the work of this course in the second half-year as members of 

 Course 23. Mr. G. C. Curtis also prepared for publication a brief 

 report on the elevated shore-lines of Monhegan Island, Maine. 

 Instruction in the elements of Geology was given, during the 

 first half-year, to 38 students of Radcliffe College, and in 

 Elementary Field and Laboratory Geology to 15 Radcliffe students 

 during the second half-year. Mr. Goldthwait assisted in the 

 latter course, and conducted all but one of the excursions. 

 Partly to supplement the work in Glacial Geology, and partly to 

 make use of a large number of instructive field localities south 

 of Boston, Professor Wood worth has arranged to give, in alternate 

 years with Geology 16, a new half-course on the Carboniferous 

 Period. 



The rock collections in the laboratory of General Geology were 

 increased during the year by the purchase of a set of the Oscar 

 Rohn collection of rocks illustrating the geology of the Lake 

 Superior district. Mr. P. S. Smith donated to the laboratory his 

 own collection of rocks from the Black Hills of South Dakota, 

 including specimens from the Archaean up to and through the 

 Jurassic. The Department is also indebted to Mr. George D.x 

 Keyser for specimens of crystalline rock salt from the lake beds 

 near Gunnison, Utah. Sixty pieces of pumice from the streets of 

 St. Pierre, Martinique, together with one volcanic bomb from 

 Mont Pelee, were purchased from Ward, of Rochester, for the 

 laboratory. A Locke hand-level and a camera were added to the 

 field equipment, and seven enlarged photographs from negatives 

 of the New York Geological Survey were framed and placed on 

 the walls of the Museum. An additional collection case, holding 

 91 standard museum trays, was erected in the hallway for storage 

 purposes. 



At the request of Professor Stanislas-Meunier, of the Museum 

 of Natural History in Paris, Professor Woodworth sent to that 

 institution for temporary exhibition during April, and for perma- 

 nent deposit in the collections, a small exhibit representing some 

 recent studies of trails in the Saratoga sandstone. As a member 

 of the New York State Museum, Professor Woodworth continued 

 his field investigations during September, 1903, in New York, 

 over parts of Canada, from Ottawa to Beloeil Mountain, Quebec, 

 and in parts of Vermont. During the winter and spring, reports 

 were prepared upon the Surface Geology, including the elevated 

 shore-lines of the Mooer's quadrangle in Clinton Co., New York,
