WOLFRAM.

the range of granite hills and mountains that separates Lower Burma 
from Siam, and stretches north from the Pakchan river bounding 
the Mergui district on the south, through the whole Tenasserim divi- 
sion, to a point at least as far north as Karenni in the Southern Shan 
States. Many of these placer deposits have been stated at different 
times to contain wolfram. A complete account of these occurrences 
cannot be given here, but will be given later in the article on tungsten 
in the ' Mineral Resources of India ', when this is published. It is 
sufficient to say here that wolfram has been recorded from Karenni, 
and the districts of Amherst, Mergui, and Tavoy, but never in situ. 
This present year (1907), however, Mr. J. J. A. Page of the Geological 
Survey has found wolfram in situ in the parent rock. The locaUty is 
in a 15-foot wide reef on North Hill near Maliwun ; of two specimens 
brought from here by Mr. Page, one shows the wolfram in a quartz matrix 
without any other minerals, and the other consists of quartz containing 
wolfram, cassiterite, and a Httle copper pjTites, the wolfram being in 
allotriomorphic crystals up to 1 inch long. The other locality is 6 miles 
south of Inner Bokpyiii in the same district, the rock in which the wolfram 
occurs bemg that known locally as ' kra ', which is a decomposed tour- 
maline-granite containing tinstone. In this case Mr. Page detected the 
mineral only after panning the rock for tinstone, the wolfram not being 
visible in the hand-specimen. 
A specimen recently received from Mr. Kellerschon was found, on 
being tested by Mr. G. G. Narke of Nagpur in the Geological Survey 
laboratory, to be wolfram. One piece is three inches long. In Decem- 
ber 1907, I was able to visit the locality of the find — Agargaon in the 
Nagpur district — ; the mineral occurs in quartz veins interbedded with 
mica-schistfi, and with associated tourmaline-schist. l
