744 EXPERIMENT STATION RECORD. 



his Investigations relative to the possibilities of various western species of pine 

 for turpentine production. 



Some experiments conducted in California show a yield of oleoresin from 

 western yellow pine about 12 per cent greater than that obtained from southern 

 yellow pine in average operations in Florida, the comparison being made on the 

 same period of time for both sections. It is believed that the turpentine pro- 

 duced in California will be satisfactory for industrial purposes. 



The low yield from western yellow pine in Oregon precludes its use for tur- 

 pentine at the present time. Jeffrey pine in California yields somewhat less 

 oleoresin than western yellow pine and the principal constituent, heptane 

 (abietene), can not be used as turpentine. Heptane is used to a considerable 

 extent in the manufacture of various medicinal products and it is believed a 

 further market may be developed for it as an extractive in place of petroleum 

 hydrocarbon fractions now used. The rosin from both of these pines is of high 

 grade. Thus far the commei-cial exploitation of oleoresin from digger pine, 

 single leaf piiion, lodgepole, and sugar pine is considered to be impractical.

Joint annual report of the forestiy branches for the year 1912-13 (Bd. 

 Agr. and Fisheries [London], Joint Ann. Rpt. Forestry Branches, 1912-13, pp. 

 82, pi. 1, figs. 2). — This comprises the first annual report of the forestry branches 

 recently constituted in the Board of Agriculture and Fisheries and the Office of 

 Woods. 



The introductory chapter deals with the general attitude toward foresti-y and 

 afforestation in England and Wales. The work of the forestry branches is then 

 briefly reviewed. A historical note is given on the management of the crown 

 forests and woods, together with notes on the individual woods and information 

 relative to the school for working foresters and the wood distillation works on 

 the Forest of Dean. The report concludes with a statistical review of the tim- 

 ber trade of the United Kingdom. Information relative to technical advice in 

 forestry and the area of woodlands in England and Wales for 1913 is appended.
