deciduous varieties should be slightly trimmed back in 

 order to equalize the loss of roots by a ctjrresponding 

 decrease in leaf surface. 



The tree should be set into the tree hole at the same 

 depth that it stood in the nursery. Its roots, exceiit 

 those with a ball of soil around them, 

 should be carefully spread out and good 

 soil worked in among them. Every fine 

 rootlet is thus brought into close contact 

 with the soil. The first few layers of 

 soil should then be added firmly and the 

 last laver allowed to remain loose in 

 order that it may act as a mulch for thv 

 water, which is to lie ji.'ured on freel\ 

 innnediately after the tree is planted.
