result within very narrow limits of error. But 

 we would not have been able to make it uniform 

 and get the same results if we had not passed the 

 stuff into the laboratory ami allowed the chemists 

 there to experiment with it until they knew the 

 answers to the questions that have been stated 

 in this paragraph. 



It is in just this way that experience is turned 

 into science. Every man who seeks to find out the 

 reasons for action, and the things which control 

 the action, is a scientist, and science is the written 

 record of the way in which results can be con- 

 trolled by utilizing known causes. 



Organizing the Information. It is this organ- 

 ization of information, by research and study and 

 practical experiment, which enables us to develop 

 methods that are calculated to give practical con- 

 trol of results. How much this has developed 

 our capacity for production in the last few years 

 can be determined very easily by thinking back 

 to the way things were done twenty or twenty-five 

 years ago and comparing the methods of manu- 

 facture at that time with the methods of manufac-

When we know that a thing happens we can 

 take advantage of that happening in order to
