Some difficulty was found in ensuring the purity of the latex and 
its collection from different places under similar conditions, and the 
above results must be regarded as preliminary* Further investiga- 
tion is in progress. 
It will however be noted that the latex from the higher portion 
of the trunk are poorer in rubber than the latex from lower down — 
at the same time the proportional amount of resin in the latex ap- 
pears to decrease.

Tengah Bark. 
From District Officer, Bindings, 
To H. N. Ridley, Esq., Singapore. 
20th May , 1904. 
Mr. BURN-MURDOCH asked Mr. BORGES, Forest Ranger, Din- 
dm<'S, to write the attached memorandum re Tengah Bark for the 
Agricultural Bulletin : it is condensed from a report on the Man- 
"Tove growth in the Dindings River. The dye obtained being 
preferred to ‘bakau’ bark dye. There has been a very large quan- 
tity of it exported from here, so much that the “tengah” lias been 
cut in preference to “bakau ” owing to the valuable bye-product 
furnished bv the bark which also strips more easily.
