Other kinds of grafting wax can, of course, be used, and are usually procurable at the seed stores or made at home, and I have given their composition and the formulas for their manufacture in my work, "The Propagation of Plants;" but, as I have already said, this old standard kind of wax is just as good as any other, although a little more troublesome to use on account of its sticky consistency. Raffia or bass may be employed as ligatures for holding the cions in place, then covered with Leport's or other kinds of liquid grafting wax; but when these are employed it will be necessary to examine the grafted trees frequently, in order to cut the ligatures to prevent girdling. The best implement for grafting is a common broad-blade pocket knife. One with a blade three to three and a half inches long and three-fourths of an inch wide, is a handy size. It should be of the best material for grafting chestnuts, because the wood of this tree is coarse-grained, and so filled with siliceous matter that it soon dulls the keenest blade, and the grafter will, of necessity, have to use his whetstone frequently. In grinding the knife-blade have the sides a true level, from the back to the edge, especially the underside when to be held in the right hand with the edge towards the body. The importance of having a blade of this form will soon become apparent when the grafter attempts to make a true sloping cut on either stock or cion, and it would be well for the novice to practice for an hour or two in splicing some worthless twigs before commencing upon more valuable material, for even an expert workman is very likely to make some awkward dissections and joints when out of practice. The professional propagator of plants may think such details are unimportant, but I wish to impress upon the amateur that in grafting nut trees we are dealing with kinds that will not respond satisfactorily to such free manipulations as the apple and pear; consequently, better and more careful handling is required to insure success. When ready to begin operations in the field, take out a quantity of the shoots to be used for cions, and keep them wrapped in damp cloth or packed in a box, basket or other receptacle with wet moss, to prevent drying. If any considerable number of stocks are to be grafted, then an assistant or two will be required, for the grafter cannot be alternately handling the knife and cions and wax, and do good work, but if he only inserts the cions and his assistant applies the waxed ligatures, the operation will proceed more rapidly and satisfactorily.
