found it impossible to contract for a supply to serve their needs. This 

 has induced some of them to go into the manufacture of box lumber, 

 and several sales of National Forest stumpage have been made direct 

 to these consumers of lumber. It will be interesting to watch the his- 

 tory of these concerns, particularly if conditions such as those in the 

 lumber industry several years ago again develop. 



As a silvicultural operation it may become necessary to kill trees 

 that cannot be profitably exploited, to give light to others. An Indian 

 forester has made the discovery that this is most easily, cheaply, and 

 efficiently done by employing Atlas Preservative (composition not 

 stated). It kills the tree in a fortnight, being applied with a brush 

 after light girdling — that is, cutting through the outer bark. One gallon 

 will kill many trees, at the same time preserving the wood, even against 

 white ants, as the preservative penetrates the whole tree.- — Indian For- 

 ester, 1 91 8, p. 23. 



The district forester at San Francisco has recently received an appli- 

 cation from a firm located near the Angeles Forest for 100 tons of 

 leaves of the yucca plant, locally known as Spanish dagger. Up to 

 this time this plant has been considered as absolutely worthless and has 

 been regarded as a considerable fire menace. The fiber obtained from 

 the dried leaves will be used in the manufacture of brooms, which will 

 be sold for about $6 per dozen in comparison to about $8 per dozen for 

 corn brooms. One ton of yucca fiber will produce about 800 brooms. 



One of the many devices used by the Canadian Forestry Association 

 :o reach the school children of Canada is through a series of attrac- 

 tively printed "forest talks." Each address is accompanied by several 

 large cards containing illustrations, the latter being passed about the 

 class-rooms at the close of the reading. School teachers in all parts of 

 Canada are making use of these periodical addresses on forestry. 



Arguing that the coal supply will be short for the next two years, 

 and that hardwoods are needed in the distillation works to produce 

 acetate used in the manufacture of munitions, and moreover needs to 

 be seasoned for fuel, the Minnesota Commission of Public Safety calls 

 attention to the dead tamarack as a satisfactory fuel upon the basis of 

 ten years' experience.
