ture at Denver, Col. (based on thermographic records lent by the 

 Harvard College Observatory), the evolution of the Mississippi 

 River, the physical geography of Wisconsin, the physical ge- 

 ography of Arkansas, and the rivers of Connecticut ; the last 

 three subjects being treated by students who were familiar with 

 the States mentioned, either from residence, or from geological 

 field-work within them. 



Advanced work in Field Geology has been done by two gradu- 

 ate students, under the direction of Professor Davis, in connection 

 with his study of the Triassic Area of Connecticut for the United 

 States Geological Survey ; besides which there has been special 

 work in the Laboratory by Mr. L. S. Griswold in compiling a 

 map of the Triassic Area from the reports of various assistants ; 

 and by Mr. S. Ward Loper in arranging and classifying an ex- 

 tended collection of Triassic fossils, which has since been sent 

 to the National Museum in Washington. 



The office of the New England Meteorological Society has 

 been maintained in the Laboratory of Physical Geography for 

 several years past. The monthly Bulletin of the Society, con- 

 taining reports from about one hundred and fifty observers, has 

 been issued regularly from this office, with the assistance of Mr. 

 J. Warren Smith of the United States Weather Bureau, who 

 was especially assigned to this work by the Chief of the Bureau, 

 and with the support of the Director of the Harvard College Ob- 

 servatory, the Bulletin being published in the Annals of that 

 institution. In March, 1892, it seemed advisable to transfer the 

 work of collecting and publishing monthly meteorological re- 

 ports to the New England Weather Service, established at that 

 time for this purpose, the service being under the direction of 

 Mr. Smith, and having its office in the rooms of the Weather 

 Bureau, in Boston. Professor Davis has thus been relieved of 

 the responsibility of superintending the preparation of the So- 

 ciety's Bulletins. At about the same time, the publication of 

 the American Meteorological Journal was removed from Ann 

 Arbor, Mich., to Boston ; Professor M. W. Harrington, who had 

 founded the Journal and edited it from the beginning, hav- 

 ing removed to Washington on his appointment as Chief of the 

 Weather Bureau, and his place as editor being assumed here by 

 Mr. R. DeC. Ward, Assistant in Physical Geography. Mr. Ward 

 has also undertaken a study of thunder-storms in New England
