MUSEUM OF COMPARATIVE ZOOLOGY. 21 



pared and published a biographical notice of the late Prof. R. S. 

 Tarr. A paper on the installation and management of a seismo- 

 graphic station, and another on field geology were also written 

 for publication in current journals. He continued the work of the 

 Harvard Seismographic Station, issuing mimeographed monthly 

 bulletins of earthquakes recorded at the Station, and establishing 

 an exchange of data with the principal observatories in Germany, 

 Austria, Australia, etc. A detailed report of the work of the 

 station will be found in a forthcoming Bulletin of the Museum. 

 Mr. G. M. Flint performed the ordinary routine work of the 

 changing of records, etc., in the instrument room. 



In July, 1913, Professor Woodworth, being relieved of the charge 

 of the Rocky Mountain course in field work, attended the Inter- 

 national Geological Congress in Canada. 



Professor Graton, on half-time appointment, conducted Geology 

 10 (4 students) and Geology 20b (4 students). Much of his time 

 was occupied with organizing and directing an investigation on the 

 secondary enrichment of the copper ores of the United States. 

 With a large staff of expert assistants he has begun the task of 

 assembling in the Museum the great amount of ore and rock ma- 

 terial from the leading mines. The field work will continue several 

 seasons. The very considerable cost of the undertaking is de- 

 frayed by the generous help of the copper-producing corporations 

 throughout the country. During the summer Professor Graton 

 carried on geological work in the copper mines of Butte, Montana, 

 and in the winter he made professional visits to the mining districts 

 of Bisbee and Globe, Arizona. He presented papers before the 

 American and Canadian Mining Institutes, the Geological So- 

 ciety of Washington, and the Southwestern Conference of Mining 

 Geologists. 



Professor Raymond gave Palaeontology 1 (4 students) ; Palaeon- 

 tology 20 (2 students). In the research course Mr. Winthrop P. 

 Haynes prepared an article on the Brachiopoda of the Upper 

 Devonian of Montana, and Mr. Donald C. Barton finished a paper 

 on A new genus of the Cheiruridae, with descriptions of new 

 species. 



During the Easter recess, Professor Raymond, accompanied by 

 Mr. Winthrop P. Haynes, took a small party of students to some 

 of the typical exposures of fossiliferous Palaeozoic strata in eastern 

 New York. During the three days occupied by this trip, the 

 party collected from most of the formations from the Upper 

 Cambrian to the Middle Devonian.
