The cheapest food is that which furnishes the largest 

 amount of digestible and healthful nutrients at the least 

 cost. The cost of one pound of round steak is about twelve 

 cents; of one pound of sirloin about fifteen cents; and of 

 one pound of milk about two and one half cents. In price 

 five pounds of milk is equal to one pound of round steak, 

 and six pounds is equal to one pound of sirloin steak.
