84 JUNE EFFECTS ON THE LA WN. 



variety of coloring and conformation on individual speci- 

 mens, hence it follows that careful selection of the best 

 varieties and their strict perpetuation by grafting become 

 important to the lawn planter. 



The Cephalouian fir, Abies Cephalonica, is another at- 

 tractive evergreen in June, although now and then it 

 suffers from hard winters. 



Abies Parsoniana or lasiocarpa is one of the rarest and 

 finest species of the genus, and its long, curled, light- 

 colored leaves assume the richest hues in early summer. 



Abies concolor is another excellent and similar ever- 

 green. 



It is an important fact to remember that systematic 

 pruning of both the leader or topmost twig and of the 

 side branches of these silver firs tends greatly to develop 

 the beautiful June growth on every part of the tree. It is 

 not well, however, to continue this pinching too long or too 

 frequently, for the tree may thus come to lose the essential 

 characteristic form of the species or variety. 



Very attractive also are the early tints of the dark and 

 extremely attractive dwarf Hudson's Bay fir, as well as 

 those of the neat and elegant Abies pectincita compacta. 

 These last-named forms may be classed among the hardiest 

 of evergreens. Turning to several evergreens which are 

 almost unknown on the lawn and that are at the same time 

 attractive in June, we find the hardy form of Abies Douglasii 

 or pseudotsuga Douglasii. The particular variety of the 

 Douglas spruce generally employed has been found some- 

 what tender in the Eastern or Atlantic States, apparently 

 because most specimens have been brought from the lower
