MEMORIAL 03? C. W. HAYES 93 



While working on this research for his doctorate^ he was also working 

 up a collection of rocks from Fernando de Koronha under Doctor 

 Williams. 



Though Hayes was deeply immersed in scientific studies, he still found 

 time for other academic subjects. His correspondence shows that he 

 attended lectures on German and English literature and took a course 

 on pedagogics under Prof. G-. Stanley Hall. Of him he writes : 



"He is a most delightful lecturer, and it is quite a relief to spend an honi* 

 with the humanities after being 'exposed to science' all the week." 



A fellow-student at Johns Hopkins writes that Hayes gave him the 

 impression from the start of being a student who was not content to take 

 a statement for granted; but he was always adding something, trying 

 out some reaction, testing some new possibility. He also speaks of the 

 inspiration of the teaching of Doctor Williams, who 



"kept us constantly on the qui vlve for announcements of new discoveries, and 

 in it all Haj^es was one of the foremost students. He [Hayes] was gifted with 

 a keen sense of humor^ — not a bad quality in a crowd of strenuous young stu- 

 dents." 



Hayes, with two or three others, made some 5 or 1 grains of sulphinide 

 (saccharine), Doctor Eemsen's remarkable discovery. This was the 

 largest quantity of saccharine which had been made at that time. Doctor 

 Eemsen was much pleased and "gave us a magnificent offhand talk on 

 sulphinide." 



The official record shows that Hayes received his doctorate from Johns 

 Hopkins in 1887, with chemistry as the major and mineralogy and geology 

 as minor subjects. He devoted much of his time in the laboi-atory to 

 organic chemistry, the title of his doctorate thesis being "Sulphofluo- 

 rescein and some of its derivatives." 



Few geologists have had better preparation in the basal sciences than 

 had Hayes when he left the university. He took advanced standing in 

 chemistry, was trained in the physical laboratory, and completed all the 

 courses in geology given by Doctor Williams. It was Doctor Williams^s 

 influence that led him to take geology as a minor, without apparently a 

 thought at that time of making it his life's work. He found no oppor- 

 tunity of studying organic geology, and his lack of training in paleon- 

 tology, always a source of regret to him, was a handicap in his strati- 

 graphic studies. Strangely enough, he received but little training in 

 stratigraphy, tectonics, and physiography, thougli these were the branches 

 of geology in which he was destined to attain his highest standing as a
