with the wintering of bees. This work was undertaken in coopera- 

 tion with the Bureau of Entomology. 



To furnish reliable data on which to base the recipes and practi- 

 cal suggestions published by the office, a laboratory kitchen was in- 

 stalled. Here methods of using food substitutes are tested, stand- 

 ard recipes are worked out, and much-needed information gathered 

 regarding the chemistry and physics of cooking processes. In part 

 of this work the Food Administration has cooperated. A demon- 

 stration kitchen has also been equipped in cooperation with the 

 offices of extension work, which will afford opportunity for demon- 

 strating to field agents the results of the department's experimental 

 work and give them an opportunity to practice the different phases 

 of extension teaching in home economics before undertaking the 

 work in the field. 



In addition to the cooperation with the Bureau of Chemistry (in 

 problems relating to canning, drying, and salt-pickling foods, and 

 the use of such products in the home). Bureau of Plant Industry, 

 Bureau of Markets, Bureau of Entomolog}', and the War Depart- 

 ment, the year has been characterized by cooperation with the Food 

 Administration and with the Woman's Committee of the Council 

 of National Defense, a member of the office staff having been espe- 

 cially appointed to serve with that committee as executive chairman 

 of its department of food production and home economics. 



The office cooperated with the Food Administration and the Bu- 

 reau of Education in the preparation of four courses of instruction 

 on food in the war emergency situation, designed particularly for 

 women students in colleges and universities. Each course has in- 

 cluded 13 lessons. In addition, a book entitled " Food Guide for 

 War Service at Home" has been prepared for publication, which 

 summarizes some of the more important subject matter of the les- 

 sons. The office also cooperated with the Food Administration and 

 the Woman's Committee of the Council of National Defense in the 

 preparation of a pamphlet entitled " The Day's Food in War and 

 Peace," which includes 9 lessons on food topics. It is designed 

 for the use of women's clubs and other organizations, each lesson 

 including a discussion of the subject matter, suggestions for a 

 demonstration with recipes for the use of the materials discussed, 

 references to Government publications and to lantern slides pre- 

 pared by the Department of Agriculture and the Food Adminis- 

 tration. 



The work with clothing, household textiles, and household equip- 

 ment was continued, particularly with reference to the preparation 

 of bulletins and other material on methods of handling and caring 

 for such products in such a way that the period of usefulness may 

 be prolonged. This work, as a whole, has a direct connection with 

 war-emergency thrift problems, and a large amount of material has 

 been brought together. 



Correspondence with housekeepers, extension workers, teachers, 

 and students markedly increased. This feature of the work is of 

 great importance, not only for the opportunity it offers to aid house- 

 keepers in some of their special problems, but also because of the 

 useful and varied information which they furnish to the office.
