MISCELLANEOUS DIVISION. 



J. K. HAYWOOD, Chief. 



W. W. SKINNER, Assistant Chief. 



This division and the four laboratories therein were formally 

 organized by the Secretary under date of July 1, 1908, marking the 

 logical growth and expansion of several lines of work, which were 

 originally authorized in the Insecticide and Water Laboratory and 

 reorganized under order of the Secretary, July 1, 1905, as the Mis- 

 cellaneous Laboratory. 



The principal lines of work are the examination, and study of 

 waters, cattle foods, forage crops, grains, insecticides and fungicides, 

 trade wastes, and certain hygienic problems; also such miscellaneous 

 chemical work of the Bureau of Chemistry and of other Bureaus and 

 Divisions of various Departments of the Government as may be 

 referred to this division and which does not properly belong to other 

 established laboratories. For the convenient prosecution of the work 

 the division is organized as follows : 



WATER LABORATORY. 



W. W. SKINNER, Chief. 



The work on waters, originally organized under the Insecticide 

 and Water Laboratory, has been expanded to include the chemical 

 examination and study of mineral waters, irrigating waters, and 

 waters for sanitary, technical, and domestic purposes. A study is 

 being made of mineral waters from source and of the potable and 

 medicinal waters found bottled upon the market for the purpose of 

 securing data for the proper enforcement of the food and drugs act 

 of June 30, 1906. 



The examination of irrigating waters is made in collaboration 

 with the Office of Irrigation Investigations of this Department, 

 while chemical examinations of water supplies for sanitary, technical, 

 and domestic purposes are made when the exigencies of the public 

 service demand the same. 



CATTLE FOOD AND GRAIN INVESTIGATIONS LABORATORY. 



G. L. BIDWELL, Acting Chief. 



To this laboratory are assigned investigations relating to the com- 

 position and nutritive value of feeds and forage crops ; also the exam- 

 ination of commercial feeds for adulteration and the securing of data 

 for the proper enforcement of the food and drugs act. In collabora- 

 tion with the Office of Grain Investigations of the Bureau of Plant 

 Industry, studies are made of the relative food value, milling and 

 baking qualities, and general commercial importance of grams, to- 

 gether with the adaptability of certain grains to specific purposes.
