, had all this bloom been allowed to remain and die off naturally, the plants would be so enfeebled, that if they had survived at all, they would require a years' repose before they could be brought out in the same trim, or bloom poorly the following season. It is well known the most delicious frnits are the most delicate, and require the greatest amount of care. The highest bred animals require more care and attention than those of their race of inferior qualities, fa flowers we find it the same. The common Pansy will survive a winter in the northern states, while their cousins, which have been so much improved in size, shape, substance* and color, require the highest state of pot culture in cool pits, in England. Geraniums, as they have been improved by Mr. Beck and others, must have more care than the common old varieties, and those lovely fancy varieties which have come much into culture of late, require still more care, as well as cultural skill, to grow them in anything like perfection. The common clove pink will grow freely in the borders of our flower gardens, but the delicate flaked carnation, and the beautiful yellow picetee, if to be grown well, or at all, must be managed very differently.

And so must our delicious peaches, if we wish the fruit'fine, want to have the trees in health and vigor, and prolong their lives, a good rou-tine of culture must be pursued, or disease will soon manifest itself. It has frequently been urged by excellent writers, to procure the stones from which stocks are raised, from healthy districts, and this cannot be too often recommended, as the good or bad-qualities of the parent will be inherited by the offspring. The growers of oak in England, irreversa bly procure their acorns from the finest trees, and will not use those from small stinted scrubs, and at the present day, many growers procure their Larch seed from Tyrol - the native home of the Larch - in preference to seed raised in Britain. I could run through many other instances of the kind, showing the great necessity of having seed from the healthiest districts. Florists that excel in raising seedling geraniums, pansies, etc., not only save their seed from varieties of first rate qualities, but the individual blooms from which the seed is saved must be as near perfection as possible, and whilst in flower soother bloom of inferior qualities, of that or any other varieties, is allowed to exist, lest the bees may frustrate the object in view, by taking the pollen into the flower which is intended for seeding.

Of no less importance is it, that buds should be taken from a healthy source, as they will assuredly perpetuate and transmit the strength and vigor, or disease of the parent. This holds good through the whole range of the animal and vegetable kingdoms, and is particularly conspicuous in fruit trees, ornamental trees, flowering plants, etc. Hunt's large Tawny Nectarine was raised from thrifty, free growing young plants of the " old Tawny." Most variegated trees, with many of the pendulous, have been produced by accidental branches on trees of their species, produced by sickness, insects, and other causes; yet all these, with the greatest certainty, are perpetuated by budding and grafting. The Mogador (D. P.) Rose is said to be a sport from the Crimson Perpetual, or Du Roi, yet it re-produces itself with certainty by budding, and is more vigorous in growth than the parent. The Clifton White Moss Rose was produced by a sucker from the old Pink Moss; it is the best white moss, but extremely delicate in its habit, and difficult to grow well.

When it does grow well, it is predisposed to sport again, into what is called the Blush Moss. We have another sport in the same line, Unique White Mess, which has been produced by the old Unique Rose - parent and offspring being of the same color, the growth is much about the same, whilst the mossy character of the latter remains constant. In budding or grafting, we perpetuate all the good or bad qualities of the parents, as much, if not more than by seed raised from the latter; all highly cultivated fruits will vary to a considerable extent, whereas, by budding or grafting, we perpetuate them with the greatest accuracy.

It is well known that in England all peaches and nectarines are worked upon plum stocks; the climate being excessively moist, with cool summers, when upon its own stock the tree grows very thriftily; the wood is never matured properly; the autumn finds them full of crude sap, branches, stem and roots, and the following spring the tree will be found in a lamentable state of disease, being one mass of canker, gum and rottenness. To avoid this, recourse is had to the plum stock. And here much judgment and experience is necessary» as varieties of peaches demand peculiar stocks; what are termed French pesetas, are generally worked on what is called the pear plum stock, a variety of slow growth, but one upon which these peaches appear to succeed well; the Muscle plum stock is a variety of muck stronger growth, and on it are worked all the other sorts of peaches, with most nectarines; upon it they grow admirably, though the constitution of the French Peach is such that they will not take upon this stock. Mr. Rivers uses a stock upon which all peaches grow finely.
