carbons for each. The Bureau of Plant Industry will also reply in triplicate through 

 the Forester. When there is a consulting pathologist in the District, correspondence 

 between him and the supervisor should be carried on through the District Forester, 

 with carbons of all important letters for the District Forester, the Forester, and the 

 Bureau of Plant Industry. 



Correspondence relating to protection from birds, rodents and other animals, 

 which is intended for the Biological Survey, should be transmitted by the supervisor 

 through the District Forester and Forester, with carbons for each. Replies from 

 the Biological Survey will be in triplicate through the Forester and District Forester, 

 each of whom will retain a carbon of the reply. 

 Nursery Reports 



Experiments and investigations at the various Forest Service nurseries often lead 

 to results which would be of particular interest and value to other nurseries. In 

 order that information of this character may be made generally available, it is sug- 

 gested that the progress reports for all the nurseries in each District be briefly sum- 

 marized in the District office and a sufficient number of mimeographed copies of this 

 summary be sent to eafh District Forester for optional distribution to Forest nurs- 

 eries within each District. Summaries of these reports for general distribution should 

 be made as brief as possible and should include only results of experiments in nursery 

 practice that are distinctly of general interest. Such summaries need not necessarily 

 be made each month, but as often as nursery reports contain sufficient information 

 to justify the expense of compilation. 

 To Increase the Usefulness of the Library- 

 It is the aim of the Library Committee to include in the Washington library all 

 books on forestry which might be of any use in this country, and also books on other 

 related subjects which would be frequently referred to by members of the Service . 

 It will help the committee greatly in securing all desirable literature of either of 

 these classes if members of the Service, both in the field and in Washington, will 

 notify the committee at once of new publications which they believe should be in- 

 cluded, with the reasons for their recommendation. The value and usefulness of the 

 library can also be increased by notifying the librarian of special articles of interest 

 in periodicals which are not already catalogued, in order that they may be included 

 in the library index. A monthly list of accessions to the library reprinted from 

 American Forestry is sent regularly to each District. Publications in the Wash- 

 ington library can be borrowed at any time by field men, for periods of not more 

 than one month, by applying to the Forester through the District Forester. 



GRAZING 

 Grazing Permits and Trespass Period 



In several cases of grazing trespass, which have been received in the Forester's office 

 during the past season, it has been found that supervisors have issued grazing per- 

 mits which were for periods covering a part or all of the period during which the 

 stock were grazed upon the National Forest in trespass. It is the opinion of the 

 Solicitor that the issuance of a permit of this character is a condonation of the tres- 

 pass by the Forest Service, which renders it difficult, if not impossible, to sustain
