Contributions to the history of the Gutta producing trees of the Malay Peninsula, 
Tile following varieties of Gutta are enumerated in the order of their respective 
vaiite in Perak and Salaugor.

Lst.— Gutta-soosoo. Of this I was unable to get any samples or specimens of the tree 
producing it, and the only information I could glean, concerning it. was that the tree is 
entirely destroyed except in the inf erior of Perak, that the gutta is firmer in texture than 
Gutta -tabau and contains a little oil. 1 his must not be con founded w ita l he Grutta-soosoo, 
of Borneo which is a Caoutchouc or JEtubber. 
2nd. — Gutta-taban. This is the Gutta-percha of commerce, and the product of a tree 
described in 1S37 by Sir Win. iiooher under the uame of tsonandra Gutta. 
The Pungkulu of Kroli informed Mr. C. J. Skinner that in Perak there are two sorts, 
alike in foliage and general appearance, differing only in the colour of the flowers, one haying 
white and rhe other red flowers, which are known to the Malay s by the names of ngiato 
* putih” and “ngiato me rah." but the products of both trees are called Gutta-taban. 
Isonandra Gutta is 'most abundant on Gunongs Meem and Sa-youg and Bujong 
Malacca ; a few large trees still exist on Gnnong Bubo and the lhaipeng range, rfinalf 
plants from 1 to 8 feet are abundant on rite granite formations in Perak up to 8,500 feet 
elevation. 
To procure the milk, the tree is cut down at 5 or 0 feet from the ground and the top 
cut off immediately, where it becomes too small for ringing, which the. natives _ say causes 
the tree to yield a much larger quantity of milk, and the bark is then ringed with ygolos 
at intervals of 5 to 15 inches. The milk which continues to flow for about an hour is 
collected in vessels made of palm leaves or coeoanut shells and then boiled for about an hour, 
otherwise it becomes brittle and useless. 
One of the principal gutta merchants of Perak informed Mr. Low. that a large tree 
will give TO catties of gutta, but I am inclined to think that this is an exaggeration, usinreph 
to numerous enquiries among the men in the jungles I was told that from 5 to 15 catties 
is about the average quantity obtained, and never more than 20 catties. 
The natives of Perak recognize no particular season for collecttmg the gutta, nor was 
1 able to glean any information as to whether or not the trees yield more in abe season than 
in another ; but I expect that the gutta in the wet season contains a larger quantity of wider 
and requires more boiling to drive it off, 
[ have no statistics relating to the supply or export of the various sorts of gun a of 
Perak, but I hope to be able soon so lay them before you. 
Prom Klang 83 pels. 83 ctys, have been exported from January to November, J 87 n so 
that it is probable that over 700 trees have been destroyed to furnish this quantity during 
that time. 
It is generally — if not always, exported in the shape of oblong balls with a loop at the 
upper end through which a piece of rattan is put to facilitate its being carried through the 
jungles. They vary considerably in weight, but about 10 to 25 catties is about the average 
weight per ball, _ r , 
£ n colour it is greyish white with a slightly red hue inside and bright umber brown 
outside but the colour varies according to the quantity of bark and other impurities

If the cultivation of Isonandra Gutta is attempted, plants not larger than !. foot high 
should be procured from the jungles and lifted very carefully as they have always a long 
tap-root, and if this is broken or injured, the plants, even if they survive— take a long time 
to recover. _ . ,, _ , . 
I believe the seeds are ripe in the dry season, and they might be procured from trees 
cut down then, hut they should be sown at puce, because, if allowed to get dry tuej would 
doubtless lose their germinating power. ... T , , , ,
