while the 'supply of long-leaf is fast melting away. A product 

 very similar to turpentine can be obtained also from pinon 

 pine, another tree common in the Southwest. 



Careful tests made by the department have shown that the 

 yield of turpentine and rosin per season from Western yellow 

 pine in Arizona is only two-thirds that. from the Southeastern 

 pine, the difference being due to fact that the season of flow 

 in the West is about 25 weeks, and in the South about 33 

 weeks. During the Civil War, when turpentining operations 

 in the South had virtually ceased, some operations were car- 

 ried on in California to meet local needs. But with the return 

 of the Southern product to the California market, the West- 

 ern operations were abandoned. 



The results of a chemical examination of the oils of West- 

 ern yellow, pinon, digger, sugar, and loge-pole pines which 

 have just been published by the forest service in an official 

 bulletin show the possibilities of the rosin and turpentine 

 from Western yellow and pinon pines as a supplement to the 

 present supplies. Economic problems of markets, transporta- 

 tion, and labor remain to be solved. Information as to how 

 the 'forest service secured the yields upon which the analyses 

 were based is given in another bulletin on the possibilities of 

 Western pines as a source of naval stores. 



Western hemlock, says the Department of Agriculture, de- 

 serves a better opinon and more general use than it now ob- 

 tains. Intrinsically it is among the most important of West- 

 ern woods. 



The wood of Western hemlock has generally been consid- 

 ered an inferior one chiefly because of the prejudice created 

 by the name, which has caused it to be identified with East- 

 ern hemlock. Tests by the forest service, however, show it 

 to have 88 per cent the strength of Douglas fir, one of the 

 country's chief construction timbers. In fact it is often mixed 

 with Douglas fir and used for the same purposes. 



The wood is practically free from pitch, has a handsome 

 gain, takes paint and stain well, and works smojothly. It is 

 suitable for sash and door stock, furniture, interior finish, 

 framing, flooring, boxes, barrels and pulp. In bridges and tres-
