land than the other. 
This last statement of the Commission thus qualified is in complete 
accordance with what has always been understood with regard to 
Hevea brasiliensis and we have no reason to doubt the © strict 
accuracy of the statement (see Wickham, Para Rubber, pp. 5 and 
61), that the whole of the Hevea seed originally introduced to the 
East came from trees which grew under the conditions thus indicated 
by the Brazilian Commission.

Sir, 
I wave the honour to thank you for your letter dated 
April 30th, with reference to the varieties of Hevea brasiliensis, and 
for your clear explanation of the question. 
- ~ Perhaps the attached letter from Dr. C. J. J. van Hall with 
reference to the trees at Pasir Oetjing (which were said to be the 
only ones in the Hast belonging to the “black” variety) may 
interest you. 
I am, &c.,

Dear Mr. Lewron Brain, 
THE result of the investigation at Pasir Oetjing about the 
“black variety ” is as folllows :— . 
All the Hevea-trees at this plantation originate from seeds from 
the F.M.S. (Valombrosa, &c.) except the oldest ones, planted 8 years 
ag o difference is to be seen between the first mentioned trees 
and the Hevea-trees on other plantations in Java. As regards the 
8 years old trees, these are about 1500 in number, they have been 
saith from Godefroy-Lebeuf (Paris), who got the seeds from 
rasil. 
Dr. Rutgers went to Pasir Oetjing to investigate these Heveas. 
Their : penemecce is a little different from that of the common type 
the bar’ i i h 
the bark is thin, The yield is poor and decidedly below the 
average. In the leaves there is as much variation as always among 
Hevea-trees and nothing particular could be found.
