Copper labels, to be written on with a stylus, cost 1-1/2 or 2 cents each, according to size. The smaller I consider preferable. I imagined that these would solve the label problem. Picture my disappointment when I found that many of them cracked, or broke off entirely near the eyelet, from flapping in the wind. If they are to be used they must be fastened so as not to move with the wind. Mr. Bixby has an excellent label made on an aluminum strip printing machine. It has a hole in each end and is fastened with a heavy copper wire. He uses two of these labels on each tree. Dr. Morris sometimes uses a heavy wire stake to which he fastens the labels. A good method of attaching labels, and one that does away with the risk of girdling the graft or tree, is to fasten the label to a staple driven into the tree. The matter of labels is a troublesome one for they will get lost no matter what you do. Other conveniences of equipment are a small whetstone, a small hammer, matches, and some volatile oil, like citronella, lavender, wintergreen, or other black fly and mosquito repellant. It is almost suicidal to slap a mosquito on the back of your neck with a keen grafting knife in your hand. A supply of parowax and alcohol for the lantern's sake should be remembered. _Technique_ If the stocks are vigorous and active, and the scions full of vitality, I doubt if the technique is of chief importance, provided it is ordinarily good. However, a good technique will increase the percentage of success. One should have a variety of methods at command for varying conditions of stocks and scions. One may come as near 100% success in grafting hickories as one is able and willing to observe all the known factors of success. I think that we can say now that the factors of success in hickory grafting are known. They are a vigorous and active stock, a scion of abundant vitality, coaptation of the freshly cut cambium layers and prevention of desiccation. The stock and scion have already been considered. How is coadaptation best obtained? One of the best methods, one that can be used in all seasons and in most conditions of stock and scion, is the side graft, the one that Mr. Jones uses in his nursery work. That is the best argument for this graft. It is, perhaps, the simplest, and at the same time one of the most difficult, of all grafts. The scion is cut wedge shaped and pushed into a slanting incision in the side of the stock. Mr. Jones's modified cleft graft is only a side graft made in the top of the stock after cutting it off. The difficulty lies chiefly in cutting the scion and the incision in the stock so that the fit will be perfectly true. This requires practice.
