arouse and maintain interest in our classes. “Interest,” said Joseph 
Cook, “is the mother of attention, and attention the mother of mem¬ 
ory; if you would secure memory you must first catch the mother and 
the grandmother.” If we would be certain of intelligent interest from 
the beginning we must make sure that the bearing of our particular 
study on college training in general is understood by our students. 
Certainly there is a reason why we propose to ask their time and 
attention. If there is none we’d better do something else. But the 
real relation of that particular study to the student’s equipment may 
be quite obscure and its bearing once revealed may be an agreeable 
surprise. 
Throughout all of our contacts in teaching we shall greatly help 
ourselves and our work if we thoughtfully cultivate a sympathetic 
understanding of the student’s point of view. It is not the same as 
ours. The scale by which he measures the importance of life’s events 
is different from ours. In any life such a scale is constantly changing. 
Our own has materially altered and will keep on changing so long as we 
live. We are apt to forget that and thereby to misjudge a student’s 
exuberant interest in fraternities, sports and kindred affairs. Those 
things are his own. They are absorbingly interesting. If we permit 
our classes to be dull can we wholly blame him for his choice? 
In any of the contacts into which the winding path of the day’s 
work may lead us, we, ourselves, form half of the bargain. Adjust¬ 
ment then must always be as much concerned with the person that 
travels the path as with the path itself and its other travelers. 
In this purely subjective side there can be no doubt as to what factor 
ranks first. A good many years ago a man named Paul, in a letter to the 
people of Corinth, spoke reverently but sternly of the human body as a 
temple. For thousands of years before that and through every year 
since, the admonition has been constantly repeated. It must be con¬ 
fessed that we need it. 
The fact that we as scientists are engaged in work of a mental char¬ 
acter may make the way easy to imperfect health, but it in no wise 
makes that physical state allowable. On the contrary, because of its 
mental product, our machinery for the day’s work is the more easily 
rendered inefficient. No mental process takes place without a corre¬ 
sponding physiological output. We drive our team of body and mind 
with a single pair of reins. As we direct the one, so goes the other. 
In speaking of health we mean today more than freedom from 
obvious bodily impairment. There is a state of health much higher 
than that, a physical trim, a complete well-being in which one’s poise 
is perfect and alert, one’s energy instantly ready, one’s reserve full
