fat 
in chipping. In connection with this investigation a study is being 
made, in cooperation with the chemical department of the University 
of North Carolina, of the characteristics of turpentines yielded by 
native timber pines. . 
A series of important publications in course of preparation will 
describe and illustrate the tree species of the different regions of the 
United States. The first of these bulletins to be ready will embrace 
the trees of the Pacific coast, and the second those of the Rocky 
Mountain States. One special use of these tree books will be the 
aid which they will give Forest officers on National Forests in identify- 
ing species and in acquainting themselves with their habits, growth, 
distribution, and other important facts. 
The dendrologist also gives technical information about trees, in 
response to inquiries, including the identification of the wood, seeds, 
foliage, etc., of native and exotic trees. A large and growing cor- 
respondence evidences the public demand for such information. 
The Government forest exhibits prepared for State, National, and 
international expositions explain what forestry is and show its appli- 
cation to the problems with which the Service is dealing. Through 
these displays much public interest is aroused and information given 
concerning our forests, their economic importance, and right and 
wrong methods of using them. 
INSPECTION. 
It is the policy of the Forest Service to maintain a thorough system 
of inspection of its own work. There are about twenty-five inspectors, 
charged with oversight of all the activities of the Service, both on the 
National Forests and elsewhere. It is the duty of the inspectors to 
see exactly what work is being done and how it is being done, and to 
advise with all those in charge of projects or having administrative 
authority in National Forests. They are not, however, themselves 
authorized to issue orders. Their reports are made directly to the 
Forester. 
There are six inspection districts, each in charge of a chief in- 
spector. These districts are: 
District 1. Montana, northern Wyoming, and northern Idaho. 
District 2. Colorado, southeastern Utah, Nebraska, South Dakota, 
Kansas, southern Wyoming, and southeastern Montana. 
District 3. Arizona, New Mexico, and Oklahoma. 
District 4. Utah, southern Idaho, eastern Nevada, western Wyoming, 
and northern Arizona. 
District 5. California and western Nevada. 
District 6. Washington, Oregon, and Alaska.
