MUSEUM OF COMPARATIVE ZOOLOGY. 23 



Professor Woodworth completed the manuscript of his report 

 on the Shaler Memorial Expedition to Brazil and Chile ; directed 

 the field work of Mr. Haynes in the search for fossils in the Car- 

 boniferous region about Providence, R. I., and carried on the work 

 of the Seismographic Station during the year. 



In the summer of 1911 Professor Woodworth conducted a field 

 course in geology in Montana after which he visited southern 

 California, the Grand Canon in Arizona, and the Winding Stairs 

 Mountains in eastern Oklahoma. At Telihinah, in this last region, 

 he studied the striated stones and boulders in the Caney shales, 

 a report on which was presented to the Geological Society of 

 America in December, 1911. 



The storage facilities and the means for the work of the seismo- 

 graphic station and for the preparation of geological reports have 

 been increased. 



Assistant Professor D. W. Johnson gave his courses during the 

 first half-year, and during the second half-year was on leave of 

 absence for the continuation of his study of shorelines in connection 

 with the Second Shaler Memorial Expedition. 



Assistant Professor Raymond reports that four students took 

 the advanced course in Palaeontology ("Geology 20d") as a whole 

 course in the second half-year. 



Dr. F. H. Lahee reports that Geology 12 was conducted accord- 

 ing to the plan adopted the year before. The students spent the 

 first month in class work at Pondville, under the immediate super- 

 vision of the Instructor. During the rest of the first half-year 

 each student worked on a small area (five or six square miles). 

 A written report on this area was required at the end of the term. 

 During the spring the students were given long, narrow, north- 

 and-south strips across the Boston Basin, thus enabling them to 

 gain a fair idea of the structure of the entire Basin. Each student 

 conducted the class and the Instructor through his area once in the 

 season. Through the generosity of Mr. R. W. Sayles, Dr. Lahee 

 was able to spend the summer of 1911 in field work in northern New 

 Hampshire. An area of about 250 square miles was studied. 

 The course, Geology 4, was given by Dr. Lahee in Radcliffe Col- 

 lege. Dr. Lahee also served as Assistant in Geology 5, under 

 Professor Woodworth. 



Mr. W. P. Haynes was Assistant in Geology 4, and gave Geology 

 5 in Radcliffe College.
