THE WORLD'S ADVANCE for JULY 



A Great Technical Library 



In Simple Language 



Out of a world-wide experience in teaching the engineering trades and 

 professions by correspondence the International Correspondence Schools have 

 perfected the greatest system of textbooks in existence. More than $2,000,000 

 has been expended in their preparation and $100,000 is spent annually to 

 keep them up to date. 



Prompted by many requests for these textbooks without the correspondence 

 instruction the publishers have issued a special edition from which the very 

 elementary subjects and examination questions have been omitted. These 

 volumes are now being offered for sale to the general public in lots of five or 

 more on easy monthly payments.

 simplest terms so that men with only an ordinary 

 education can easily understand them. And each
