In order to assist in this part of the operation, a "heel" is sometimes in difficult cases left on a scion, and inserted into a vessel of water, until the union has taken place; or, for the same purpose, the scion is bound round with loose string or linen with one end steeped in water, so as to secure a supply of water to the scion by the capillary attraction of such a bandage. Indeed, the ordinary practice of surroundŽing the scion and stock at the point of contact with a mass Tory Burch Outlet of grafting clay is intended for the same purpose; that is to say, Tory Burch Flats to prevent evaporation from the surface of the scion, and to afford a small supply of moisture; and hence, among other things, the superiority of clay over the plasters, mastics, and cements occasionally employed, which simply arrest perspiraŽtion, and can never assist in communicating aqueous food to" the scion. For the information of those who nevertheless prefer wax to clay, it may be useful to add the two following receipts for making grafting wax. 1, Bees' wax and tallow, equal parts, laid on warm with a painter's brush. 2, Four proportions, by weight, of pitch, four of resin, two of bees' wax, one of hogs' lard, and one of turpentine, melted and well mixed. "When this, or some similar composition, is spread on brown paper, it forms grafting paper, as it is sometimes termed, which, being cut into slips, can be easily applied. Another substitute for grafting clay is sheet India-rubber, cut into narrow strips or bandages, from one-half to three-quarters of an inch broad. The India-rubber is said to present all the requisites sought for in clay; it is air-tight and water-tight, and will not fall away; also it is elastic, which admits of the swelling of the scion in its growth, and it is applied with perfect ease and quickness.

Similar changes take place

Similar changes take place in the sap which is deposited, for analogous purposes, in the bark and wood of the Walnut- tree, during the germination of its buds; and I was led by the discoveries of M. Dutrochet to infer the probability, that the sap during, and subsequent to, its chemical changes, might acquire new and more extensive vital powers. I therefore resolved to suffer the buds of my grafts, and those of the stocks, to which I proposed to apply them, to unfold, and to grow during a week or ten days; then to destroy all the young shoots and foliage, and to graft at a subsequent period. A very severe frost in the morning of the 7th of May saved me the trouble of destroying the young shoots ; but it deranged my experiment, by killing much of the Tory Burch Outlet slender annual wood, wliich I proŽposed to use for grafts; so that I found some difficulty in choosing proper grafts. The swelling of the small, and previously almost invisible, buds, within a few clays enabled me to distinguish the living wood from that which had been killed by the frost, and the stocks were grafted upon the 18th of May. My grafter had more than once been previously employed by me to graft Walnut-trees in various ways, and never Tory Burch Flats having in any degree succeeded, he did not seem at all pleased with the task assigned him, and very confidently foretold that every graft would die: and I subsequently found that he had insured, to some extent, the truth of his prophecy, by having applied grafts which were actually dead. The whole number employed was twenty- eight, and out of these twenty-two grew well; generally very vigorously, many producing shoots of nearly a yard long, and of very great strength; and the length of the longest shoot exceeding a yard and five inches.

The object of this notch is to stop

The object of this notch is to stop a small portion of the ascending sap, in order that it may be absorbed by the scion. In putting on the latter, place it as directed in the preceding ease. 336 CELLULAR SURFACES To all these may be added what has been termed Plug-Grafting. According to Thouin this was used by the Romans in grafting their Olives and Vines, and is mentioned by geoponical writers. The operaŽtion, which is performed in the spring, is as follows: a shoot of the previous year, having one or two eyes, is taken and shaved into a longish cylindrical form, immediately below the lower eye ; a hole two or three inches deep, and as large as the graft, is then bored in the side of the stock ; the graft is placed in this hole, and driven in until it fits it exactly, leaving no space between itself and the stock. If this is done, the libers will be in close contact, and the joining of the graft secure. Some years since this method was revived by a M. Yard, and submitted to the examination Tory Burch Outlet of a French committee, who endeavoured to ascertain whether the plan was likely to be of any importance. M. Vard Tory Burch Flats said it might be used with advantage ; 1st, in filling up with branches the spaces left in pyramids; 2nd, in introducing on lateral branches fruit-spurs, if they, and where they, are absent. As to the first of these uses, the committee remarked that the grafts of last spring resemble fruiting branches more than common branches, which they thought was owing to the almost horizontal position of the graft upon the stock, the ascent of the sap of which is consequently obstructed, and they decidedly preferred side-grafting, heel-grafting, or spur- grafting, whenever possible, if the object aimed at is the filling up the spaces left in pyramids.
