It is surprising to witness the difference between the growth of trees, and especially the dwarf pear trees, from the effects of mulching the roots. Such trees I have found to have made masses of fibrous roots in a single season, nearly if not quite double to others similarly situated in every respect, but without the mulching.

So long as our tree propagators will determine to grow their trees for market, with long and bare stems five to seven feet high, before heading them in while in the nursery rows, it may be a settled axiom, that such trees will not do without strawing and mulching. Every season proves this in the loss of multitudes of beautiful and apparently thrifty bearing trees, especially among the cherry and peach. A neighboring friend whose cherries have long been the admiration of all observers, from their fine fruit and luxuriant habit, is fast losing his stock from this cause. The bursting and exudation of the gum poisoning the surrounding parts - stopping the pores of the bark below, and forming a mass of flint like substance, which gradually increases until the cellular tissues are entirely blocked up, when the tree dies.

That this malady is produced by the action of the sun, and other external causes, upon the long and naked trunk, there can be no doubt. The outer bark hardens to such amextent, that its expansion, docs not keep pace with the growing tissues beneath - a veat for the over accumulating sap is a necessary result. Strawing or shading the stem will remedy this, as the outer bark is then kept in the same progress of growth as are the inner. The barbarous custom of slitting, will oft times produce relief- - but when cut too deep produces the same disease.
