fifty students; N. H. 14 (Paleontology), ten students ; N. H. 15 
(Historic Geology), four students; N. H.16 (Field-work), eight 
students. | 
The students in the higher courses necessarily demand much 
labor on the part of the instructors. There is great need of an 
additional instructor in this department, who should have charge 
of the students’ cabinet, and take a share in the field instruction, 
especially in the courses in Paleontology. 
A considerable part of the time of the instructors in this de- 
partment has been given to the study of the geological ground 
accessible for the purpose of field teaching. This is a necessary 
work, and one demanding much labor. From its results it appears 
that within fifty miles of Boston ground may be selected which 
will illustrate many important problems in the practical study of 
Geology. Nine students have been provided with summer work 
in the field. ‘Two of these are engaged on the Northern Trans- 
continental Survey; three are studying classic localities in Eu- 
rope ; the others are at work at various points in this country. 
At present, this summer teaching is only given to those who have 
pursued the preliminary work in the College Classes.
