MAINE AGRICULTURAL EXPERIMENT STATION. 



THE INFLUENCE OF THE SUPPLY OF ANIMAL FOODS UPON THE 

 SIZE AND COST OF THE DIETARY, WITH ESPECIAL REFERENCE 

 TO MILK. 



As has been stated, the attempt was made in four dietary stud- 

 ies to deliberately control to some extent the supply of animal 

 foods and the source of protein. The attempt was also made to 

 determine the relative value of milk in the dietaries. 



The following table briefly summarizes the amounts and kinds 

 of food materials purchased in the four dietaries:
