16 ANNUAL REPORT OF THE 



The opportunities for research were, of course, quite limited, 

 but Professor Atwood continued in charge of investigation and 

 the preparation of a report on the Physiography of the San Juan 

 Mountains of Colorado. 



Professor Woodworth spent the month of August, 1918, in 

 writing certain parts of a text-book of military geology and geog- 

 raphy, under the auspices of the Committee on Geology and 

 Geography of the National Research Council, for the use of the 

 S. A. T. C. The regular work of the seismographic station was 

 maintained during the year up to the end of May, and some 

 advance made in the preparation of a report on Cape Cod and the 

 islands, for the U. S. Geological Survey. In November, 1918, 

 Professor Woodworth was appointed Geologist in the U. S. G. S. 

 for special work in New England, and during the year was elected 

 a member of the newly organized International Geophysical 

 Union in connection with seismology. 



At the end of June, 1919, Professor Woodworth went to Bozeman 

 in charge of the Summer School in Geology (Course 5) which was 

 attended by twenty-four students, for six weeks, counting as a 

 whole course, because of war conditions. A few specimens col- 

 lected in Montana were added to the teaching collections. 



Professor Raymond reports that a set of models of extinct 

 reptiles by C. W. Gilmore of the U. S. N. M, formed the principal 

 addition to the palaeontological collection. 



Professor Raymond will offer an elementary course in palaeon- 

 tology to students of Radcliffe College in the year 1919-1920. 



Mr. R. C. Ray continued to act as preparator of the Division, 

 giving much time to the military courses.
