14 ANNUAL REPORT OF THE 



of Chinese Turkestan, and thence westward to Ferghana in Rus- 

 sian Turkestan. His observations prove a succession of several 

 glacial epochs, and corroborate my conclusion as to the re-eleva- 

 tion of the mountain ranges. 



The usual courses of instruction have been given during the 

 academic year. In the advanced course (Geology 20), special 

 studies have been made by several graduate students on shore 

 forms of Lake Michigan, glacial cirques in the Rocky Mountains, 

 river meanders and cut-offs, river systems of Iowa, piedmont flu- 

 viatile plains, glacial sand plains in the Sudbury Valley, Mass., the 

 gorge of the Tennessee River at Chattanooga, and other problems. 

 These studies have for the most part been based on field-work and 

 extended by reading and discussion. The study of the gorge of 

 the Tennessee River by Mr. D. W. Johnson, instructor at the 

 Massachusetts Institute of Technology, included two weeks field- 

 work in the Chattanooga district, with the result of demonstrating 

 that the river has followed its present westward course below 

 Chattanooga since early Tertiary time at least, and that there is 

 no evidence that it ever flowed directly southwest, via the Coosa- 

 Alabama, to the Gulf of Mexico. In the course on the Physiog- 

 raphy of Europe (Geology 7), increased use has been made of 

 graphic exercises, chiefly in the drawing of typical diagrams from 

 large scale maps ; this innovation has proved instructive and it 

 will probably be systematically extended hereafter. 



After corresponding with the Geological Departments of a num- 

 ber of other Universities, a plan was adopted for the preparation 

 of a single circular in which all the field courses in Geology for 

 the summer of 1904 should be described. The circular was issued 

 in April as a " Joint Announcement," by Chicago, Columbia, Har- 

 vard, Johns Hopkins, and Yale, and thus placed before students in 

 all parts of the country the various opportunities offered for sum- 

 mer field-work. It is hoped that this plan may be farther developed 

 for the summer of 1905. Several friends of our Department of Geol- 

 ogy and Geography have given us scholarships for our courses in 

 the Rocky Mountains, and these have been awarded to graduates 

 of Amherst and Cornell (Iowa) Colleges, now in the Harvard 

 Graduate School, a graduate of Harvard now teaching, a senior at 

 the Massachusetts Institute of Technology, and a student at Yale 

 University.
