PULP AND PAPER 
A good many improvements were made in the experimental 
paper mill by the installing of further equipment and the fitting up 
of a laboratory for chemical studies and small scale experiments 
on wood and pulp. Progress has been made in the special investi- 
gations of waste sulphite liquor, beating, blotting paper, pulpwood 
measurements, and the chemistry of wood and pulp. The first sheet 
of paper was run over the experimental paper machine on May 27, 
1915, and the other paper-making equipment has been put into opera- 
tion during the year. Miscellaneous tests have been made, such as the 
beating of leather-board stock, the examination of pulp fibres sub- 
mitted by outside parties, bleach tests, testing of Canadian china 
clay, etc. 
Woop PRESERVATION 
At the close of the year the staff included a chief, assistant chief, 
engineer, and pathologist. The preservation laboratory has been 
provided with a fairly complete equipment for the study of wood 
preservatives and the preservative treatment of wood on a large 
experimental scale. In the pathological laboratory oné small room 
has been put in shape for the study of wood-destroying fungi and the 
adjoining room has been altered to serve as a fungus pit. Special 
investigations of railway ties, paving blocks, fence posts, and dura- 
bility of wood have been started. Miscellaneous work has been done 
on distillation studies of various creosotes used as wood preservatives, 
the examination of decaying timber in factory buildings, the collecting 
of fungus specimens, effect of fungus attack on wood, and reviews of 
technical literature. 
The following is a brief summary of the special studies that are 
being carried on:— 
1. Testing clear specimens. This is a comprehensive investi- 
gation designed to include ultimately all the important Canadian 
wood species and provide reliable data on their mechanical, physical, 
and structural properties. Douglas fir from three localities in Alberta 
and British Columbia has been under test since September, 1914, 
the actual testing having been completed in February of this year. 
It appears that Canadian grown Douglas fir has substantially the same 
properties as that which grows in the United States. Our forester . 
has collected the necessary logs for the testing of four eastern species— 
black spruce (including so-called ‘‘grey spruce’’) and white spruce 
from the Province of Quebec and white pine and red pine from Ontario.
