18 ANNUAL REPORT OF THE 



In addition to his regular courses in geology (5, 12, 15, and 16) 

 Professor Woodworth conducted a course on the elements of 

 seismology (Geology 19) to a few students at their request. In 

 RadclifTe College, he gave two half courses, equivalent to Geology 

 4 and 5 of the Harvard list. 



Professor Woodworth carried on the work of the seismological 

 station. By request the exchange of the monthly bulletin of 

 earthquakes registered at the Station has been extended to the 

 Osaka Meteorological Observatory and to the Central Meteoro- 

 logical Observatory at Tokyo, Japan, beginning January 1, 1920. 

 Mr. Randolph C. Ray, preparator, has given about an hour a day 

 to the routine work of the Station. 



As a Geologist of the U. S. G. S., Professor Woodworth gave 

 much time to the revision of a report on the geology of Cape Cod 

 and adjacent islands. The summer of 1920 was spent on Martha's 

 Vineyard. A new locality for the occurrence of the Weyquosque 

 glacial gravels was examined on the land of Mr. Ernest Flanders 

 in Chilmark and a small collection of the water-worn Miocene 

 sharks' teeth characteristic of this horizon was made. A well- 

 preserved coral or bryozoan found in a chert pebble from the 

 Miocene bed in Gay Cliffs was submitted to Mr. E. O. Ulrich, for 

 a determination of its value as a horizon marker. Other chert 

 pebbles from the same bed have been referred to a Helderberg 

 horizon. Professor Lull of Yale University kindly undertook a 

 study of the vertebrate foot print collected in the upper Carboni- 

 ferous at Attleboro, Mass., in 1916 by Mr. Fred. W. Garnjost. 



Professor Ward gave his courses as usual, with the exception of 

 Meteorology 3, which, with the approval of the President, was 

 omitted. Further progress has been made in the preparation of a 

 book on the climatology of the United States, and as President of 

 the American Meteorological Society, a good deal of time has been 

 given to the work of that Society. The summer was spent in the 

 preparation of a presidential address. The Laboratory teaching 

 collections are in good condition. 



Professor Raymond gave Palaeontology 1 and 2 in the new 

 form. The former was arranged to illustrate matter of more 

 general interest regarding the progress and evolution of life; the 

 latter takes up the subject of invertebrate Palaeontology from a
