 and badly prepared building material.

 for the juices of the stomach. They also claim 

 that with such mastication too much food is not so 

 likely to be eaten, because much more time is occupied 

 in chewing. Persons who have persevered in this 

 habit are most enthusiastic over the results, because 

 of recovered health and increased ability to endure 

 physical and mental exertion. 



Boys will be interested in an experiment tried 

 at Yale University by some young men who were 

 active in athletics and had the habit of eating heartily, 

 with no especial care about chewing their food. They 

 were induced to make a special point of thorough 

 mastication for a certain period. As a natural result 

 of the increased length of time occupied in chewing, 

 the quantity of food they ate was largely decreased. 

 For this reason you might expect their activity and 

 endurance in games would have correspondingly 

 lessened. On the contrary, they were able to play 

 faster, longer, and more accurately. This is certainly 

 an excellent object lesson for all who want to do their 

 best at games and sports requiring strength and skill. 



We learn early in life to use with care any 

 article or instrument that by cutting or burning may 

 hurt or mar our bodies. How important it is also to
