Professor Ward gave courses B, 1, 2, 19, and 20e, as in the previ- 

 ous year. Much time was spent in extending, reclassifying, and 

 labeling the collection of meteorological lantern slides and photo- 

 graphs. These are in excellent condition. Somewhat over 100 

 slides were purchased, to form part of the teaching materials in 

 Geology 2 (Geography of South America). Two large charts of 

 the pressures and generalized winds of the world, and a number of 

 photographic enlargements, have been added. In the advanced 

 course (Geology 20e) the subjects investigated by students included 

 a reduction of the temperature data of Boston for the period 1871- 

 1908; a revision of the rainfall types of South America; the prac- 

 tical application of the cyclonic unit in climatological tabulations; 

 the conditions of occurrence of cold waves; the meteorological 

 controls of the seismograph tracings. In connection with his work 

 on the temperature data of Boston, Mr. Andrew H. Palmer, a 

 graduate student of meteorology and climatology, laid out the 

 plan for, and supervised the construction of, a plaster of Paris 

 model showing the mean hourly temperatures for each month for 

 Boston, on the basis of 38 years' observations. This model is 

 unique of its kind, and will be placed in the Geological Museum. 

 It was constructed with the aid of a grant from the income of the 

 Sayles (Geological Museum) Fund. Professor Ward gave a public 

 lecture at Columbia University, March 2, 1909, on " Climate in 

 some of its relations to man." During the year the laboratory was 

 critically inspected by Mr. A. B. Wiggin, Assistant Director of the 

 Argentine Meteorological Office. 



Professor Woodworth reports that he was in charge of the Shaler 

 Memorial Expedition in South America during the first half-year. 

 He spent the time from the 8th of July to the latter part of No- 

 vember in the states of Sao Paulo, Parana, and Santa Catharina, 

 in the examination of the boulder-bearing beds occurring just 

 below the Permian plant horizons. From Rio de Janeiro he pro- 

 ceeded via the Straits of Magellan to Talcahuano on the west coast 

 of Chile, making a study of changes of shore-line, particularly 

 about Concepcion and Corral. While in Chile he attended the 

 Pan-American Congress as a delegate from the University, and 

 served on the board of the Association of American Universities. 

 In Brazil Professor Woodworth was very substantially aided by the 

 government through the Director of the Geological and Minera-
