tree yields not only a har “ite very durable timber, but also the 
local guttapercha, known as ba he timber, one of the hardest 
and densest in the Colony, is ae heavy to float, and it is exported 
only to a slight extent.

The yield per tree varies a good deal, not only in regard to size, 
but also the her ea of the year. The largest trees may yield as 
much as 0 pounds of balata, whereas a young tree a foot in

necessarily limits the area to about 20 square miles, for the 
bleeders do not care to go many miles in, as they almost invariably 
bring out their milk to the riverside to sun or air dry it. A 
number of grants of the same size can be taken out together, or in 
other parts of the country by one person. 
96. Rubber.—There are probably several species of trees yielding 
indiarubber to be found in the Guiana forests. One, the Hatie 
(Hevea spruceana) is closely allied to a tree yielding the Para 
rubber of commerce, the most important caoutchouc tree now 
existing. The Hatie is found in the upper Shasta of the Essequebo 
and Mazaruni rivers, and probably yields at of the crude rubber 
sometimes received from that region. is also found in some 
districts on the Ponoi river. Mr. Jania calculates that from 
a large pos several pounds of Soe might t be produced.

arge twining plant known locally as “ Macwarrieballi,” and 
determined to be Forsteronia gracilis was received at Kew in 
1888. It was shown that if the plant from which this rubber was 
prepared existed in any quantity in the interior of the Colony, the
