SCIENCE 



[N. S. Vol. XXX. No. 775 



is to cost approximately $50,000, is now in 

 the course of construction. The laboratory 

 will be a fire-proof building of brick trimmed 

 in white stone and is located near the Chi- 

 cago, Milwaukee & St. Paul Eailroad, with 

 exclusive tracks and other railroad facilities. 

 The building is expected to be ready for oc- 

 cupancy upon January 1. In the meanwhile 

 temporary oiBces will be provided. 



On October 1 the Yale Timber Testing 

 Laboratory was discontinued and the forest 

 service equipment there shipped to Madison. 

 The laboratory at Washington was discon- 

 tinued at the same time. The Timber Test- 

 ing Laboratory at Purdue, Indiana, will be 

 operated until the middle of December when 

 it will be discontinued and its equipment 

 shipped to Madison. 



The offices having general supervision over 

 all the work of the branch of products will re- 

 main temporarily in Washington. W. L. 

 Hall, assistant forester, continues in charge 

 of Branch of Products and McGarvey Cline 

 will be director of the Madison Laboratory. 

 The work of the laboratory will be assigned 

 to five offices, as follows: 



Wood Preservation, which will study all 

 problems related to the impregnation of wood 

 with preservatives and other substances. 



Wood Chemistry, which will handle all 

 work bearing on the chemical utilization of 

 forest products. Wood distillation, paper 

 pulp and other fiber products, chemical 

 analyses of creosotes, turpentines, etc., are the 

 principal lines handled by this office. 



Timber Tests, which will have charge of all 

 tests to determine the strength and other me- 

 chanical properties of different woods. 



Technology, which will study the micro- 

 scopic structure of wood, methods of season- 

 ing and drying it, and other problems of a 

 purely technical character. 



Maintenance, which will have charge of the 

 fi-ling and computing. It will also be respon- 

 sible for the purchase of supplies and general 

 care of the entire laboratory. 



The class of work in the laboratory may be 

 separated into three kinds, as follows : 



1. The investigation of problems in experi- 

 mental research. 



2. Experimental work in cooperation with 

 commercial plants to verify laboratory ex- 

 periments on a commercial scale. 



3. Cooperation with outside parties for the 

 purpose of assisting them in applying prin- 

 ciples and processes of recognized commercial 

 value with which the service is thoroughly 

 familiar. 



The supervisory staff of the laboratory is as 

 follows : 



McGarvey Clhie, Director. 

 H. S. Bristol, in charge of Wood Chemistry. 

 H. D. Tiemann, in charge of Technology. 

 H. F. Weiss, in charge of Wood Preservation. 

 Rolf Thelen, in charge Timber Tests. 

 W. H. Kempfer, in charge of Maintenance. 

 The technical force will in part be made up 

 of the following men : 



H. E. Surface, engineer in wood chemistry. 

 Edwin Sutermeister, wood pulp investigations. 

 Jason L. Merrill, chemist. 



E. Bateman, chemist. 



L. P. Hawley, wood distillation investigations. 

 Frederick Dunlap, kiln drying investigations. 

 C. D. Mell, microscopist. 

 W. D. Brush, microscopist. 



C. J. Humphrey, pathologist, detailed from the 

 Bureau of Plant Industry. 



F. W. Bond, mechanical engineer. 

 E. W. Ford, mechanical engineer. 

 C. T. Barnum, mechanical engineer. 

 C. P. Winslow, civil engineer. 



The work of the office of wood utilization 

 at Chicago will consist of studies of the 

 wood-using industries of various states, the 

 study of woods in manufacture and of the 

 methods of disposing of mill waste, the col- 

 lection of statistics on the price of lumber at 

 the mill and at the principal distributing 

 markets of the country, and the study of 

 specifications and grading rules. The office 

 will also secure statistics of forest products 

 of importance to the experimental work of the 

 service and the study of the movements of 

 lumber and of the conditions of the principal 

 lumber markets. 



The personnel of the office of wood utiliza- 

 tion for the present is as follows : 



H. S. Saokett, in charge. 

 Hu Maxwell.
