plants. It can be employed in grafting 

 on the stem or root. 



A deep oblique incision is made into 

 the root of stem (Fig. 22 [2]). The 

 scion should be about four inches long 

 with the lower end cut wedge-shaped 

 (Fig. 22 [1]). It is then pushed into 

 the incision (Fig. 22 [3]). The union 

 is wrapped with gi'afting cord. It is 

 also well to cover it with grafting w^ax if 

 the union is above the ground. 



Bridge-grafting. — This method of 

 grafting is employed in bridging over or 

 closing up wounds on the trunks of trees. 

 The bark is trimmed off smoothly into the 

 healthy tissue, on each end and side of 

 the wound (Fig. 23 [1]). With a chisel 

 an oblique cut is made into the bark at 

 each end of the wound ; if the wound is 

 large, of course a number of incision? 

 must be made. Cut the scions two inches 

 longer than the length of the wound ;

 each end into the incision at the ends oflFiG. 22— side grafting of plum.

 of the wound should then be 

 firmly wrapped with grafting 

 cloth to hold the scions in 

 place. Instead of grafting 

 cloth any strong cloth may be 

 used, but gi'afting wax should 

 b6 poured over the bandage. 

 The scions will soon unite 

 with the edges of the wound 



and with each other, closing up the entire wound.

Soil. — The soil best adapted to the growing of young trees is one 

 in which there is a considerable amount of clay. Heavy soils are 

 preferable to light sandy ones, though a comparatively light soil with 

 a clay subsoil within ten to twelve inches of the surface gives fair
