DRY-LAND EXPERIMENTS 



ject lessons in correct methods of forest 

 planting. In addition the Forest Service, 

 in co-operation with the State educational 

 institutions, State foresters, etc., conducts 

 experiments in nursery practice and field 

 planting in seventeen States. Three of 

 these experiments, located at Belle- 

 fourche, South Dakota, Akron, Colo- 

 rado, and Dalhart, Texas, are in regions 

 where dry-farming is extensively prac- 

 tised. Much useful information on 

 species and cultural methods best adapted 

 to the several States has been secured as a 

 result of these investigations. Such in- 

 formation, of course, is gladly furnished 

 to prospective planters. 



The semi-arid plains of the United 

 States are almost wholly lacking in 

 native timber. With the gradual settle- 

 ment of this region, however, a good deal 

 of planting has been done for protection 

 against wind, for the production of farm
