able is provided to inquirers. 
LANTERN SLIDES AND PHOTOGRAPHS 
Sets of lantern slides, mostly coloured, on natural history subjects, are 
being added to regularly, and may be obtained on the same terms as the 
motion picture films. A large collection of photographs have been taken 
by officers of the National Museum and Geological Survey and furnish a 
basis for the Museum’s service to the public. 
SALE AND LOAN OF SPECIMENS 
Many standard collections of minerals and rocks, as well as mineral 
and rock specimens, were distributed to schools and prospectois. Other 
specimens, because of their fragility, are not so easily shipped to places 
outside Ottawa, but extensive use is made by the schools oi Ottawa and 
vicinity of specimens of birds, animals, and Indian relics set aside foi this 
purpose.

industry and travel, and other subjects were given under the auspices ot 
the National Museum. The lecture committee, consisting of M. E. Wilson 
(chairman) C. L. Patch, and Miss M. Godwin (secretary), reports a most

the lectures were given on Saturdays at 10 a.m. and 11 a.m. for children,
