work on this subject. However work has been done along the lines 

 of collecting all the available literature dealing with the utilization of 

 waste sulphite liquor, and it is hoped that before long it will be 

 possible to publish a compilation of abstracts of such literature, thus 

 placing at the service of chemists throughout the country a fund of 

 information which would be difficult, if not impossible, for them to 

 obtain otherwise unless possessed of very extensive library facilities. 



Beating of Paper Pulp. 



A considerable amount of work has been done during the year 

 in the study of the physical and chemical reactions which take place 

 during the beating of paper pulp. This is a very important process 

 in the making of paper, particularly of the finer grades, and although 

 it is known that very involved physico-chemical reactions take place, 

 the matter has received very little close study and the process has been 

 carried on almost entirely by empirical knowledge. Some interesting 

 data has already been obtained but the results are not yet complete. 

 Owing to the impossibility of obtaining certain necessary testing ap- 

 paratus at the present time it has been found necessary to discontinue 

 this work until after the war. 



Railway Ties. 



Experimental work has been carried on dealing with the working 

 out of a suitable process for creosoting Jack pine and hemlock ties — 

 two very important species for this work which give difficulty in 

 treatment. While no process has yet been evolved which is consid- 

 ered entirely satisfactory, progress has been made and it is expected 

 that when the work now in progress has been completed the results 

 will be of considerable value. 



Acetone. 



Considerable work was done in 1916 relative to investigations of 

 acetone and the substitutes for acetone in cordite manufacture, 

 resulting in the production of suitable substitutes. This work was 

 done in co-operation with the Munitions Board and since that time 

 Dr. Bates, Superintendent of the Laboratories, has been actively 

 connected with the Board in the manufacture of acetone by certain 

 new processes. 



PuLPWooD Measurements. 



A study was made of the feasibihty of chipping, drying and baling 

 of pulpwood at or near the point of cutting. Such a procedure would
