Dear Sir, — Please find herewith a letter from Mr. C. E. S. 
BAXENDALE of Jugra, which I venture to think will prove very in- 
teresting reading to many of your readers. 
The question of the maximum yield of our Para trees, if adver- 
tised in this manner, ought to attract attention front far outside the 
Malay Peninsula ! 
I am dear Sir, 
Yours Faithfully, 
E. V. CAREY.

YIELD OF PARA-RUBBER TREES. 
Jugra Estate. 
Selangor , October 21st, 1902. 
The Agricultural Bulletin. 
Dear Sir,- — C an you tell me what is the record yield of a Para 
rubber tree for one year? 
By this mail I have despatched to Liverpool,; parcels containing 
26 lbs. of clean rubber and 3 lbs. of scrap, the result of two months 
(exhaustive) tapping of two trees growing in Mr. SALISBURY’S gar- 
den at Gapis Estate. Perak. The trees are said to have been planted 
by Sir Hugh LOW 19 or 20 years ago, on what Mr. SALISBURY 
considers to be the poorest soil possessed by the Kuala Kangsar 
Plantations Co. 
Tree No. r . — Girth at one yard from ground .89 inches,' Never 
previously cut. I worked this tree from three channels (beginning 
with a three cornered chisel and going on with my pruning knife) 
and the first days yeild was just one ounce of rubber. During the 
next five days 1^ fbs. was the result. Then the yeild rapidlv in- 
creased, the daily average for ten days exceeding half a pound. 
The maximum, twelve ounces, was reached at the tvvelth day from 
commencement. At the end of July, I left Gapis, and Mr. 
SALISBURY continued the work with occasional intervals until Sep- 
tember 1 8th.

Except that we worked this from two channels instead of three 
the method was the same. '
