‘The object in the Indian plantations has been to propagate 
e species known by analysis to contain much quinine, or 
e will not grow, to raise robust trees which will yield 
quinine by cultivation. Hybrids are on the increase in 
any estates, and by careful selection from these, the value of 
the future cultivation will largely depend. 
The following table gives a list of the most important barks 
grown on the Government plantations at the present time,
