In preparation for occupation by Parliament, the invertebrate 
fossils and most of the vertebrate fossils, as well as the mineralogy 
and geology displays, were placed in storage. The anthropological 
exhibits, however, were largely left intact. With the restoration of 
the building to the Museum in 1920, pressure was brought to bear 
by the National Gallery to acquire the first floor east hall for the 
exhibition of works of sculpture (mostly casts of the Elgin Marbles). 
Still regarding the presence of the Gallery as a temporary situation, 
the Geological Survey agreed to this arrangement. The first floor 
east-centre hall, which had formerly held the exhibits of inverte- 
brate palaeontology, now had also to serve for the display of several 
dinosaur skeletons, a titanothere skeleton, and numerous exhibits of 
skulls, bones, and tracks. The result was a very much overcrowded 
arrangement (Fig. 19), In spite of this, some attractive exhibits were 
installed during the twenties and thirties by Alice E. Wilson and 
Aurele LaRocque, for the invertebrates; and by C. M. Sternberg and 
L. S. Russell, for the vertebrates. Excellent art work was provided by 
Arthur Miles. In the Zoology Hall on the second floor, the systematic 
series of birds and of mammals were expanded during the twenties 
(Fig. 20). The very skilful taxidermy of Clyde L. Patch and D. J. 
Blakely, and the art work of Claude E, Johnson added much to the 
attractiveness of these displays. Meanwhile, Douglas Leechman had 
taken over the preparation of exhibits in anthropology, and he made 
these more lively and attractive, and the labels more legible (Fig. 21 ) . 
Some of the sculpture work for these exhibits was done by Mr. Patch, 
the Museum taxidermist. 
One of the laments of the Museum zoologists for years had 
been the lack of good exhibits of the large mammals of Canada. 
In 1935 Col. Harry Snyder of Montreal collected the material for 
a large habitat group of wood bison from northern Alberta. This 
group was prepared, including the taxidermy, at Col. Snyder’s 
expense, and installed by May 1936 in the second floor east-centre 
hall (Fig. 16). The following year work was begun by Messrs. 
Patch and Johnson on an adjacent group of musk-oxen; this was 
completed in 1938. By 1940 they had finished a third group, illus- 
trating the polar bear. A somewhat smaller habitat group, showing a 
family of beavers, was completed by Patch and Johnson in 1947. 
As the systematic displays of the smaller mammals in the 
Zoology Hall were crowded out by the large installations, the dis- 
plays were moved into the west-centre hall of the second floor, here 
restricting the ethnological displays to half the space they had form-
