22 ANNUAL REPORT OF THE 



views, and to the maintenance of the Collection. The most im- 

 portant additions were the following: — Professor J. B. Wood- 

 worth's South American views (slides); Professor D. W. Johnson's 

 Atlantic Coast views (photographs and slides), and Mr. Wiggles- 

 worth's Montana views (photographs and slides). 



The Josiah Dwight Whitney Scholarships were awarded as 

 follows: — $100 to Wilbur G. Foye, 1 G., a student in the Rocky 

 Mountain summer course in Geology ("Geology S5"); $100, and 

 the excess of the income over $200, to Winthrop P. Haynes, 2 G., 

 for geological and geographical studies in the Rocky Mountain 

 region under the direction of Professor J. B. Woodworth ("Geology 

 S20"). 



Two students took the research course in Meteorology given by 

 Professor Rotch in the first half-year, and one of these students 

 continued his work into the second half-year. The death of 

 Professor Rotch necessitated the completion of the investigation 

 under the general direction of Professor Ward. 



In Meteorology and Climatology Professor Ward's courses were 

 given as in previous years. The removal of the instruments from 

 the roof platform to Room 43 has resulted in a more effective use 

 of these instruments. More attention is now paid to the study of 

 current weather conditions, and to their explanation. In the 

 advanced course ("Geology 20e") C. F. Brooks, 1 G., has con- 

 structed a new chart of the mean annual depth of snowfall in the 

 United States, and has also made a critical study of the snowfall 

 records of the United States. E. G. Linsley, 1 G., has studied 

 and mapped the cyclonic distribution of rainfall in California. 

 A paper on "The cyclonic distribution of rainfall in the United 

 States" prepared by W. G. Reed in this course in 1910-1911, has 

 been published (Monthly weather review, Oct., 1911, vol. 39, p. 

 1609-1615, 11 charts). 



Associate Professor J. B. Woodworth gave courses 4, 5, 8, 16, 

 and directed the research work of three students in 20c. 



Research work in Course 20c was undertaken by Mr. Haynes 

 in seismology. He perfected a graphic system of locating epi- 

 centers by means of Lambert's projection superposed on Mercator 

 Charts of the world, in the manner proposed by Professor Wood- 

 worth about three years ago. Mr. Sedgwick Smith continued 

 his work upon the geology of the Madison Range and Valley in 

 southwestern Montana. Mr. D. C. Barton reviewed the literature 

 and geological maps bearing upon the circumstances attending 

 groups of normal faults in mountain-built zones.
