18 ANNUAL REPORT OF THE 



REPORT OF THE STURGIS HOOPER PROFESSOR OF 



GEOLOGY. 



By William E. Davis. 



My teaching has been limited to the advanced course of re- 

 search in Physiography (Geol. 20a), which was attended by seven 

 students. The problems discussed were: — the physiographic 

 treatment of faults, the physiography of Washington and of 

 Wales, experiments in different methods of physiographic descrip- 

 tion, and the physiography of three districts in western Canada; 

 the latter subjects were treated by three junior members of the 

 Geological survey of Canada, who attended the course during the 

 second half-year, and who presented their reports on field work 

 of the previous summer as a basis for discussion in the class. 



My personal work for the first half-year was chiefly devoted to 

 the completion of the manuscript and drawings for my Berlin lec- 

 tures of 1908-1909, now in process of publication under the title: — 

 "Die Erklarende Beschreibung der Landformen." A small share 

 of time was given to revision of a German translation of my 

 "Physical Geography" by Dr. G. Braun, of the University of 

 Berlin. During the latter part of the winter, about two months 

 were given to the writing and illustration of an account of a visit 

 to the Rocky mountains of Colorado in the summer of 1910. 

 This article gives special attention to method of treatment as well 

 as to the subject treated. During the spring a beginning was 

 made on a long-postponed task; the writing of a book on the 

 "Forms of the Lands" for students of university grade. Further 

 progress on this undertaking has been interrupted by the prepara- 

 tory work incident to my appointment as visiting professor to the 

 University of Paris for next winter. 



An active correspondence has been carried on during the late 

 winter and spring in the preparation of two geographical excur- 

 sions; the first, a "Geographical pilgrimage to Rome," has been 

 planned in connection with Dr. F. Nussbaum of Bern. This will 

 begin in Ireland and will reach Italy in early October, in time to 

 take part in the International Geographical Congress at Rome. 

 The second excursion, named the "Transcontinental Excursion of
