kiln dried, but this is quite unnecessary. If the nuts are too large, or the cake 

 requires it, they can, of course, be passed through the cake-breaker. 



"The grinding is rather a slow process, and the cost works out about 2S. gd. 

 per coomb or sack. The cost of collection is 4s. per sack, and of carting and 

 turning is. 3d., so that the total cost is 8s. per sack. 



"It is important that the food, as soon as it comes from the mill should be 

 mixed with the bran ; this dries it, and prevents heating. It should immediately 

 be spread over the granary floor, say, 3 inches deep, and turned every day. 

 The rations should be served to the horsemen from the granary every day, 

 as otherwise it would probably be carelessly stored by them and then would 

 certainly heat and spoil." 



A Canadian inventor has solved the problem of burning green wood 

 in logging operations, both in yarders and locomotives. It consists of 

 a machine to create a forced draft. The nose of the machine is intro- 

 duced into the fire-door opening of existing steam boilers, and opera- 

 tions start at once. Six stationary plants are already built in British 

 Columbia carrying out this principle — burning green wood. 



The Canadian Forestry Association this summer adopted the modern 

 way of making propaganda by outfitting a traveling exhibition car with 

 instructive objects and educational photographs. Motion pictures and 

 lectures formed part of the attraction. The main object was to create 

 public interest in fire protection. 



Cordwood is to be cut by the War Department on the Pisgah Na- 

 tional Forest at the rate of 500 cords per day. A labor battalion of 

 1,200 negro soldiers is now camped in the forest and ready for work, 

 which will be begun as soon as the officers in charge get their bearings, 

 and also the proper equipment with which to do the work. Shipment 

 of the wood will be over the Car Lumber Company's railroad, which 

 at present is used to its capacity in transporting tanning material for 

 the War Industries Board. 



The Minnesota Station has issued a bulletin (No. 168) which gives 

 data on soil requirements, growth, yield, and distribution of white 

 spruce, together with approximate returns which may be expected 

 from young seedlings or plantations. Suggestions are made regarding 

 the possibilities of private investment and a rational system of taxing 

 forest land. The main features of the Massachusetts forest taxation 

 law are quoted.
