 land immediately near, such as a ravine or valley. Hill 

 tops afford the most ideal positions as regards air drainage 

 and if other conditions are satisfactory make excellent lo-

Northern and eastern slopes are regarded as best for 

 apple orchards, owing to the fact that they are slower in 

 warming up in the spring than slopes in other directions. 

 This condition results in retarding the blooming period of 

 trees, and is often sufficient to avoid injury from frost in 

 many seasons. A site facing the direction of the prevail-
