Office Work 
R. M. Anderson completed the manuscript for a museum bulletin on 
“Methods of Collecting and Preserving Vertebrate Animals.” This is 
primarily intended to give necessary instruction in modern methods to 
field workers in the interest of the museum and collectors of scientific 
material, as well as to give valuable information to trappers, hunters, 
farmers, or nature lovers who may wish to collect specimens for themselves 
or to preserve specimens in shape for identification. Thousands of valu- 
able specimens are lost or destroyed every year on account of ignorance of 
their scientific value or lack of knowing how to take care of them. This 
work is illustrated by forty-six line drawings by Mr. C. E. Johnson. Work 
was continued on a report on “Animal Life and Life Zones of Southern 
British Columbia”, covering the four seasons’ work (1927-1930) of museum 
field parties along the International Boundary from the strait of Georgia 
to the Rocky mountains. Some progress has been made on the “Check- 
List of Canadian Mammals”, the completion of which depends largely on 
intensive work in previously neglected regions of the Dominion. The 
same contingencies have operated on the progress of work on the projected 
illustrated and descriptive book on the “Mammals of Canada” which has 
been under way for several years. 
Mr. P. A. Taverner completed the manuscript and drawings for a 
bulletin on “Water Birds, Game Birds, and Birds of Prey of Canada,” 
and work was begun on the compilation of a new descriptive book on 
“Birds of Canada,” combining the essential features of his previous works, 
“Birds of Eastern Canada”, and “Birds of Western Canada”, which are 
now out of print. 
Progress has been made by C. L. Patch, chief taxidermist, in preparing 
and installing biological exhibits in the museum hall. The following birds 
and mammals, either in groups or as single specimens, have been placed 
on exhibition in the systematic habitat series. Mammals: polar bear cub 
(Banks island); red squirrel and young, grey and black squirrels (Ontario), 
eastern woodchuck (Ontario). Birds: chestnut-sided warbler and young 
(Ontario), nighthawk (Ontario); golden plover and young (Churchill, 
Man.); American scoter (Ottawa river), starling (Ontario); sage grouse 
(Saskatchewan). In the taxidermy section 169 birds and mammals were 
prepared for the study collections. The exhibits containing sections of 
67 forest trees of Canada were re-labelled and re-arranged. Progress has 
been made in preparing an exhibit of several species of the most important 
large Canadian forest trees, with sections of the trunks. A total of 314 
mammals, birds, amphibians, and reptiles were loaned for nature study 
and art work in the schools. 
Considerable work in re-arranging insect exhibit? has been done by 
Mr. W. B. Hutchings, of the Entomological branch, Department of Agri- 
culture, under direction of Mr. Arthur Gibson, Dominion Entomologist,
