14 Growing Forest Trees in Western Nebraska 



TABLE 2. Species and number of each planted on tilled land, in 

 the spring of 1908. with the percentage of stand in the -fall 

 following. 



BENCH LAND. 



* Failure of Carolina Poplar and the low percentage of Norway Poplar 

 are due to the stock of both varieties being fresh cuttings when planted. 



t Low percentage of American Elm due to poor condition of trees when 

 planted. 



CULTIVATION. 



The trees have been given clean tillage. This has required 

 the use of a one-horse cultivator and occasionally the hoe. Some 

 groups of trees now shade the ground so thoroly after they are 

 clothed in their summer foliage that no cultivation is required 

 during the latter part of the summer. We see need of continu 

 ing the cultivation only when it is necessary to keep grass or 

 weeds from growing 



PRUNING. 



We have pruned the trees each spring to prevent the forma- 

 tion of forks that would later result in splitting the main trunk 

 of the tree, and to eliminate side branches that interfered with 

 cultivation. Some catalpas have been cut back to the ground. 

 The new shoots from these, in most cases, have frozen back dur- 

 ing the first winter after their growth. 



SPACING AND MIXTURES. 



Neither the planting of trees different distances apart nor 

 planting different species together has given any very decider!
