eastern hillock (No. 4) it is about 200 yards, i^etween hillocks 
1 and 2, and 3 and i, there is no ore exposed, so that it is possible that 
there are here three ore lenticles on one line of strike (hillocks 2 and 3 
lorming one lenticle). On hillocks 3 and 4 the outcrop of the ore- 
band was measured as 20 — 2r> feet wide, and at the only place where 
a decided dip was seen (hillock 3> it was (50'^ to vertical to the west- 
north-west. The ' country ' was nowhere exposed, unless a small outcrop 
of mica-quartz-schists on the low ground between hillocks 3 and 4 be 
considered to represent it ; a few yards to the east of hillock I biotite- 
gneisses are seen dipping at SO"^ to W. 35° N. under the ore-band. 
On hillock 1 the ore-band, which is not well exposed, consists princi- 
pallv of ore containing in places more or less of the 
bronze-coloured mica. The ore is a very fine- to 
medium-grained mixture of braunite and psilomelane ; and one piece 
collected contained a band of the very magnetic manganese mineral 
(vredenburgite) found at Beldongri. A sample was taken both from the 
blocks on top and from the pieces down the slopes of the hillock, where a 
few shallow pits had been dug in the talus. The analysis made at the 
Imperial Institute showed : —

indicating the presence of about 25 % of braunite. 
On top of hillock 2 are some fairly large blocks of ore cropping out. 
Some of the ore is apparently of good quality, but 
a much larger proportion of it is slightly spoilt by 
garnet, felspar, or bronze-coloured mica. There is also a fair quantity 
of spessartite. Besides this there are a number of outcropping blocks of 
Pyroxene-microcline- coarsely crystallized white microcline-rock streaked 
rock. and patched with brown and black owing to the 
deposition, along cleavage and other cracks, of manganese oxide, and to
