Part I.] Puran Singh : Turpentine Oil and Indian Rosin. 71 
Evidently there is a great room for the expansion of this indus¬ 
try in India in order to meet the requirements of the Indian market, 
which, with the extension of railways and various industrial under¬ 
takings, seem likely to gradually increase unless a cheap and efficient 
substitute can be found. It is, however, improbable that the Indian 
oil would be able to replace some of the best grades of the American 
oil unless better qualities of oil from Finns Khasya , P. Merkusii and 
F. excelsa are also brought in.
