The average yield of tapped trees in Negri Sembilan 
amounted to3 lbs. 2.\ ozs., which, being the average of nearly 
one million trees, is an extraordinarily high figure. This 
State has much higher yields per tree because the propor- 
tion of trees in their first tapping period is much less than 
in the other States, but this high figure is interesting as 
pointing to the averages which may be looked for in trees 
after two or three years tapping. 
An interesting tapping experiment with eight 17-year 
old trees growing pound the churchyard at Far if Biintar, 
in the Krian District of Perak, has given after one year’s 
tapping every other day an average of 284 lbs. of dry 
rubber per tree. The average girth of the trees was 54.8*7 
inches at three feet from the ground, and they had been 
growing* in unweeded land containing hiking and other 
grasses.

The Passing of Ficus elastica. 
Four years ago the question of the relative advantages 
of planting H evea braziliensis (Para rubber), or Ficus elas- 
tica (Rambong), was considered an open one, and the 
fact that the latter was a native tree and grow freely in 
Malaya induced some to prefer it to the Brazilian plant.
