228 PHYSIOLOGY. 



Forms of Exercise. In selecting the kind of exercise 

 the old lines fit well : 



" In whate'er you sweat, indulge your taste ; 

 The toil you hate fatigues you soon, 

 And scarce improves your limbs.' 1 



Of course this does not mean that a boy should refuse 

 to saw wood because he dislikes it, and spend all his time 

 playing ball. But for older persons, especially those of 

 sedentary occupation, exercise that exhilarates is far more 

 beneficial than that which is not enjoyed. One may take 

 a walk and carry all his cares and anxieties with him, but 

 he is not likely to think of such matters when playing 

 tennis with a good opponent. Whether it be horseback 

 riding, cycling, boxing, boating, skating, or other form of 

 exercise, choose, whenever a choice is possible, that which 

 you thoroughly enjoy. Exercise should be taken out 

 doors whenever possible. The gymnasium is a substitute 

 in bad weather. 



Games of School Children. Most of the games of 

 school children are excellent kinds of exercise. Cases 

 have been reported of injury from excessive skipping the 

 rope. But in moderate degree it is a good exercise. Tag, 

 snowballing, racing, the various games of ball, jumping, 

 hopping, and other games may be played on the school 

 grounds. 



Tennis. Tennis is a fine game, and suitable for girls 

 as well as boys. It has the great advantage over baseball 

 that it does not require a large ground (which often means 

 going some distance from the school grounds or from 

 home). Two can make up a game, and a little time can 

 be better utilized than with the games requiring more 

 players. The exercise, too, is more evenly distributed.
