quenching the armor to specific hardness. We also did some work in heat- 

 treating nickel-chrome steel and made it possible to treat heavy plates for 

 uniform structure, regardless of plate gauge. 



There is a building story in which you might be interested. We were short of 

 space in the A&P Lab, and I asked Captain McLaren if we could get any 

 additional square footage. He called me over and said, "You need more space, 

 don't you, Commander?" I said, "Yes, sir." "Well," he said, "you've got a builder 

 there, don't you?" I said, "Yes, sir, I have. He used to be a contractor. He 

 worked as a carpenter for me." He said, "You have an electrician, too, don't 

 you?" I said, "Yes, there's one attached to my place." He said, "I haven't 

 disapproved any orders for materials you have sent over, have I?" I said, "No, 

 sir." He said, "Don't let me catch you building anything."
