THE GARDNER COLLECTION OF PHOTOGRAPHS. 



The Gardner Collection of Photographs has been increased by 

 a considerable number of views, secured chiefly by purchase, under 

 the direction of a committee consisting of Messrs. Woodworth, 

 Daly, Griswold, and Ward. In the latter part of April an exhibi- 

 tion of about a thousand photographs, selected from the collection 

 to exhibit different subjects in geology and geography, was made 

 on the lower floor of Massachusetts Hall, attracting a satisfactory 

 attendance of students and teachers, and bringing to the attention 

 of many persons for the first time the existence of the considerable 

 resources of the department in this direction. The most notable 

 addition to the collection, a series of views taken by W. H. Rau 

 along the line of the Lehigh Valley Railroad, and presented by 

 Mr. Charles S. Lee, general passenger agent of that road, was 

 received just in time to be displayed in the exhibition.
