deciduous kinds and are consequently lifted from the 

 nursery with a ball of soil around the roots. All bruised 

 roots should be cut off and the crown of the tree of the 

 deciduous varieties should be slightly trimmed back in 

 order to equalize the loss of roots by a corresponding 

 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, except 

 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 layer allowed to remain loose in 

 order that it may act as a mulch for th'.^ 

 water, which is to be poured on freely 

 immediately after the tree is planted. 



WHAT TO PLANT 



The choice of material will vary with 

 the general region of the country and 

 the local moisture, soil and atmospheric 

 conditions, as well as with the particu- 

 lar aesthetic effect in the mind of the 

 planter. Xo brief list of plants, given 

 here, can, therefore, presume to be either 

 complete or meet all the requirements of 

 every reader. The only purpose a list 

 like that can serve is by way of sugges- 

 tion to show, at least for the Eastern 

 States, a few of the species that arc 

 generally considered worth planting
