Though it is little attended to incommon practice, the amateur will beglad to know that the success of a graftis always greatly insured by choosingthe parts so that a bud is left near thetop of the stock, k, Fig. 4, and anothernear the bottom of the scion, I. Thesebuds attract the rising sap to the por-tions where they are placed, fonn woodymatter, and greatly facilitate the union ofthe parts near them; the upper part of PKOPAGATION OF VARIETIES. 21. the stock and the lower part of the scion being the portions soonesiliable to perish from a waut of nourishment.* Cleft-grafting is a very easy though rather clumsy mode, and is inmore common use than any other in the United States. It is chiefljpractised on large stocks, or trees the branchesof ?whicli have been headed back, and are toolarge for tongue-grafting. The head of thestock is first cut over horizontally with the sawand smoothed with a knife. A cleft about twoinches deep is then made in the stock with ahammer and splitting-knife. The scion is nowprepared by sloping its lower end in the form ofa wedge about an inch and a half long, leavingit a little thicker on the outer edge. Openingthe cleft with the splitting-knife, or a smallchisel for that purpose, push the scion carefullydown to its place, fitting its inner bark on oneside to that of one side of the stock. When thestock is lai-ge, it is usual to insert two scions,Fig. 7. On withd
