A Decennial Record 159 



lytic methods of refining metals and making steel will continue to en- 

 gage attention for some time to come. 



In welding we have made quite a record. Without this research 

 we probahly could not have repaired the German ships which were in 

 New York harbor. This has always been a very interesting subject 

 to me, for we accomplished in a few wrecks w^hat the Germans thought 

 would take years to do. All ships were damaged almost exactly alike, 

 the variations being but slight. Everybody carried out his orders, 

 there being no evidence of individuality in the methods used ; and when 

 the results were available from one ship, a method had been worked 

 out for all and it was only necessary to increase the units of the repair 

 equipment. Out of that work the American Welding Institute has 

 grown up and is now engaged upon a study of the various methods of 

 gas and electric welding. 



Perhaps there is no brighter page in industrial research in xVmer- 

 ica than the development of the art of communication. In wireless 

 simply marvelous progress has been made and is due wholly to re- 

 search. Men who learned their radio during the war and have lost 

 touch since, find such rapidly changing conditions that they must al- 

 most begin over again. Such progress is being made in the use of new 

 apparatus and the steps are being taken with such rapidity that in 

 order to keep up with wireless the men must keep in touch with each 

 development as it unfolds piece by piece. The wireless telephone 

 strikes me as being one of the most remarkable accomplishments. That 

 we can send waves traveling as from tlie center of a sphere witli such 

 intensity that part of them will reach a distance from Washington to 

 Paris or Hawaii with sufficient force to be heard is a modern miracle. 



You heard from Professor Mason last night about research on 

 one ty])e of communication that was carried on in many of our labora- 

 tories during the war. 



The rubber field is another glowing exam])le of what American 

 research has done; and still anotlier can be drawn from fields of elec- 

 tricity, chemistry and engineering in the ]Mazda lamp. The use of this 

 lamp is said to mean a saving of $-100,000,000 annually as compared 

 witli our old carbon electric light bul])s. Our scientific men fought 

 with German scientists for the ])rize: both knew the advantages of 

 tungsten filament and tliat ductile tungsten was the next step. Our 

 men were first to solve the problem, and also to learn that the use of
