The trees are very pm fic seed bearers. Those in the Museum 
grounds have this year yielded nearly 14,000 seeds—or, to speak 
more correctly, that number have been collected. Most of the 
trees are planted by the side of a large pet and all the ‘seeds 
which fall into it are at once carried away, as they are very light 
d float on the water. The seeds have Keet distributed, 3,000

It has recently been proved by Messrs, Curtis, Derry, and 
others that these trees will yield at least one pound per tree 
per year of clean Juge: Taking the value of the rubber at

A sample of rubber obtained from a tree cultivated in the

Mr. C. Curtis, has been submitted to Messrs. AN Levis & Kahn,

den y be mentioned that Fine Para rubber is now selling at

» beautiful rubber" from Penang should be valued at more than 
a shilling per pound less than Amazonian rubber. One explana- 
tion is that Hevea rubber cured in any other way than by the 
smoke of palm nuts is intrinsically not so good as Fine Para.
