To avoid back splitting, follow the directions for removing large branches in pruning (p. 83). After the stock is prepared, split it along two lines (tigs. 1 and 2), using care to keep the knife in the po- sitions shown, so that as it is driven into the stock it will cut the bark first; if the stock is large, split it along four lines (fig. 3).

. Bulletin. 1901-13. Agriculture; Agriculture. PROPAGATIOX, 67 occur, with great inconvenience to the operator and damage to the tree. To avoid back splitting, follow the directions for removing large branches in pruning (p. 83). After the stock is prepared, split it along two lines (tigs. 1 and 2), using care to keep the knife in the po- sitions shown, so that as it is driven into the stock it will cut the bark first; if the stock is large, split it along four lines (fig. 3). After the baric has been split H to 2 inches deep on both sides of the stock, change the knife to the third position (fig. 4) and complete the cleft. If a horizontal branch to be grafted make IS. the cleft crosswise rather than vertical, so that the scion may be inserted on the side. Scions inserted upon the ujoper face of a branch rarely grow, Avhile those on the sides do quite as well as Avhen placed upon vertical branches. After remov- ing the knife insert a small wedge to hold the cleft open until the edges can be smoothly dressed and the scions inserted (fig. 3). PREPARIXG THE SCIOX. If the scion Avood has been properly selected it will be an easy matter to make two or three suit- able two-bud scions from each of the sticks of scion wood. Where the wood is not uniformly good, select only that which has little ])ith. strong but not large buds, and firm wood. The lower end of Fig. 3.—Cleft grafting: Large stock of Persian wal- nut split to receive four scions. The clefts arc not made entirely across the stock ; i. e., each split is made from one side ouIt. *.
