and other problems in which a knowledge of the local geology is a 

 factor in the working out of a solution. Two days were spent in 

 July in an examination of the lower course of the Connecticut 

 River between Middletown and Saybrook, as well as in a visit 

 to Haddam and vicinity, in an attempt to determine the possible 

 association of the well-known slight earthquakes of that district 

 with recent faults. No signs of Postglacial faulting of the bed- 

 rock were discovered. Some progress was made in gathering 

 materials for a comprehensive paper on the relation of folded 

 chains to fault-block mountains. 



Mr. Harold C. Durrell gave a set of the publications of the 

 U. S. G. S., and Lieut. John L. Pultz has deposited a wireless 

 receiving set for the purpose of obtaining time signals for the 

 Seismographic Station. It is hoped that this service, when work- 

 ing, will relieve the Astronomical Observatory of our almost daily 

 request for a comparison of the rate of our seismographic service 

 clock, a service most generously given for the past ten years. 



In addition to his regular courses, Professor Ward gave a series 

 of sixteen lectures on tropical climatology to the graduate students 

 in the School of Tropical Medicine of the Harvard Medical School. 

 On May 9th, he gave a lecture on Meteorology in relation to the 

 art of war at the General Staff College, Washington Barracks, 

 D. C. As President of the American Meteorological Society, 

 Professor Ward gave an address on Climate and health, with 

 special reference to the United States, in Chicago, December 29, 

 1920; and presided at the winter and spring meetings of this 

 Society, of which he was reelected President for the year 1921. 

 In April, he attended the meetings of the American Geophysical 

 Union in Washington. Spare time during the winter was devoted 

 to further work on a book dealing with the climates of the United 

 States. This work was continued during the summer. The 

 teaching collections in meteorology and climatology have been 

 improved by the addition of some thirty photographic enlarge- 

 ments. 



Professor Raymond continued his investigations of the strati- 

 graphy of the Ordovician of the southern Appalachians, under a 

 grant from the Shaler Memorial Fund. Two months were spent 

 in studying localities in Virginia, Tennessee, Alabama, and Ken-
