chemical bench, behind which was an ordinary canvas army cot. 

 There was a hood in one corner and a sink next to the door. There 

 was no room for anything else. There was notliing new in the room; 

 everything in it looked as though it had been used continuously for 

 many years. I later found that there was one exception to this— a 

 new, large Webster's Dictionary which had escaped my attention, as 

 it was kept rolled up in a green cloth and tied with a string. In spite 

 of this, however, it was very often used. 



After a word or two of greeting I started to tell Dr. Abel about my 

 forced change of plans, but he interrupted me almost at once, saying, 

 "That is too bad, but let us put that off until we have an evening at 

 our house together. If you have no problem on hand at the present 

 minute, let us start on something which has become of the greatest 

 importance on account of the war." He then suggested that we at- 

 tempt to treat pig's blood so that it could be used in man to replace 

 human blood without causing hemolysis and reactions of one sort and 

 another. This sounded a bit wild to me, but I did not dare to say so. 

 He gave me a white coat of his own, hung mine on a hook on his door, 

 sent the laboratory boy to the nearby slaughter house for pig's blood, 

 and within fifteen minutes after I came into his room I was actually 

 at work and on a problem which kept me busy for over ten years al- 

 though it was not two days before I gave up the pig's blood idea 

 forever. How many men would have been able to diagnose instantly 

 the state of confusion brought about by such a change in one's life 

 and without a word have started one off on a course which effected a 

 cure almost instantaneously? 



At just the time I went there, Baltimore was starting to grow up 

 and to lose much of its old charm, which, however, has been replaced 

 by much of beauty. The automobile was just coming in, and a few 

 people were moving out of town, but many of the best families still 

 lived in the city and sat on their doorsteps after dinner on warm 

 evenings; and on the way home it was the custom for one to drop 

 into the Maryland, Baltimore, or University Clubs, where one was 

 sure to find friends. The University had not moved out to Home- 

 wood, and I lived and dined with a very pleasant group at the Johns 

 Hopkins Club on the corner of Monument and Howard Streets. 

 Each morning we would walk across town to the School. As we began 

 our pilgrimage we would pass houses with beautiful doorways, the 

 brass knockers and nameplates of which were being polished by those 

 fine old colored men of the old school, and before we had passed 

 the Washington monument, we were sure to have been greeted with a
