ways very keenly interested in its 

 Avork and never too busy to give his 

 •counsel when asked by officers of the 

 Association. His death leaves a gap 

 in the ranks that it will be difficult to 

 fill. 



Mr. AYhite's business interests and 

 cares were practically confined to his 

 official duties. In religious life he 

 was an Anglican and for many years 

 he was one of the chiefs of the ^Masonic 



Order, attaining the office of Grand 

 Master of the Grand Lodge of Canada 

 in the year 1911-12. He is survived 

 by his widow, one son and four daugh- 

 ters. In social life he was a delight- 

 ful acquaintance and a firm friend 

 and the Canadian Forestry Associa- 

 tion is but part of that wide circle 

 which will keenly feel his loss and 

 which otters its sympathy to the mem- 

 bers of his familv.

been tested in commercial sizes in the large 

 machines. Much valuable information has 

 been obtained from these tests and results 

 will be ready for publication in the near 

 future. 



Timber Physics. 



Considerable equipment, including micro- 

 tome, microscopes, photomicrographic ap- 

 pjaratus, projection lantern, cameras, elec- 

 tric ovens, autoclave, balances and so 

 forth, has been obtained for this division. 

 The work has to do largely with the de- 

 termination of physical and structural pro- 

 perties of wood by the testing of moisture 

 content, specific gravity, percent spring- 

 wood, percent summerwood, percent sap- 

 wood, percent heartwood, fibre dimensions, 

 cell structure, microscopic characteristics 

 and fungus infection. There has been con- 

 siderable study to learn the relation of 

 microscopic structure of wood to penetra- 

 tion by preservatives and other liquids. 

 General botanical studies are also made. 

 All the photographic work is done by this 

 division, including the making of micro- 

 scopic slides, photomicrographs and lan- 

 tern slides of wood sections and pulp 

 fibres, as well as miscellaneous photo- 

 graphs, copies, enlargements, etc. Studies 

 have been made to improve the methods 

 of wood i<leutification. Investigations are 

 in progress on the relation of vapor pres- 

 sure and shrinkage to the moisture content 

 of wood. 



Pulp and Paper. 



Special attention has been given to the 

 equipping of a thoroughly modern semi- 

 commercial experimental paperniill and it 

 is safe to say that when all the equipment 

 is in place this mill will be without an 

 equal in any of the centres throughout the 

 world where experimental work of this 

 kind is in progress. A sjjecial Fourdrinier 



paper machine has been installed, the 

 machine being about 75 feet in lengtli and 

 turning out a sheet 30 inches in width. The 

 machine is flexible in its adjustments and 

 attachments and is designed to make prac- 

 tically all grades of paper. A single 

 beater of 40 lbs. capacity and a double 

 beater of 60 lbs. capacity have been in- 

 stalled with interchangeable basalt lava 

 and steel rolls with individual motor drive 

 to each roll. The remaining equipment, 

 which is now in place, includes three stuff 

 chests, riffler, screen, four pumps, five 

 motors, two paper testing instruments, 

 Erfurt sizing system and a variety of small 

 apparatus. Sulphite and soda digesters 

 and other equipment will be installed in 

 the near future for the manufacture of 

 Avood pulp by chemical processes on a satis- 

 factory scale. Preliminary work has been 

 done on several pulp and paper investiga- 

 tions. Queen 's University has co-operaced 

 in research on the chemical composition of 

 waste sulphite liquor, which is produced 

 in such large quantities by our papermills. 



Wood Preservation. 



A new Division of Wood Preservation 

 was organized in October, 1914. The scope 

 of this division includes the study of wood 

 preservatives and methods of treating 

 wood to prolong the life of railroad ties, 

 pacing blocks, telegraph poles, posts, 

 piling, trestle timber, mine props and 

 structural timber in general. A study of 

 wood destroying fungi has also been un- 

 dertaken as well as methods of fireproof- 

 ing wood. A certain amount of equip- 

 ment in the form of retorts, pumps, mo- 

 tors, air compressor and so forth have been 

 obtained for the carrying on of experi- 

 mental work. Particular attention is be- 

 ing paid to the subject of railway ties in 

 Canada.
