TWO RATS BROUGHT TO THE} VERGE OF BERI-BERI AND ONE THEN CURED THROUGH 

 THE USE OF DRIED CELERY LEAVES 



The smaller rat was fed on a diet low in the "water soluble B," and was near having beri- 

 beri. The large one was brought to the same condition and was then given 10 per cent of 

 dried celery leaves. He gained weight with phenomenal rapidity and quickly became a fine- 

 looking specimen, according to Dr. McCollum. 



table galaxy, with its bewildering variety 

 of flavors and colors. 



the American's habitudes are 

 changing 



With every one saying it can't be done, 

 the American is changing his habitudes, 

 his tastes in foods. 



And now the supreme moment has 

 come to put this characteristic of the 

 American civilization to account. 



When once we learn to like dried vege- 

 tables — and if they are properly dried 

 and properly cooked they taste so nearly 



like the fresh ones as to be almost indis- 

 tinguishable — there will be unlocked vast 

 storehouses of food in the sweet-potato 

 areas of the South and equally vast sup- 

 plies of Irish potatoes in the North, now 

 threatened with complete or partial loss. 

 It is extremely difficult to predict the 

 course of events in any change of human 

 habit. Could Sir John Hawkins have 

 dreamed, when he introduced a Peruvian 

 tuber as a curiosity into Ireland, that his 

 great-great-great grandchild (if he has 

 one) would see 155,000,000 bushels of 

 potatoes produced in that island alone?
