MANGANESE DEPOSITS OF INDIA : DESCEIPTIVE. [PaRT IV : 
lower level. I did not follow this second band throughout its length, but 
it seemed, at the points where I examined it, to be as good as the eastern 
band. Where, however, the western band gives rise to two hillocks 
at the southern end there is, in addition to ore, also a fair quantity 
of spessartite- quartz-rock (gondite) with large garnet crystals. There 
is also a certain amount of garnet and quartz to be found in the eastern 
band. This ridge reaches its highest point at the northern end, where it 
is about 130 feet above the ' Kareekussa N. ' to the north. Sample 
No. 50 was collected all along the outcrop of the eastern band and 
consisted mostly of the fine-grained braunite-psilomelane mixture with 
a certain quantity of the speckled ore showing the usual sooty black 
spots and lead-like patches of psilomelane. The analysis (see page 704) 
shows that the average ore contains about 20 per cent, braunite and 
80 per cent, psilomelane. i 
Where the road from Hirapur to Bawldongri crosses the ore-belt 
Tl r r' E ist H'U between the Northern Hillocks on the north, and 
West and East Hills on the south, four bands are 
seen cropping out, as marked on the map. The most easterly of these 
rises to the south up the hillock shown immediately to the north of 
East Hill and from there on to East Hill itself, where it forms the western 
ore-band. On this hillock there is also a hematite-quartzite composed 
of granules of hematite in a rather glassy quartz-rock containing a little 
muscovite ; there are also some blocks of a coarse muscovite- quartz- 
rock probably of pegmatitic origin. Where this ore-band reaches the 
East Hill it consists of good hard grey ore. I did not, however, follow 
up this band, seeing it again only on the low ground at the south end of 
East Hill, where it consists of the speckled ore. The east band runs 
along the top of this ridge, but is not always exposed. It consists of good 
and poor ores and spessartite-quartzite. At the northern end, where 
the ore is probably in sufficient quantity to be worked, I took sample 
No. 48 from the outcrop, a few pieces being also added to the sample at 
various other parts of the outcrop. The sample consisted of the usual 
hard grey braunite-psilomelane mixture and the analysis of it (see 
page 704) indicates the proportions to be 27 per cent, braunite to 73 per 
cent, psilomelane. On the low ground between East and South Hill, 
where the Kaiparia-Bawldongri road crosses, three ore-bands crop out. 
The most easterly of these is 30 yards wide and consists of speckled 
ore shewing garnet, quartz, and the altered chocolate amphibole ; and 
where this band, a little to the north, forms part of the barrier across
