1 QO exploitation, but by holding and developing them as a trust for 

 civilization. 



Here, his ideal of the doctor was speaking, as it had been 

 bred into him on Halsted street in Chicago and nurtured by 

 his trampings about the world. This man was to go forward 

 but not as conquistador, salesman or tax collector, but as one 

 charged to make better this human existence. 



The modern moment had separated economics and sociology 

 from the spiritual body of man; so had the biological sciences 

 broken with folklore, with fairy tales, with what some are 

 pleased to call "religion." What Wherry thought in such mat- 

 ters is best told in his own words, wherefore this lengthy 

 excerpt from his scientific exposition of plague [44] . 



Comparatively recent discoveries have placed in the hands of 

 man a sure remedy against the plague. For now we know the 

 elements which, when brought into conjunction, start that 

 prairie fire which thrice, in recent times, has swept the earth 

 with its destroying blast. Certain rodents, their fleas, and man 

 are the combustibles; B pestis the spark. 



Medical prophylaxis looks into the future as far as possible, 

 and builds a barrier which, though like the wall of China 

 takes a hundred years, stands forever. All efforts which bring 

 about temporary prophylaxis alone are wasted, along with time 

 and money. Why is it that even so-called civilized races resist 

 our efforts to bring about immunity to disease? The answer 

 would be totally discouraging were not ultimate victory so 

 desirable. . . . Thus the plague problem is narrowed down 

 to the rat problem. . . . 



Rats did not embark with Noah. For is it not revealed in the 

 Quassul Ambia of the Mohammedans how that patriarch, hav- 

 ing forgotten in his hurry to install sanitary arrangements in 

 the Ark, appealed for help from on high? The pig was created 

 to clean up the accumulated offal ; but the ever-restless Shaitan 

 drew forth from the pig, rats which multiplied enormously, 

 and their gnawings endangered the whole animal kingdom. 

 The angel Gabriel, descending upon request, instructed Noah, 

 and he, passing his hand over the nostrils of the tiger, drew 

 forth cats, which soon held the rats in check. One should be 

 glad to know this in order to place blame and shame where
