According to the Chemiker Ztg. 1 ), there are to be found in San 

 Domingo pine forests which are extraordinarily rich in turpentine, and 

 a local company is already engaged in manufacturing this product. 

 A certain variety of pine, known as Suaba, is said to be so rich in 

 rosin that the branches are used as torches. 



We have on various occasions reported on methods for obtaining 

 oil of turpentine from pitchy wood 2 ). A new process of this kind, 

 which is being employed in British Columbia for the utilisation of 

 wood as well as of saw mill refuse, employs electricity — by which 

 probably is meant the electric furnace. 



According to an American Consular Report 3 ), a demonstration was 

 given at which two cords of wood were worked successfully for "tur- 

 pentine oil", tar, oil, resin, pitch, and charcoal. The theoretical result 

 promises the following rich yield: — per cord of resiniferous wood 

 at $ 5, yielding chemically pure "turpentine oil" as well as the by- 

 products mentioned above, of a total value of $ 24.70, the cost of 

 production amounts to $ 12. The profit therefore should be $ 12.70, 

 which appears to be confirmed by a number of experts familiar with 

 the process and the production. It is stated that the yield per cord 

 of wood is as follows: — 



Rosin ..... 60 lbs. 



Tar oil 20 gallons 



Charcoal . . . . 1300 lbs. 



With regard to the last-named products, their usefulness as a wood 

 preservative and in the manufacture of gunpowder is specially referred 

 to. It is alleged that large quantities of suitable wood are available 

 at low prices, and it is also stated that the plant has recently been 

 increased to a capacity of 40 cords. 



Apart from the question in how far a product of this kind, which 

 should merely be termed pine tar oil, can be considered a sub-
