In recommending this plan to the college authorities, the Forest 

 Service advised them as follows : 



All the planting sites should be broken out and given good tillage 

 for two or three year- prior to the planting of the trees, in order thai 

 the prairie grasses may be subdued. After planting, the ground 

 between the rows of trees should be kept in cultivation as long as 

 possible. During the growing season cultivation should be as fre- 

 quent as once a month. The surface should not be ridged by the 

 cultivator, but should be kept flat. Where the rows are 8 feel apart 

 garden vegetables may be grown between the trees for the first two 

 or three years, since the cultivation of the crops will also serve for the 

 trees. 



The species that should be grown from seed in the nursery and 

 transplanted to a forest site when one or two years old are the fol-
