resources. Even such problems, however, he could not handle solely 

 from an economic point of view. His studies of Snake River Valley 

 and other similar problems made a decided contribution to the general 

 scientific theory of igneous action. 



In Michigan University he made no such impression as in the work 

 of the Geological Survey. President Angell himself told me that he did 

 not consider that it was necessary for every State University to build 

 up a great geological department; and as Wisconsin had had two great 

 geologists as presidents he did not feel called upon to rival her. Nor 

 was Russell, with his artistic temperament, the type of man who 

 rejoices in running a large department. 



He was, however, keenly interested in the Michigan Academy of 

 Science, was among its early presidents, and served it in many ways. 

 As his connection with the U. S. Geological Survey became less he 

 found time to take up some of the local problems of Michigan. He 

 was never a specialist in Paleontology and therefore did not pretend 

 to continue the researches of Alexander Winchell, his predecessor; 

 but he reverted naturally to those studies of the lakes and of surface 

 geology which had interested him from the very first paper he printed. 

 He really inspired the stud.y of the almost unique delta of the St. Clair 

 River made by Leon J. Cole, one of his students. He also prepared 

 a study of the surfaice geology of a good part of the upper peninsula 

 and its molding under the ice, and threw light on the origin of drumlins 

 and hills of the same canoe-shaped type due to the remodelling of 

 preexisting till sheets, and also on the curious Indian ridges known as 

 ■eskers. Having been used to topographic maps in his western work 

 he naturally felt the lack of them on coming to Michigan and began to 

 agitate for the co-operation of the State with the U. S. Geological 

 Survey in their preparation. If it had not been for him I do not 

 think this co-operation would have begun as soon as it did. 



His scientific works, a complete bibliography of which is given by 

 Willis, may be grouped as follows: — 1st, a series of papers on lakes, 

 their origin and phenomena, in which he treats the modern Great 

 Lakes and those of New Zealand and those shrunken remnants of 

 lakes like the Great Lakes, out West, especially Lake Lahontan, the 

 monograph on which he prepared ; 2nd, a series of papers culminating 

 in a correlation essay on Triassic and allied beds of the Atlantic 

 Coast, which he called the "Newark Formation"; 3rd, a series of 

 descriptions, in which he appears both as artist and savant, of those 

 great contrasted phenomena of nature, the volcanic eruption and 

 the wondrous obelisk of Mt. Pelee on the one hand, and on the other
