Mr. Sayles; also a small collection of rocks from southern Brazil 

 collected by J. B. Woodworth. 



Professor Woodworth gave illustrated lectures on certain general 

 aspects of his South American voyage before the Unitarian Club 

 of Watertown and the Boston Society of Natural History. He 

 remained in Cambridge during the vacation in order to devote 

 himself to the working up of his materials and the writing of 

 reports. At the same time he conducted by personal conference 

 and field inspections where conveniently near Cambridge a course 

 of research in glacial geology and shore-line phenomena. Mr. 

 John H. Cook of Albany, as a member of this course (S20c), made 

 a detailed map of the drift deposits in the Charles river valley on 

 the western border of the Boston quadrangle, definitely determin- 

 ing the glacial stream channel now followed in part by Cheese 

 Cake Creek. Mr. W. P. Haynes mapped deposits on the southern 

 border of the same quadrangle, while Mr. H. C. Durrell searched 

 the coast of Maine for the upper marine postglacial limit. 



While in Santiago, Chile, Professor Woodworth, through the 

 courtesy of Count Montessus de Ballore, inspected the observatory 

 at that time in process of construction and installation near that 

 city. 



Professor Johnson reports that he gave courses A, C, 6, and 9 

 and, in the absence of Professor Davis, conducted course 20a. In 

 the latter course four students prepared papers on the following 

 topics: — The development of Winthrop Beach and its vicinity; the 

 physiography of the Plum Island district; an experimental study 

 of the physical conditions producing folded cross-bedding in rocks ; 

 the physical and economic geography of Canada. Geology 9 

 (Geographic influences in North America) was given for the first 

 time. The equipment of the geographical laboratory has been 

 augmented by the purchase of a rack for displaying mounted photo- 

 graphs used in laboratory exercises; two atlases; a number of 

 large wall maps and charts; numerous topographic sheets, geo- 

 logic folios, lantern slides, and photographs. Messrs. Basil Gavin 

 and Johnson presented a series of photographs of European land 

 forms. 



On August 25-28 Professor Johnson gave four lectures on the 

 "Geography of the western United States" before the Vacation 

 School of Geography at Oxford. During the winter he com- 

 pleted editorial work on a volume of Davis's Geographical essays;
