MUSEUM OF COMPARATIVE ZOOLOGY. 23 



Geography of the war area, given in the Geological Museum, and 

 the other at the joint meeting of the American Geographical Society 

 and the Association of American Geographers in New York, 

 April 9, 1915. He also gave two lectures on the geography of 

 South America in History 57. 



In the winter, Professor Ward completed a chapter on Meteor- 

 ological Observations for the forthcoming Handbook of the 

 Harvard Travellers Club, and a paper on the climatic subdivisions 

 of the United States. He devoted his summer to work on the 

 climatology of the United States, in connection with a* book which 

 he is preparing on this subject. 



Professor McAdie reports that the expense of maintaining the 

 Blue Hill Observatory has been met by the income from the 

 endowment fund provided by the Founder and former Director, 

 the late Professor Abbott Lawrence Rotch, supplemented by gen- 

 erous aid from Mrs. Rotch (a gift of $1800) and Mr. George 

 Wigglesworth (a gift of $500). Special fire-proof cases for the 

 records were provided by Mr. I. Tucker Burr. For the coming 

 year some additional provision should be made to enable the 

 Observatory to carry out certain experimental work in both the 

 lower and higher strata of the air. 



There have been no changes in its staff or general policy and 

 the past year was one of quiet, cumulative effort along existing 

 lines of work. The European war has disarranged all Inter- 

 national cooperation; complete restoration of the good feeling 

 and comity which previously existed among meteorologists is 

 problematic, as two different schedules have been announced by 

 Russia and Germany. 



The buildings and general equipment are in good condition 

 Much needed improvements in connection with the water supply 

 and plumbing have been made. The building is now lighted by 

 electricity. 



Instruction has been given to three graduate students, two of 

 whom came from the Massachusetts Institute of Technology. 

 Two courses were given : Meteorology 20a for graduate students ; 

 and Meteorology 6 for undergraduates who have taken certain 

 other courses. 



Aerological observations were continued as in previous years. 

 The regular observational work has been continued and a series 

 now covering a period of thirty years is complete. The observa- 

 tion of pressure, temperature, humidity, precipitation, sunshine, 

 day and night cloudiness, and other meteorological phenomena
