which now contains 5,000 reference specimens, and over 10,000 tree- 

 range records were added to those on file. There are now platted 

 525 maps showing tlie distribution of trees by species. 



During tlic year the Forest Service issued 31 new pubhcations, as 

 against 27 the j'ear before. The total number of Forest Service 

 pubhcations distributed was about 245,500, as compared Anth 406,000 

 m the previous 3'ear. During the past two 3'ears the Forest Service 

 has greatl}^ increased the number of its bulletins of a technical char- 

 acter, which are meant particularly for the advancement of scientific 

 work. 



There were 185 public addresses delivered during the year, usually 

 in response to direct requests from organizations interested in tech- 

 nical forestry, from associations of lumbermen or lumber manu- 

 facturers, or from educational bodies or institutions. Exliibits wore 

 made at nine expositions, and four of them were supplemented, at the 

 request of the exposition management, by a series of explanatory 

 lectures. The expositions in which the Service participated were: 

 The Appalachian Exposition, Knoxdlle, Tenn.; the National Corn 

 Exposition, Pittsburgh, Pa.; Kansas State Fair, Hutchinson, Kans.; 

 United States Land and Irrigation Exposition, Chicago, 111.; Land 

 and Irrigation Exposition, Worcester, Mass.; the Alabama Industrial 

 and Agricultural Exposition, Montgomery, Ala.; Arkansas State 

 Fair, Hot Springs, Ark.; and the International Exposition, Turin, 

 Italy. All expenses for the transportation and installation of ma- 

 terial and for travel and subsistence involved in making these exhibits 

 and sending speakers were borne by the exposition authorities or 

 privately contributed, except in the case of the Turin exposition, for 

 which a congressional appropriation had been made. The material 

 used was that on hand as a result either of work done for previous 

 expositions or of the regular laboratory and collection work of the 

 Service. In general, acceptance of requests for public addresses is 

 made conditional on the payment of all expenses involved. 



WORK FOR THE ENSUING YEAR. 



In the foregoing report reference has been made to many investiga- 

 tions and experiments which were in progress at the close of the 

 fiscal year. Some of these are of such a character that the informa- 

 tion sought can be ascertained or the object accomplished within a 

 comparatively short time. In such cases the work will be completed 

 and terminated as rapidly as possible. In many cases, however, the 

 work planned is so comprehensive in character that it must necessarily 

 extend over a considerable period of time. In general, the work for 

 the ensuing year will be along the same lines as that described for 

 the past year. Detailed enumeration of all the investigations under 

 way or planned would so largely traverse ground already covered 

 that specific mention of most of them will not be made. 



The work of bringing about changes in Forest boundaries for which 

 the field investigations were begun in 190S will be brought to com- 

 pletion. There arc still 39 proclamations to be issued before the 

 results of these investigations will have culminated in accordance 

 with the policy outlined in the Ijody of this report. The field work 

 has been completed for nearly all the Forests still remaining, and the 

 reports have been considered and final conclusions reached. The
