books will deal with the trees of the Soutiaern and Atlantic States. 

 The characteristics by which tree planters ma}" recognize the different 

 species of catalpas will be described in a special publication. 



The dendrologist also gives technical information about trees in 

 response to inquiries. A large and growing correspondence evidences 

 the public demand for such information. 



The Service has a photograph collection containing about 20,000 

 photographs and nearly 3,000 lantern slides, illustrating forests of the 

 United States and foreign countries. 



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. 



GRAZING. 



This office has charge of grazing on ranges in forest reserves. The 

 grazing of cattle and horses and the grazing of sheep and goats are 

 separately handled. There is also a section of inspection. 



The live-stock interests on reserves are now very great. In the 

 past much difficulty has arisen over the equitable use of the range. 

 The present system of charging a reasonable fee for all live stock, 

 which was inaugurated at the beginning of 1906, has already been cor- 

 dially welcomed by live-stock owners. By paying for the right to use 

 the range these owners benefit both by avoiding all cause of dispute 

 and by the protection which the Forest Service gives in consideration 

 of the charge. Opposition to the system of fees has ceased. Fines 

 for trespass or for understatement of the number of the stock have 

 been promptly paid, and not a single suit against the Government has 

 been brought on the score of dissatisfaction with the ruling of the 

 Forester. During the first six months of 1906 the revenue from 

 grazing was over $500,000. 



Amonof the matters which must be decided in the management of 

 this office are, what number of stock shall be allowed to graze, what 

 portions of reserves shall be open to grazing, the period during' which 

 grazing is allowed, the fees to be charged for permits, the settlement 

 of controversies, the examination of title to private lands, the estab- 

 lishment of driveways for live stock, settlements for damages, and 

 the formulation of special rules to meet local conditions. By coopera- 

 tion with live stock associations through their advisory boards a con- 

 stant good understanding of rights and duties is made possible between 

 stock owners and the Forest Service. 



The section of inspection investigates range conditions and contro- 

 versies, studies and recommends the proper division of the range, and 

 checks gra^dng accounts of forest officers.
