In the spring when the sap is well up and the trees to be grafted have sprouted and are growing during April and May the grafting should be done. Work may be continued even after the catkins are out and the leaves half grown.
The methods described are those practiced by Mr. George C. Payne, probably the most successful walnut grafter in the business.

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 the beeswax and rosin, being careful not to have the fire too hot. Add the charcoal, stirring constantly, and then add the oil. Mould into bricks by pouring into greased pans. When desiring to use break off a few lumps and melt in such a contrivance as is shown in the plate of grafting tools. The wax must be quite liquid if applied successfully.
