work, the Curator gave two lectures, one in the hall of the Society 
and the other in Cambridge, and the proceeds were sufficient to meet 
the expenses for a time. 
The Museum has this year been visited on days when the public 
is not admitted by 17 teachers and 476 pupils, representing 18 
schools. 
Teaching in the Museum. 
This department still continues to be active, but is entirely 
dependent upon the generosity of the same lady who has heretofore 
supported it. The following talks and courses have been given by 
Mr. A. W. Grabau. In September short talks upon various subjects 
were given in the Museum, the attendance usually numbering from 
ten to twenty persons. Beginning with October and continuing 
through November, a course of nine lectures on the elementary 
principles of organic evolution was given on Saturdays at 11 o’clock. 
The course attracted attention, and the lectures were frequently 
reported in the newspapers. The average attendance at each lecture 
was about eighty persons, the number not infrequently reaching one 
hundred. This course has done more than any other to attract 
public attention to this department of our work. On Wednesdays 
during October and November a course of eight lectures on the great 
ice age and its work was given at 11 o’clock. The average attend¬ 
ance at these was about thirty. Altogether this has been the most 
successful season for this department. The one thing necessary to 
give it wider usefulness is advertisement. The short notices in the 
papers are too slight to become widely known, and many persons 
who would be glad to hear the lectures do not know of their 
existence. 
Lecturing in the Museum was resumed on the first Saturday in 
April, 1897, but no regular course was begun until the 17th of that 
month. 
On Wednesdavs at 11 o’clock lectures on the surface of the earth, 
its rocks, soil, and scenery are given ; attendance at these averages 
about thirty persons.

The Curator has expended considerable time in preparing labels 
for this department which will be put in place next year. The
