knowledge of the subject. Ordinarily, the income of any given 

 year is to be used for paying the salary and expenses of the instructor 

 in charge of the course. Any unused part of the income is to be 

 available, on the recommendation of the Geological Department, 

 for defraying the travelling expenses of any student or students 

 who may need such help for the taking of the course. If no 

 student is in actual need of money for his expenses in such a course, 

 the unused part of the income is to be given to a meritorious student 

 to meet the expenses of research work in geology, geomorphology, 

 palaeontology, petrography, or genetic mineralogy, under the 

 supervision of the appropriate department of the University. This 

 gift puts this summer course on a permanent basis, and releases 

 the funds which have lately been devoted to its maintenance. 



The seismograph, the installation of which was noted in last 

 year's report, has been in operation during the year. A special 

 report upon the seismographic station, prepared by Professor 

 Wood worth, who has charge of it, is printed on p. 28-32. The 

 Shaler Memorial Expedition to South America was brought to a 

 successful conclusion in January, 1909, and a brief report upon it 

 will be found on p. 23-24. 



The Geological Conference was maintained as in previous years. 

 Papers on a large number of subjects of general interest were pre- 

 sented by instructors and students. Mr. George M. Flint has 

 continued to render extremely satisfactory service as laboratory 

 assistant, and has done a large amount of work upon the Gardner 

 Collection of photographs and lantern slides under the general 

 charge of Mr. R. W. Sayles, who acted as Curator. The card 

 catalogue has been completed. Meteorological slides, to the num- 

 ber of 217, and South American slides to the number of 116, 

 selected for the collection by Professor Ward, have been numbered, 

 labeled, and catalogued. About 100 new slides of European views 

 have been similarly treated. Photographs of meteorological sub- 

 jects, to the number of 198, have been numbered, labeled, and 

 catalogued. Folders for storing them were purchased, and these 

 photographs are now in standard order. Sets of upwards of 40 

 each, of Scandinavian and Italian views, were selected by Mr. 

 Sayles for exhibition in the Geological Museum. The state of 

 the Gardner Collection on July 1, 1909, is shown in the subjoined
