POPULAR SCIENCE MONTHLY 



and 



THE WORLD'S ADVANCE 



Good News to our Readers: 



The WORLD'S ADVANCE has purchased 

 the Popular Science Monthly, a publica- 

 tion of long established reputation, and be- 

 ginning with the October number these 

 two publications will be consolidated into 

 a bigger and better magazine. 



In science, in invention, in mechanics, 

 in electricity, the greater magazine will 

 continue to give its readers Truth, which 

 is ever stranger than fiction, and facts 

 which are more absorbingly interesting 

 than fiction. 



Never before in the history of our coun- 

 try have inventions, mechanics, electricity 

 and all the subjects that come under the 

 broad head of Science been of such vital 

 interest, of such usefulness, of such im- 

 portance to our country itself as right 

 now. 



More pictures, better pictures, more 

 news of THE WORLD'S ADVANCE, more 

 pages of reading matter than ever before 

 will mark the future issues of this maga- 

 zine.
