turns. By the proper application of their strength men 
are able to lay several times as many bricks in a day 
or to transport several times as much iron without 
fatigue. It is simply a question of doing it the easiest 
way and cutting out waste motions. To be a truly effi- 
cient nation this system should be greatly extended. 
The effort to conserve human life, health and energy 
linked with the conservation movement as a whole is 
occupying much attention at present. In our mad 
rush to get things accomplished there has been an 
appalling waste of life and health in the past. Men like 
Holmes, Wiley and Lindsay have been preaching that 
human life and health, manhood aud womanhood, boy- 
hood and girlhood are the most precious resources that 
this nation possesses. It is gratifying to note that their 
warnings have been heard and that their advice hag 
been heeded to a large degree. 
With the passing of the period of free land we 
entered the middle age of our national life. It is high 
time that we discard the reckless and extravagant ways 
of youth and commence to use our wealth soberly 
and thriftily. President Roosevelt stated at the White 
House conference that the conservation of our natural 
resources was the most important question hefore this 
nation and this remark is as true today as it was eight 
years ago. Every citizen who is truly a patriot should 
do his share toward making the America of tomorrow 
a more comfortable, more prosperous and a better place 
in which to live for the benefit of generations yet 
unborn. |
