to be assured, as it is expected that a price oi 12 cents per gallon will 

 be realized in the future. Tomlinson urges the establishment of plants 

 for the production of wood-waste "molasses" at the larger sawmills and 

 the sale of this product to centrally established co-operative fermenta- 

 tion and distillation plants, which must of necessity be under the rigid 

 supervision of the Internal Revenue Department.

Paper manufacturers, who during the early 

 Interest part of this year quite generally refused to show 



in much interest in the recovery of turpentine from 



Spruce the waste sulphite liquors, now seem to be eager 



Turpentine to install the necessary apparatus for this pur- 



pose. It was first pointed out by Klason, in iqoo, 

 that spruce turpentine consists mainly of cymene, which can readily be 

 converted into toluol and cumene. which are at present so urgently 

 needed in the manufacture of tri-nitro-toluol and benzoic acid. A re- 

 cent paper prepared by Schorger, of the Madison Laboratory of the 

 Forest Service, states that various mills have reported a recovery of 

 0.36 to i.o gallons of turpentine per ton of pulp. Schorger finds that 

 sulphite turpentine, consisting largely of cymene, can be used for the 

 production of carvacrol, a compound which is similar in properties to 

 thvmol, and toluol.

STATISTICS AND HISTORY 



From an abstract of a lecture by Duchesne on 

 British "P>ritish Timber Supplies," which is also a plea 



Timber for the development of a forest policy, we glean 



Supplies the following facts : 



During the last 60 years the annual consump- 

 tion of "timber" in Great Britain had increased from 3.5 to 10.5 cubic 

 feet per capita, and the total imports during that period had increased 

 fivefold, home supplies being almost neglected. The change which has 

 been brought about l)y war conditions is strikingly illustrated by the
