To 0. B. Markham, Esq., C.B., E.B.G.S., &c., 
India Office, London. 
Sir, 
I have the honour to submit, as directed by you, for the 
information of Her Majesty’s Secretary of State for India, a Deport 
on the caoutchouc of commerce, the methods of collecting it, the 
plants yielding it, their geographic distribution, climatic conditions, 
and the possibility of their being cultivated and acclimatized in 
India. 
I have arranged my Deport in the following manner : — Part I. 
Sources of supply (Botanical and Geographical), and Part II. 
The cultivation and acclimatization of the plants yielding 
caoutchouc. 
I also send herewith a set of specimens of the different com- 
mercial varieties, which I beg to present to you for the purpose of 
being placed in England or India, wherever you may deem that 
they may be likely to prove most useful for purposes of reference. 
I have the honour to remain, 
Your obedient Servant, 
James Collins, E.B.S.E.
