Don't let the wounds of the scion or stub remain exposed longer than necessary. Make the cuts smooth with a very sharp knife, kept sharp by frequent "stropping.'" Expert walnut grafters are few, but the ordinary skillful orchardist or amateur can do fairly successful work by a study of the drawings in "Details of Walnut Grafting" on next page, and using common sense methods. [Illustration: Details of Walnut Grafting] Cut off the branch or stock to be grafted with a sharp priming saw at a point where the stump will be from one to two and a half inches in diameter. Split through the center of the stub with a sharp knife as shown in figure 1, using a mallet. Depress the point of the splitting knife and strike with the mallet, cutting the bark and sap down the side of the stub instead of tearing it, then depress the handle and cut down the other side in the same way. Open the split slightly with a hardwood wedge, as in figure 2. Slightly bevel the split, cutting upward, with a sharp knife as in figure 3. Insert the carefully fitted scion as at figure 4, being careful to have the cambium layer, the inner layer of the bark, of both stub and scion come together. When the scion is carefully fitted remove the wedge and fill the split with paper as shown at figure 5. Then cover all wounds over with wax brushed on warm as at figure 6. The melted wax should be about the consistency of thick honey. Tie a paper sack over all as at figure 7. This should remain until scions begin to grow. It keeps them warm and prevents drying out by hot winds. In from ten days to three weeks the scions will have started sufficient to gradually remove the cover as at figure 8. In eight or ten days from the time grafts are set a small opening should be cut or torn in the north side of the paper sack so that the sprouting buds may have air and their growth noted. When the stock is too large to split through the center it should be split to one side of center as shown in figure 9. The method of shaping the scions is shown in figures 10, 11 and 12. Good scions and poor are shown in 13 and 14. Scions with buds not too far apart are best. Prong grafting is shown in figures 15 to 18, and flute budding in 19 and 20. In grafting the stock should not close on the scion with sufficient force to bruise or injure it, but just tight enough to hold. Scions should be of last year's wood and pruned or cut from the trees in late winter, when the tree is dorma
