24 ANNUAL REPORT OF THE 



assist students working under his direction in the Rocky Moun- 

 tains. 



No student took the research course in Meteorology, 20/, with 

 Professor Rotch, and his time was occupied in directing the work 

 of the Blue Hill Observatory. 



In addition to his regular courses (Geology B, 1, 2, 19, 2GV), 

 Professor Ward gave three lectures on the geography of South 

 America in the course, "Business 14." Under the general direc- 

 tion of Professor Ward, Mr. William G. Reed, Jr., Assistant in 

 Meteorology, spent much time in the equipment of the Students' 

 Meteorological Observatory, in regulating the instruments, and 

 in taking regular observations. The Station is now well equipped 

 with most of the ordinary instruments, and gives opportunity 

 for effective work on the part of students. Several investigations 

 carried on by members of the course in Advanced Climatology 

 have been published, as follows: 'The study of phenomenal 

 climatology" and "South American rainfall types," by W. G. 

 Reed, Jr. (Quart, joum. Roy. met. soc, January, 1910, vol. 36, 

 Xo. 153, p. 39-47; 49-59); "Model of the chrono-isotherms of 

 Boston, Mass., U. S. A." (Ibid., April, 1910, p. 181-184) and 

 'The temperature conditions of Boston, Mass." (Monthly weath. 

 rev., June, 1910, vol. 38, Xo. (5, p. 973-976), by Andrew H. Palmer. 

 Professor Ward spent part of the summer in Brazil, making a 

 study of the economic climatology of the Sao Paulo coffee district. 



With the assistance of Professors Davis and Wolff, Professor 

 Woodworth gave the lectures in Geology 4, and also conducted 

 courses 8, 16 and 20c. Two half-courses in elementary geology 

 were given, in the Museum, to students in Radcliffe College. 

 Professor Woodworth, with the assistance of Mr. J. W. Eggleston, 

 gave the summer course in field geology in Montana, which was 

 completed by 17 students. Mr. G. M. Flint accompanied the 

 party as collector. Professor Woodworth has devoted consider- 

 able time to the completion of reports on field work, and to the 

 management of the Seismographic Station. A small collection of 

 Middle Cambrian trilobites was purchased. 



Professor Johnson gave courses A, 9, 10, and, in cooperation 

 with Professor Davis, 2i)a. In the summer he supervised the 

 field work of Mr. X. J. Bond, who made a five-weeks' study of 

 shoreline changes in the Quincy-IIingham area. Under the
