Museum. The committee is very desirous of securing some 

 means of regularly exhibiting certain parts of the collection 

 to the public. Mr. E. G. Sherwin, Price-Greenleaf aid, acted 

 under Mr. Smith's direction in the care of the lantern slides. 



Dr. Jaggar continued his work in charge of the advanced field 

 course in Geology. Fourteen students completed surveys, in 

 the autumn, of the southern part of the Lawrence quadrangle 

 and the eastern part of the Framingham quadrangle. Dur- 

 ing the second half-year this class investigated the complex 

 problems of the region about High Rock in Melrose, one division 

 of the class completing a large-scale topographic map and inscrib- 

 ing thereon the geology. Mr. LaForge rendered efficient assistance 

 in this work, and completed a thesis on the Geology of Somerville, 

 Mass., which was presented for the degree of Doctor of Philosophy. 

 Special studies of large areas in the vicinity of Boston were made 

 by Messrs. D. C. Bard and F. M. Wilder. Mr. Bard made a re- 

 connaissance geological map of portions of the Lowell and Law- 

 rence quadrangles, and Mr. Wilder, of the Framingham quadrangle.' 

 These studies are preparatory to more elaborate work by future 

 classes. In collaboration with Professor Crosby, of the Massa- 

 chusetts Institute of Technology, arrangements were made with 

 the United States Geological Survey, whereby Dr. Jaggar and 

 Professor Crosby will jointly produce a Boston City folio showing 

 the geology of the Metropolitan district of Boston. Three stu- 

 dents from the Institute of Technology joined the Harvard 

 class in experimental geology in the spring, and two of these 

 carried on advanced field work in the Middlesex Fells. In 

 February, Dr. Jaggar gave a course of six lectures at the Lowell 

 Institute on the " Caribbean Volcanic Eruptions and their Bearing 

 on Vulcanology." 



Mr. Read gave the course in Elementary Physiography. He 

 also acted as assistant in Geology 6 and 14, and lectured on 

 Elementary Physiography at the Institute of Technology during 

 the first half-year. 



The following publications by officers of the department were 

 issued during the year: —
