It will bewell to look at them occasionally to see that they do not get toodry nor be so damp as to mold. In the spring when the sap is well up and the trees to begrafted have sprouted and are growing during April and ]\Iay thegrafting should be done. Work may be continued even after thecatkins are out and the leaves half grown. The methods described are those practiced by Mr. George , probably the most successful walnut grafter in thebusiness. 34. Plate One. Tools Used in Walnut GraftingFurnished by Oregon Agricultural College GRAFTING WAX The following formula is the grafting wax used by Mr. Payne: Rosin. 5 pounds. Beeswax, 1 pound. Finely pulverized charcoal, 1-2 pound. Raw linseed oil, 1 gill. Be sure that the charcoal is finely pulverized. First melt thebeeswax and rosin, being careful not to have the fire too hot. Addthe charcoal, stirring constantly, and then add the oil. Mouldinto bricks by pouring into greased pans. When desiring to usebreak off a few lumps and melt in such a contrivance as is shownin the plate of grafting tools. The wax must be quite liquid ifapplied successfully. Nursery grafting, or root grafting, is not a success as practicedat present. The best grafters do not succeed with more than 10to 15 per cent. This makes the grafted tree cost from $ $ per tree, and makes that kind of walnut planting ex-pensive. However, Col. Dosch, in his article, quotes Professor 35
