 Grafts left in this way are apt to become moldy and fail to make 

 good roots. 



Both these objections are overcome by using the dibble as shown 

 in Fig. 19. When used in this way the dibble is pushed into the 

 ground only once for each graft and there is no possibility of the

Where it is necessary to plant in compact soil or in soil containing

 The grafts are laid against this side and well-pulverized soil shoveled 

 in. If the soil is at all stiff or clayey a couple of inches of sand should
