Cunliullmy it. at you and 



I were in the business of manufacturing chemicals 

 dyestuffs, for example. In the course of secur- 

 ing the colors we had a liquid left over. This 

 liquid had always been thrown away, because it 

 was not of any further value in getting dyestuffs. 

 One day, one of our workers dropped a monkey 

 wrench into a pan of this liquid with the result that 

 he was blown out of the window. This would 

 indicate that we might be able to sell that liquid, 

 properly packed, for explosive. Let us further 

 suppose that we decided to sell the liquid and, 

 from some experiments we made, we decided that 

 certain si/cs of cartridges should be made in order 

 to give the proper power for certain kinds of 

 work. We would find, after a while, that some of 

 the cartridges were too powerful and some not 

 powerful enough. The liquid would not be uni- 



:n, because it was only what was left 

 from our regular business of making dyes and 

 :id not know how to handle it properly. 



In order to be able to control the manufacture 

 of this liquid so that it would always contain a 

 given amount of explosive power for a certain 

 amount of liquid, we would be obliged to put it 

 in the laboratory and find out what it was made 

 of, how it was produced during the process of 

 making dyestuffs, and why it possessed the ex- 

 plosive power. Then we could rearrange our 

 processes so that we could always get the same
