tion. Data are secured on the forest resources of this 

 and other countries, the effect of timber depletion on 

 industrial and community development, the relation 

 between forest taxation and the practice of forestry, 

 and similar economic problems. 



Grazing Investigations. 



Grazing investigations have to do with improving 

 the forest crop and securing its fullest and best use. 

 Studies are made of artificial and natural reseeding 

 of the range ; of the feed value of the various forage 

 plants, and where they grow ; of the best methods of 

 handling stock on the range ; of water development 

 for stock and the relation between the frequency of 

 watering places and the welfare of the range and the 

 stock ; of the eradication of poisonous plants ; and 

 of the effect of grazing on forest reproduction, on 

 erosion, and on stream flow. 



These investigations are both experimental and 

 general. Experimental work is carried on mainly at 

 the Great Basin Forest Experiment Station on the 

 Manti National Forest in Utah, the Jornada Range 

 Reserve in New Mexico, and the Santa Rita Range 

 Reserve in southern Arizona. The general studies 

 concern the actual management of the range, and are 

 made where particular problems come up in connec- 

 tion with grazing on the National Forests.

The Forest Service does all that it can to put its 

 information at the service of the public and get what

 its results in helpful, practical form, it furnishes in-
