92 Report of the President 



adequate daily dietaries are exhibited for an individual, based 

 on a moderate and on a restricted income, with specimens and 

 models illustrating a complete weekly food supply for a family 

 of five persons, so adjusted as to meet all essential physiological 

 needs at a minimum cost. Special cases are devoted to the 

 methods of conserving wheat, meats, fats and sugar, required 

 or recommended by the United States Food Administration. 



The Food Exhibit was shown for a period of six weeks 

 in May and June, 191 8, in the gallery of the Grand Central 

 Terminal, and for a week in June as part of the Food Show in 

 the Grand Central Palace. It was brought back to the Museum 

 in the summer and is now installed, through the courtesy of the 

 Department of Woods and Forestry, in the center aisle of the 

 Forestry Hall on the ground floor of the Museum. 



It is gratifying to note that this, — undoubtedly the most com- 

 plete exhibit of food hygiene prepared in this country, — has 

 served as a model for exhibits in many parts of the United 

 States and has therefore exerted an educational influence far 

 beyond the circle of those who have actually visited the 

 Museum. 



It is planned to develop the Food Exhibit to a considerably 

 greater extent during the coming year and to supplement its 



basic hygienic and nutritional data with material 

 Plans for illustrating the broader problems of the world's 



food supply from the standpoint of production 

 and distribution. It is hoped too that it may be possible to pre- 

 pare printed material in the form of one or more guide leaflets 

 which will present in simple form the chief lessons of food 

 hygiene and food conservation, since we have received a con- 

 stant and urgent demand for literature of this kind. 



Outside of the Food Exhibit the principal addition to our 

 exhibition material has been the installation of a 

 The Yellow model of the yellow fever mosquito, Aedes 

 Mosquito calopus. This beautiful model, which was pre- 



pared by Mr. B. E. Dahlgren, is 50 times natural 

 size and completes the Museum's series of giant models of the 

 important insect-carriers of disease: the malaria mosquito (in
