50 Forest Club Annual 



in the fall of 1906. The following spring it was disced an.t 

 harrowed before planting was commenced. The land which 

 was planted in the canyons was not ploughed. 



The stock which was planted was the best that could be 

 obtained. Some of it, however, arrived in poor condition due 

 to improper packing or to delay in transit. The broadleaf spe- 

 cies were all one year old seedlings with the exception of the 

 Cottonwood, Norway Poplar and Carolina Poplar which were 

 one year old rooted cuttings. The Conifers were all three year 

 transplants. 



Two methods of planting were used, the slit method and the 

 hole method. In the former method a spade was pushed into 

 the ground leaving a narrow slit-like opening into which the 

 plant was placed. The ground was then packed closely around 

 the roots. In the latter method a hole was dug large enough to 

 hold all of the roots without crowding them. The soil was then 

 made firm about the roots. 



Some of the trees developed forks and others produced 

 many lateral branches. One of the forks was removed in all 

 cases where it was possible to improve the tree. The larger lat- 

 eral branches were also removed in order to allow the trees to 

 develop better boles and also to permit cultivation. 



The trees are still too young to show any decided results 

 of different spacing distances and mixtures of species. It is 

 quite probable that it will require at least ten years to show any 

 decided difference in growth. 



Some species have been subjected to injuries from gophers, 

 cottontail rabbits, borers, freezing and winter drought. Gophers 

 injured about twenty-five per cent of the Silver Maple during 

 the first winter. Nearly all of the Honey Locust seedlings were 

 cut off during the same period. The damage from gophers 

 since that time has been slight. Cottontail rabbits did some 

 damage to the Honey Locust seedlings by nibbling off the bark. 

 Sprouts started at the bases of the young trees which were in- 

 jured. Since that time no further injury has been observed. 



Borers have attacked the Black Locust, Green Ash, and 

 Honey Locust. Black Lucust Borers have succeeded in weaken- 

 ing the trees until nearly all of them have been blown over by 

 the wind. The trees have made excellent growth and would 

 be a most desirable species, since it will occupy almost any kind 

 of soil, were it not for this most serious enemy. A large per 

 centage of the Green Ash have been attacked by borers but have
