section for the study collections, including a large series of dovekies, gulls, 
ducks, and geese that were received in a dry, salted state. Forty-nine 
large mammals were prepared and tanned, including bear, wolf, seals, 
deer, caribou, and musk-ox. Three hundred and thirty-one specimens 
were loaned for nature study work in schools and art work. 
Forestry Branch, Department of the Interior, has made a beginning 
of exhibition of certain forest products, and has filled one large case with 
two exhibits: (1) The Manufacture of Wood Pulp, illustrating the ground- 
work, sulphate, sulphite, and soda processes; (2) Some Products of Wood 
Pulp, including rayon thread and weaves, wallpaper, twine, rope, fibreware, 
wall-boards, and artificial wood. Part of the material for four large tree 
exhibits has been shipped in but not yet installed. 
The Honorary Curator of Insects, Mr, Arthur Gibson, Dominion 
Entomologist, has aided in the installation of a case of Silk Products, the 
bulk of the material being supplied by the General Silk Corporation. 
As a result of field work by members of the staff, a considerable num- 
ber of additions have been made to the study collections, and much material 
obtained suitable for subsequent mounting. The material, which comes in 
a fresh or semi-prepared state, requires considerable attention from the 
taxidermy section. 
The identification and arrangement of current collections and the 
assembling of data obtained from field notes form an important feature of 
the work and the results are embodied, from time to time, in the Museum 
reports and scientific journals. The officers of the Division of Biology are 
prepared to identify and return Canadian specimens of mammals, birds, 
reptiles, or amphibians, which are sent in a fair state of preservation and 
with sufficient data in regard to locality, data of collecting, and sex if possi- 
ble. Where possible the Museum would be pleased to have duplicate 
specimens sent for deposit in the National collection. The Chief Botanist 
will only attempt to determine plants when properly pressed, showing 
roots, stems, leaves, and, if possible, flowers or fruit, and it is requested 
that one or two duplicates of each form be sent for dissection and for 
permanent preservation in the National Herbarium. 
The National Parks of Canada, Department of the Interior, through 
the Commissioner, Mr. J. B. Harkin, has kindly continued to send in many 
specimens of large game, predatory or fur-bearing mammals from the 
various national parks. The North West Territories and Yukon Branch, 
Department of the Interior, through Mr. 0. S. Finnie, director, and the 
members of various detachments of the Royal Canadian Mounted Police, 
through the Commissioner, Colonel Cortlandt Starnes, have continued 
to send in valuable materials from the Far North, which are very acceptable 
to the Museum. The area of the Dominion of Canada is so large that the 
only hope we have of obtaining needed material from many districts is by 
donations from interested friends and public-spirited sportsmen and 
travellers. 
The Hudson’s Bay Company, the largest establishment engaged in 
the fur business in the British Empire, has for some time been interested in 
having studies made of the periodical fluctuations in the numbers of wild 
animals in the districts where the company operates trading posts. Although
