 results of a detailed study of the Rio Pueblo and Rio Santa Barbara watersheds 

 of the Santa Fe National Forest. The object was to determine the class of 

 product, rotation, and cutting cycle to be used in the future silvicultural 

 management of these and similar areas. It is concluded in substance that 

 economic conditions in these areas warrant the use of a short rotation sufficient 

 for the production of hewn ties rather than a long rotation for the production 

 of saw timber. A short rotation is also considered more desirable from the 

 pathological standpoint.

 at the rate of 5,584 trees to the acre. Tree removals were begun in 1913, when 

 the largest trees were taken out. During this period the loss in area was
