assistance was received from Mr. H. W. Dutch, a member of the 

 Sophomore Class, who, as the recipient of a Price-Greenleaf Scholar- 

 ship, spent four hours a week in doing clerical work. 



Courses 10 and 11, the former relating to Mining Geology and 

 the latter to Geological Surveying as carried on in mining work, 

 were given during the year by Mr. H. L. Smyth. For lack of room 

 elsewhere, the lectures in these courses were given in the Petro- 

 graphical Lecture Room. Field-work was prosecuted in the vicinity 

 of the University. 



The course in Research (Geol. 22) was directly supervised by 

 Mr. Griswold, who spent much of his time in the fall and spring 

 in the field with students. The attention of the students was 

 mainly directed to the structure of the rocks in the Boston basin 

 and the contiguous areas of Carboniferous rocks in the Narragan- 

 sett Basin. The valuable results obtained will be embodied in 

 future publication. Shore phenomena in Eastern Massachusetts 

 and metalliferous deposits in Essex and Berkshire Counties were 

 also investigated. In the spring an excursion was made to Katah- 

 din Iron Works, Maine. One student conducted a series of experi- 

 ments with wave and current marks with a view to publishing the 

 results. Mr. T. Wayland Vaughan, graduate student, carried on 

 during the year an investigation of the Eocene fauna of Louisiana, 

 and prepared a report for publication. At the beginning of the 

 present government year, he was appointed assistant palaeontolo- 

 gist of the United States Geological Survey and was assigned to 

 duty in the southwestern States. Mr. Alfred Brooks, graduate 

 student in geology, was also appointed assistant geologist in the 

 same organization and proceeded in mid-summer to the southern 

 Appalachians. Mr. F. P. Gulliver accompanied Mr. Gilbert of the 

 Survey in an expedition to Colorado, and Mr. F. C. Schrader, 

 another graduate student, was employed as a temporary assistant 

 of the Survey in southern New England. Mr. Merrill, graduate 

 student of year before last, has presented for publication in the 

 Bulletin of the Museum of Comparative Zoology a paper on flint 

 sponge spicules from the cretaceous of Texas. 



Additional Courses. 



For many years a considerable share of the time in Courses 4 

 and 8 has been given to the subject of glacial geology, and with a
