BIG RUBBER TREES IN THE BOTANIC 
GARDENS. 
Plate I. 
By H. N. Ridley. 
In the year 1894, the forest inspector J. Goodenough planted some 
rubber seedlings in a wood behind his house in the Botanic Gardens. 
This wood is on the slope of a hill running down to the main road 
and rather steep. It had been planted up by Mr. Cantley about 
1884 with Albizzia tnoliiccana, Eugenia grandis and pseudosubtilis 
and other trees and had additions in the form of various trees of the 
character of Belukar jungle. The wood was very thick as there was a 
good deal of under-growth too. The soil is a stiff clay. The rubber 
trees were quite forgotten for about ten years, and when found were 
crowded up with other trees, but had made surprisingly rapid growth. 
Three were on the top of the hill where it was a little flatter and at a 
distance of 8 feet, and 18 feet respectively apart. The tallest No. 1277 
was measured a few days ago. It had grown considerably higher than 
the surrounding trees and was conspicuous from afar. Its height was found 
to be no less than a hundred feet, while in girth at three feet from the 
ground it measured 72 inches. The stem is smooth and straight with- 
out a branch for a considerable height. The other two were less tall, one 
having lost a portion of the top (No. 1276). It measured, at three feet 
from the ground 60 inches. The third gave a measurement of 79 
inches. 
On the slope the trees lessen in girth in proportion to the steep- 
ness of the hill, the slopes of which show signs of a strong rush of 
water during rains. The whole wood is full of seedlings from these 
trees, although for some years past it has been the custom for the 
seed collectors to gather up the fallen seeds. 
The usual height given for a full grown para rubber tree is 70 
feet, and the tall tree (No. 1277) is certainly the record in height, 
and yet it is but fourteen years of age. This is a most instructive
