MEMORIAL OF C. W. HAYES 99 



The problems met with during the day were discussed around the 

 evening camp-fire, liayes had great facility in drawing out a young 

 geologist and finding out his point of view. Though he made tlie final 

 decision on a problem under joint investigation, Hayes was always ready 

 to listen to interpretations made by an assistant. If, however, he as- 

 signed a definite problem to an assistant, he left him to work out his own 

 salvation. 



One of the reasons for Hayes's success in his field-work was the ad- 

 miration he inspired in his assistants. All became his devoted followers, 

 yet his influence did not tend to make disciples, but rather independent 

 thinkers. He insisted that they search out all the facts and then draw 

 their own conclusions. Hayes's wonderful success as an administrator 

 of large affairs was due to the same quality. His policy developed men 

 to their highest capacity and then put them to their best use. 



Hayes closed his areal mapping in the southern Appalachians in 1896, 

 though a little supplementary work was done the next year. Unfortu- 

 nately for the science of geology, the inaccuracy of the base maps de- 

 ferred and in certain instances prevented the publication of many of the 

 folios which had been prepared at so great a cost of time and labor. On 

 April 30, 1897, he writes': 



"In addition to tlie folios, T wish to prepare for publication during the com- 

 ing year a monographic report on the entire area surveyed by myself and 

 assistants in the southern Appalachians during the past ten years." 



Some months later he says : 



"My office work has been cliiefly on the monograph." 



Unfortunately, owing to other assignments, Hayes never completed 

 this monograph, and the results of a decade of intensive study are re- 

 corded in only a fragmentary way. Many of Hayes's ideas and the prin- 

 ci])1es estal)lished by him were incorporated in the work of others, and this 

 is as he wished it. Hayes always gave freely to his associates and subordi- 

 nates, for his ideal was results and not personal glorification. This can 

 be illustrated by a personal experience. A junior geologist working as his 

 assistant had opportunity to prepare a geologic paper involving such ex- 

 tensive use of Hayes's unpublished material as to justify joint authorship. 

 The junior was, however, instructed to prepare the article, to use any 

 material he desired, and publish it over his own name. 



While the broad plan of quadrangle mapping and folio publication is 

 to be credited to Powell, Gilbert, and AYillis, yet in its execution Hayes 

 played an important part. He was the author of number 2 of the series
