THE TRAINING OF TECHNICAL CHEMISTS.* 

 The world's growth in manufacturing 

 industries has increased enormously during 

 the last century. This marked progress 

 has resulted from a greater and more 

 widely diffused knowledge of the sciences - 

 and their application. In this great ad- 

 vance the United States, aided by her won- 

 derful and vast natural resources, has 

 taken a very important part. In 1850 the 

 value of manufactured products in the 

 United States was $1,000,000,000. This 

 has increased to the astonishing figure of 

 $13,000,000,000 in 1900, while the value of 

 unmanufactured agricultural products was 

 estimated at $4,000,000,000. 



In bringing about this increase, chem- 

 istry, assisted by engineering, has played 

 a most important part. Our iron and steel 

 industries, our v/hole field of metallurgy 

 and, indeed, the majority of the great in- 

 dustries, would have remained in a crude, 

 dormant state had it not been for the im- 

 portant work of the chemist and his more 

 practical brother, the technical chemist. 

 When we realize that the value of our 

 manufactured products is three times as
