western Germany and on the western battle front was particularly 

 opportune in adding to the supply. 



Wood waste and sulphite lye are being used in Germany for the 

 manufacture of ethyl alcohol. A cubic foot of wood is said to yield 

 about a quart and a half of alcohol. 



A bulletin of Kew Gardens advises the growing of Rhamnus 

 frangula in coppice as specially profitable for the manufacture of char- 

 coal fit for fireworks. Before the war the scarcity of this material had 

 raised the price to $50 and $70 per ton. A sandy clay of medium 

 quality is suitable. The plants grown in nursery are set out in rows 1 

 foot apart, 6 inches in the row, and when 9 to 10 inches high are 

 coppiced. 



The use of the motor car in connection with fire fighting, according 

 to District Forester G. P. Melrose, of the British Columbia Forest 

 Branch, saved in his work for the fire season of 1916 around $950 ; this 

 amount being figured out by comparing what each trip with the motor 

 would have cost in time and money if carried out using existing means 

 of travel, namely, forty-five days of the District Forester, twelve days 

 of a ranger, and fourteen days of a ranger on a motorcycle. Besides, 

 the greater efficiency, due to saving time, must be taken into considera- 

 tion.— Cawadiaw Forestry Journal, March, 1917, p. 995. 



The University of California Forestry Club proposes to publish a 

 monthly magazine of its own under the title California Forestry. Its 

 object is mainly to "get acquainted," but articles of technical import, 

 and, indeed, "on all phases of forestry," are also intended to be pub- 

 lished. The subscription price is to be $1, and of the 700 subscriptions 

 necessary to keep the magazine running it appears that 500 have 

 already been guaranteed. 



District 5 estimates that during 1916 over 700,000 people used 

 the California National Forests for recreational purposes.
