REPORT ON THE GEOLOGICAL COLLECTION. 



By Robert W. Sayles. 



During the past year the southeast exhibition room has been 

 furnished with new cases. This room is devoted to relief maps, 

 physiographical and geological models, and meteorology. At 

 present there are on exhibition six reliefs and seven models. 

 Of these, a relief of southern New England including Massachu- 

 setts, Rhode Island, and Connecticut was purchased. Prof. 

 Robert DeC. Ward has given, in exchange for a large rainfall 

 map of the United States, a relief of Italy made to scale on the 

 natural curvature of the earth. Mr. G. C. Curtis has kindly 

 deposited a geological model of the Sentis, a high peak in north- 

 eastern Switzerland. This model was made by him at Zurich 

 under the direction of Prof. A. Heim and copied from Heim's 

 original which was awarded the gold medal at the Paris Exposition 

 in 1900. A naturalistic model of Pulpit Rock, Nahant, made by 

 Mr. Curtis, was purchased. 



In addition to the reliefs and models, there is an exhibit of 

 meteorological instruments and instructive charts, selected and 

 loaned by Professor Ward. It is planned to change this exhibit 

 from time to time. 



In the room devoted to Dynamical and Structural Geology a 

 platform for exhibiting large rock specimens has been built. A 

 glacial boulder chemically weathered into a shape approximating 

 that of an hour-glass, may be seen. This boulder was collected 

 by the Curator in 1912 at Sugar Hill, N. H. 



The room devoted to Economic Geology contains a nucleus of 

 an economic exhibit given by Prof. Charles Palache. 



On account of the embarrassment which the loss of a catalogue 

 might entail, a duplicate catalogue has been made and brought 

 up to date.
