ANNUAL REPORT OF THE 



guidance of Dr. Mansfield, fitted out at Bozeman on the 2d of July 

 and carried on an examination of the Bridger Range, and later 

 with Professor Wolff a study of the Crazy Mountains, for purposes 

 of geological instruction. Ten Harvard students took this course. 



As a matter of record it should be noted that the Department 

 of Mining and Metallurgy, which began under the auspices of this 

 Department and later formed a successful Department in the 

 Division, was this year constituted into an independent Division. 

 As a reminder of the former relations of the two Departments we 

 still retain the instruction in economic geologv, given in the 

 laboratories of the Mining Department, and also the field course 

 in geology for mining students, conducted in our laboratory. 



The Sub-committees of the Department present the following

The accessions during the year include a set of fifty-two lantern 

 slides from negatives made by Mr. Ellsworth Huntington on his 

 journeys in Central Asia, and a set of remarkable photographs of 

 water-spouts ; some views of the 1906 eruption of Vesuvius taken 

 by Mr. E. J. Saunders. The collection of slides having outgrown 

 the cases previously constructed, a large case on a quite different 

 plan has been built with a capacity for holding 13,550 standard 

 American lantern slides, 10,000 of which may be placed so as to 

 be readily accessible on the top of the case. Dr. Mansfield gave 

 a part of his time during the year to the cataloguing and care of 

 the collection. Hereafter this work will be done by Mr. Flint. 



The Committee on the Geological Museum (Messrs. Wood- 

 worth, Jackson, and Wolff) report that Mr. R. W. Sayles was 

 appointed Assistant in charge of the exhibition collections by the
