98 PROCEEDINGS OF THE ALBANY MEETING 



in tlie front rank of American pliysiugraphers, this in spite of the fact 

 that it was more or less of a by-product; for both Hayes and Campbell 

 were then chiefly engaged in stratigraphy and structural researches. 

 Though more than a quarter of a century has passed since the appearance 

 of this monograph, it still remains the only comprehensive treatment of 

 the subject. Hayes continued his physiographic studies in the southern 

 Appalachians, and the results appeared in folio and other publications; 

 but his most notable later contributions to this science dealt with Central 

 America. 



Geologic Folios 



During the first decade of his connection with the Federal Survey 

 Hayeses principal task was areal mapping and the preparation of geologic 

 folios, though during this time he also entered other fields of geology. 

 His executive ability was not severely tested at this time, though it was 

 manifested by his conduct of field parties. Each member of his party 

 had definite duties to perform, and the daily routine was thoroughly 

 systematized, though there were no very obvious regulations or machinery 

 to bring this about. For example, the time for the evening meal was set 

 at 6 0^ clock, and a wait of fifteen minutes was made for each man who 

 was late. A scientific assistant was not permitted to take part in camp 

 work unless an emergency arose, when the labor was shared by all. He 

 held that a geologist should not be burdened with unnecessary manual 

 labor, yet when occasion demanded it there were no camp duties which 

 he did not cheerfully perform himself. His camps were comfortable, 

 almost luxurious, and special effort was made to provide as great a variety 

 of well cooked food "as the camp afforded. His favorite caution to the 

 cook was, "The best is none too good.^^ There was always one day^s rest 

 each week. If rain prevented field-work during the week, the party 

 worked Sundays. As a consequence of this management the party was 

 always keyed up to do a maximum amount of work. 



As already stated, the inadequacy of the topographic maps of that day 

 made it necessary for the geologist to prepare his own base. All geologic 

 observations were located by traverses, made on foot, horseback, or buck- 

 l)oard equipped with odometer. Tlie traverses were j^h^tted dii-ectly in a 

 notebook with the use of celluloid jjrotractor. Cojilours were sketched, 

 elevations being approximately determined by baj'ometer. Ifaves was a 

 master of rai)id traverse surveys, which he coukl make under any and all 

 conditions. I have seen him on his horse in a heavy i-ain platting his 

 notes and protecting the leaves of the book by holding it directly over 

 his head.
