In most in- stances, the wax will loosen during the first season, and sometimes it falls off. The character of the healing process is well depicted in Figs. 131, 132, 133. In Fig. 131 is shown a yearling graft of apple. The strip of wax along the side of the cleft is seen to have split with the enlargement of the branch, and the cleft has filled up with tissue and is now safe from infection of disease or rot.

This. tissue has not yet covered up the cleft across the end of stub, and this cleft, if posed to the weather, fertile place for the si ing of decay, for it does not unite except along the sides of the stub beneath the bark. When this stub is split through, following the cleft, we may readily distinguish the location of the healing tissues. Fig. 132. The ends of the cions are at e, and they are now simply inactive and nearly lifeless bits of wood. The new or healing tissue has been built up on the outward side of the cions. On the left, this deposition of new tissue may be traced as far down as H, whilst it is thick and heavy at e and above. The whole interior portion of the stub, represented by the dark shad- ing, is dead tissue, which will soon begin a rapid process of.
