Of all the magazine readers in America, probably 

 no group would show so high a percentage of 

 efficiency as the Popular Science Monthly family 

 from the standpoint of our Country's need in the 

 present crisis. 



In the first place, a verv^ large proportion of our 

 many thousands of readers are young men — vigor- 

 ous, intelligent, alert. 



In the next plare many — very many of our readers 

 follow vocations which, from the economic stand- 

 point, are vitally important to the Country's pro- 

 gram of preparedness and conservation. 



In the third place, where could you find so im- 

 pressive a number of men — and women too — ^with 

 the inventive type of mind? Who can tell what 

 will be evolved from the experiments and discov- 

 eries of Popular Science Monthly readers and how 

 far-reaching the benefits thereof to our Country? 



We must, one and all, in whatever direction the 

 path of duty lies, give the best that is in us, 

 placing patriotism above selfish gain; self denial 

 above personal indulgence. 



Our Country is a land of liberty and opportunity. 

 Let us search our hearts and our brains for those 

 qualities whereby each one of us can best do his 

 share towards preserving and upholding these price- 

 less attributes.
