MEMORIAL OF A. H. PURDUE 59 



still remember that when we were working together in the mountains of 

 Arkansas, it was my method to fall into the ways of the people with whom 

 we were living, especially in adopting the vernacular of the region — a 

 habit to which Purdue always objected and for which he often chided me. 

 He would insist that, as educated men, we had no right not to give the 

 mountain people a glimpse of correct English. This same regard for the 

 Queen's English is seen in the painstaking care with which he edited all 

 of the manuscripts published by him as State Geologist. 



As a field geologist, Purdue was tireless, painstaking, and thorough, 

 and the same energy and careful attention cluxracterized all of the prepa- 

 ration of his reports. Tliis desire for high quality and accuracy doubtless 

 reduced somewhat tlie number and lengtli of papers prepared by him, 

 but his work made up in (piality what it lacked in volume. 



While he was at the TTni versify of Arkansas he spent the summer 

 months in the field in that State — most of the time in camp with a party 

 of from one to three of his students — and wrote his reports at odd mo- 

 ments during the school year. Although his field-work was varied, it 

 consisted mainly of detailed areal mapping for the United States Geo- 

 logical Survey in a number of quadrangles in the northwestern and west- 

 central parts of the State. Whenever funds were appropriated by the 

 Arkansas legislature for tlie State Survey he made it count as much as 

 possible by cooperating with the United States Geological Survey. Most 

 of his geologic work in Tennessee was administrative, but he found time 

 to make numerous short field tri])s into difi^erent parts of the State. 

 Much of the work carried on under his administration as State Geologist 

 in that State was done in cooperation with the United States Geological 

 Survey and the United States Soil Survey. 



Among his more important papers are the Winslow and Eureka 

 Springs-Harrison folios and the De Queen-Caddo Gap and Hot Springs 

 folios, awaiting publication ; the slate deposits of Arkansas, besides a 

 large number of shorter publications issued by the United States Geolog- 

 ical Survey, State Surveys of Arkansas and Tennessee, and many others 

 published in magazines or elsewhere. Considering the large amount of 

 administrative work in the University of Arkansas that fell to his lot, 

 this is a rather remarkable showing of scientific results for a teaching 

 professor occupying practically the whole bench of geology. 



Mr. Purdue was a member of the American Institute of Mining Engi- 

 neers, the Indiana Academy of Sciences, the National Geographic Society, 

 and the Seismological Society of America. He was a Fellow of the 

 American Association for the Advancement of Science, the Geological 

 Society of America, and the Geological Society of London. He often
