It is encouraging to see that the attention of fruit-growers has at last been diverted from the idea that a gain is to be realized from the purchase of "extra sized trees" at "extra high prices." Common sense and a very little experience ought to be enough to teach any one, that the purchase of such trees cannot be a very safe or very profitable investment, for the following reasons:

First, there is much more labor required and much greater risk attending the removal of such trees than of smaller ones. The roots of a healthy tree extend in proportion to its age and the size of the top, so that a tree with a well-formed top may be supposed to have roots extending many feet beyond its circumference. To dig over all the soil they occupy in the careful manner it should be done, and take them all out uninjured, is a laborious service. Then the risk of removing such large roots without mutilation, is a hazardous one; and the risk of life in a tree after removal, increases in ratio with the size of the tree. And, again, the cost of such trees in nursery, varies in proportion to their size from as much again to four or five times as much as that of younger trees, that can be removed with less difficulty and a better prospect of success.

The imaginary gain in the operation lies in the fact, that it is an 'extra sized tree. Perhaps it is a bearing tree. It may have shown its fruit for one, two, or three seasons. It may be filled with fruit buds when this extra price is paid for it, and may bear, if it lives, in the year of its removal. And then, very likely, it will stop for a season of rest; or rather to give the tree an opportunity to regain its wasted energies, and acquire new roots in the place of the mutilated ones left in the soil of its nativity; and while struggling to regain this loss, how liable to have disease creep in, and, in spite of a struggling effort between the cultivator and the tree, on one part, and the wrong it has had to submit to, on the other, to become a total loss. If this is not the case, circumstances are in favor of its having an injured constitution to battle with for a few years, and then it - poor, heart-smitten, and wronged thing - dies.

The root, we hold to be an important part of a tree; and if once injured it cannot be repaired. Without it no tree can be firmly established in the soil. Nor can it have a healthful growth or thrifty head, unless the roots are perfect.

Suppose two trees, one of "extra size," with the amount of roots ordinarily taken with such trees, and one on the second or third year from the bud, carefully taken up, were set in the same soil and subject to the same treatment; can any one doubt, that in ten years the small tree would far outstrip the larger one in growth, and would possess a healthfulness that the extra size would never know? Would not five years make the small one, at the beginning, the largest and best tree?

We once went with a friend to take up evergreens. He was anxious to take large ones, or those five or six feet high, and was accommodated. We took those from two to three feet high. Both parcels were planted at the same time, in soils equally favorable. Three-fourths of his died, the remainder dwarfed, while ours are now standing, beautifully tall trees, the admiration of all who look upon them.

Where the soil is favorable, we believe that trees almost universally succeed best when they remain where they spring up. Fruit-trees that are casually planted and grow by the sides of fences are much less liable to the invasion of insects than those stunted by frequent removals. Such trees usually have a good soil, made better yearly by the contributions of the winds that drive leaves and other decomposable matter, and lodge around them. Their thrifty growth and smooth bark seem to be somewhat a guarantee against insects and disease. Indeed, self-sowed trees in old fields where the soil is shallow, cold, and moist, will often flourish for a few years. In the end, they grow mossy, insects attack them, and they dwarf and die; because they have too much root, but from the fact that they have not enough soil.

To as, then, the secret of successful tree-growing lies, in the first place, in having a well-prepared soil, deep, well pulverized, and sufficiently dry to throw off all stagnant water. It is much easier to create necessary moisture by stirring the soil, than to get rid of more than is necessary. Into such a soil we would introduce our young trees as early as possible, with all the roots and fibres that promised life and activity, in the full belief, that every year they have passed before their final locating adds so much to the chances against their living, and actually goes to shorten the natural period allowed them for old age.
