Food Conservation 97 



illustrates the amount of each food which will supply ioo cal- 

 ories of energy to the body. Tables set for breakfast, lunch 

 and dinner show satisfactory dietaries for an individual, based 

 on either a moderate or a restricted income. 



Numerous exhibits are included dealing with unutilized food 

 stuffs of various sorts, particularly seaweeds, marine mollusks 

 and food fishes (shark, skate, etc.). 



Food production problems are illustrated by photographs, 

 models and specimens which tell the story of wheat and of corn 

 from the grain fields through the flour mill, and from the 

 bakery to the home. 



The food conservation problems of the war are brought 

 home by statistical diagrams and a series of striking colored 

 cartoons prepared by Mr. A. Operti.

 this important task we have been fortunate in securing the 

 cooperation of the Department of Home Economics of Co-

 of assistants in that department. 



The exhibits in the Hall of Public Health dealing with 



insect-borne diseases have been supplemented

and models illustrating the campaign against typhus fever in 



Serbia, and amplifying other material on insect-borne diseases. 



A fine series of transparencies has been purchased, illustrat-

 the yellow fever mosquito, Aedes calopus, prepared by Dr. 

 B. E. Dahlgren, is almost completed. 



The exhibits at present installed in the Hall of Public Health 

 have been made more readily available for the use of teachers 

 and students by the publication of a special "Syllabus Guide to 

 Public Health Exhibits" by Mr. L. V. Coleman, giving in brief 

 outline the principal facts which the student ought to know 

 about Water Supply, Municipal Waste Disposal, and Insect-
