we heard that he was a sliark in iiiatheinatics, and we began to hear tliat 

 he was a shark in pliysics. AVe did not know any more about physies 

 than we did al)()ut Hebrew, but we were ghid to have a shark among 

 us. After a while Me were ghid tliat he became a professor in our 

 university, and we were prouder still, tbougli somewhat sad, wlien lie 

 was called to Yale. Then after he left us we began to hear that he was 

 one of the greatest physicists in America. We were glad to hear also 

 afterwhile that he had concluded to come back to his old university, 

 his old city, and his old fisliing grounds. 



Then the war came on, and we began to hear that our friend was 

 experimenting out on T^ake ]Mendota to further the demands of our 

 country for means to check the advance of the Kaiser and Hinden- 

 burg and their submarines in their attempts to sink the navies of the 

 Allies. We thought it was a pretty big job he was undertaking, and 

 a rather small field for his operations, but we had faith in him, and 

 presently we heard of his experiments along the Atlantic Coast; and 

 then we heard that he had actually invented a device that would detect 

 the coming of the submarines. Then we heard that he had been called 

 over to England to consult with the scientists and the naval experts 

 of the Allies — and finally he came back. He is here tonight. He has 

 been called upon to step into the breach to take the place of a celebrated 

 engineer who had intended to come. 



I have the pleasure of introducing Professor ^lax ]\Iason who will 

 speak to you.
