REPORT OF THE STURGIS-HOOPER PROFESSOR OF 



GEOLOGY. 



By Willtam M. Davis. 



The instruction given by Professor Davis was, as during recent 

 years, a whole course in advanced Physiography and a half-course 

 of intermediate grade. The latter was upon the United States, 

 and in it the laboratory work on charts, maps, and folios was, 

 with the assistance of Mr. Read, developed to a much more satis- 

 factory stage than heretofore. In the advanced course the prin- 

 cipal problems discussed were : Piedmont fluviatile plains ; the 

 meanders of the Mississippi ; the geographic features of extinct 

 glacial lakes ; the movement of sands on beaches ; the principles 

 of regional physiography, and outlines for practical laboratory 

 exercises. During the autumn and early winter a good share of 

 time was given to the preparation of two reports on the work of 

 the previous summer in Utah, Arizona, Nevada, and Oregon, one 

 of which has been published in the Museum "Bulletin," and the 

 other of which is in press. The former is chiefly concerned with 

 the faults by which the plateaus of southern Utah and northern 

 Arizona are divided. The latter is a discussion of the Basin 

 range problem, to which renewed attention has been recently 

 turned. At the same time supervision was given to the special 

 report on the Hurricane Fault in the Toquerville district of 

 southern Utah by Messrs. Huntington and Goldthwait, who ac- 

 companied Professor Davis on his western excursion. A short 

 excursion was made in November to Mt. Mitchell and the Blue 

 Ridge of North Carolina, with special consideration of the Blue 

 Ridge as a retreating escarpment ; the results have been published 

 by the Geographical Society of Philadelphia. A certain share of 

 time has been given to the organization of the Harvard Travellers 

 Club, with the object of bringing together Harvard students and 

 graduates, and others interested in the promotion of intelligent 

 travel and exploration. The plan has met with an encouraging
