University, Lafayette, Ind., 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 remain temporarily at Washington. 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, turpentine, etc., are the principal lines handled by this office. 



TIMBER TESTS, which will have charge of all tests to determine the strength and 

 other mechanical properties of different woods. 



TECHNOLOGY, which will study the microscopic structure of wood, methods of 

 seasoning and drying it, and other problems of a purely technical character. 



MAINTENANCE, which will have charge of the filing and computing, the purchase of 

 supplies, and general care of the entire Laboratory. 



The work in the Laboratory will be of three kinds, as follows: (1) The investigation 

 of problems in experimental research; (2) experimental work in cooperation with com- 

 mercial plants to verify laboratory experiments on a commercial scale; (3) coopera- 

 tion with outside parties for the purpose of assisting them in applying principles and 

 processes of recognized commercial value with which the Service is thoroughly 

 familiar. 



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 collection 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. 



All letters regarding Products work will continue to be addressed to the Forester 

 at Washington. Reply will be made from Washington, if matters of policy are 

 involved. If matters of policy are not involved, reply will be made by the Director 

 of the Laboratory, if the subject refers to experimental work; and by the Chief of 

 the Office of Wood Utilization, if the subject refers to Utilization work.
