The educational activities of a museum are extremely important. 
The results of the scientific investigations are issued in the form of bulletins. 
Efforts are also being made towards reaching the popular audience. The 
semi-scientific semi-popular lecture is one important medium and the 
lecture hall of the National Museum is the scene of great activity during 
the winter months. Further information regarding the lecture courses is 
given below. Lantern slides for illustrating lectures are loaned, and for 
these there is an increasing demand. The public has learned to look to 
the National Museum as a source of photographs of special subjects and 
there is a large demand for these for educational work and for book illustra- 
tions. The Museum is accumulating a library of moving picture films, 
and several were added during the year to illustrate the life and customs of 
the Indians. The two books, Birds of Eastern Canada and Birds of 
Western Canada, illustrate admirably the method of popular education 
by means of well illustrated and interesting publications. There has been a 
big demand for these books and they have been very influential in arousing 
and fostering an interest in the bird life of the country and its preservation. 
The Acting Director of the Museum here expresses his gratitude to 
the Geological Survey, the Entomological Branch of the Department of 
Agriculture, the Canadian National Parks, the Northwest Territories, and 
the Forestry Branches of the Department of the Interior, The Royal 
Canadian Mounted Police, and to other government departments for assist- 
ance and co-operation. He is not unmindful either of his debt of gratitude 
to many individuals and organizations, both Canadian and foreign, for 
exchanges and donations and for assistance on scientific investigations. 
Detailed reports by the various heads of divisions of the Museum 
follow. 
MUSEUM LECTURES 
A course of lectures in natural history and other scientific subjects is 
presented each winter in the lecture hall of the Museum. The lecture 
committee, consisting of H. I. Smith, M. E. Wilson, and C. L. Patch, on 
whom falls the responsibility of securing lecturers and organizing the 
course, reports a very successful year. The purpose of the lectures is to 
extend the educational influence of the Museum among children, to widen 
their knowledge, and arouse an interest in scientific subjects. They are 
delivered to the children Saturday mornings and the attendance is so 
large that the lectures have to be repeated, the first commencing at 10 
o’clock and the second at 11 o’clock. Adults have the privilege of hearing 
these lectures Wednesday evenings. Appropriate motion pictures are 
also shown. For the loan of films the Museum wishes to express its grati- 
tude to the Canadian Government Motion Picture Bureau; the Northwest 
Territories Branch, the Forestry Branch, and the Canadian National 
Parks Branch of the Department of the Interior; the Province of Ontario 
Pictures; the United States Bureau of Mines; the Canadian Forestry 
Association; and the Picture Service Corporation of New York. The small 
library of films of the Museum was also used. 
It is gratifying to report that other departments have manifested a 
willingness to co-operate with the Museum in providing lecturers. More 
than half of the lecturers of the season were drawn from the Department of 
National Defence and from different branches of the Departments of
