not been so severely injured as the Black Locust. A sufficient 

 amount of damage has been done to prevent the recommenda- 

 tion of this species for general planting. During the past two 

 years borers have been working on several Honey Locust trees. 

 This attack, however, is not general, but if the borers should 

 continue to spread they will become a serious menace to the 

 growth of one of the best species for planting in western Ne- 

 braska. 



During the first winter freezing killed nearly all of the 

 Osage Orange and Basswood. These species will not endure 

 the severe cold together with the dry weather which usually 

 occurs in winter. It is quite probably that the latter cause is 

 equally as important as the former in preventing a satisfactory 

 growth of these species. Russian Mulberry was killed on the 

 "bench land" but was only slightly frozen back on the "table 

 land." Catalpa and Silver Maple freeze back each year. The 

 injury to these species is sufficient to make them undesirable for 

 general planting. 



Of the twenty species of broadleaf trees which were planted, 

 all showed more than 20 per cent of living trees except the 

 Osage Orange and Basswood. The species which give promise 

 of being most satisfactory for general planting are as follows: 



Among the conifers the results have been generally unsatis- 

 factory. Jack Pine and Western Yellow Pine have made fairly 

 good growth when planted on favorable slopes along the canyon 

 sides. The Jack Pine showed a large percentage of trees surviv-
