22 ANNUAL REPORT OF THE 



the geological formations of the vicinity of New York City has 

 been added to the laboratory equipment in Course 5. Mr. Lahee, 

 in connection with his work in Course 20c on the geology of the 

 Kingston area in Rhode Island, made a collection of rocks from 

 the metamorphosed coal measures of the Carboniferous system. 

 Mr. H. E. Merwin, J. D. Whitney Scholar for 190G, deposited 

 the fossil Pleistocene shells found by him in Vermont among the 

 materials available for research. One graduate student worked 

 during the year on the geographic conditions attending the ex- 

 tinction of Mastodon amcricanus; another carried on local field 

 studies on the details of joint distribution in relation to directions 

 of rock tension and compression. 



The elementary courses offered to Radcliffe students show a 

 falling off in attendance. The addition of laboratory and field 

 work to the elementary lecture course on dynamical and structural 

 geology given to these students in the Museum has been accom- 

 panied by a reduction in attendance from 34 young women in 1903 

 to 4 this year, and none this year elected the complementary course 

 in historical geology in the second half-year. In the case of 

 these courses young women are required to perform the same labo- 

 ratory and field exercises as Harvard men, but their schedule of 

 hours is necessarily unsatisfactory. They have the use of the 

 laboratory when it is not needed for classes or sections of classes 

 composed of Harvard students; so, too the choice of hours is 

 restricted by the instructor and his assistants to their own free 

 hours, thus giving rise to a greater number of conflicts in the 

 choice of hours for the Radcliffe student than is the case with the 

 student in Harvard University taking an equivalent course. The 

 courses in geology taken by Radcliffe students are designed pri- 

 marily as a part of a college course, and only occasionally does a 

 student take the courses with the expectation of teaching elementary 

 geology in the secondary schools, or as a foundation for teaching 

 physiography. The Department sets aside no special room or 

 collections for Radcliffe students in geology. It is understood 

 that undergraduates of Harvard College and Radcliffe shall not 

 work at the same time in the same room unless under special 

 conditions, and then only when an instructor is present. 



Professor Woodworth continued his work for the N. Y. Geo- 

 logical Survey during the year. In August and September, 1907,
