MANGANESE DEPOSITS OF INDIA : DESCRIPTIVE. [ PaRT IV : 
another place, close at hand, is a small cave in limonitic rock containing 
a great abundance of the tiny magbetite octahedra. In the workings 
this bedded limonitic rock is seen to be passing into laterite, processes 
and patches of which project irregularly into the limonitic rock. In 
places this laterite contains abundance of fine-grained blue pyrolusite. 
Judging from the stacked ore, the pyrolusite forms in the limonitic rock 
also, by direct replacement, without the formation of laterite. The 
whole of the surface of the hills just here shows lateri tic rock, often 
containing abundance of angular and rounded fragments of the limonitic 
rock with some of phyllitic rock. This resembles the lateritic con- 
glomerate of Ramandrug, and seems to have been formed by the 
superficial cementation of the loose pieces of the rock of this place by 
oxides of iron. The amount of ore in this deposit did not seem to be 
large. 
Other deposits. 
I was also able to examine some specimens of Goa ores in the 
possession of Mr. Ghose. The Vaotim (or Vaomti) deposit is situated 
about 1 i miles E. N. E. of Fanuswadi, and is held by the West Coast 
Manganese Syndicate. Mr. Ghose 's specimens

from here are mixtures of laterite, yellow 
ochre, and pyrolusite, with occasional psilomelane. One of them shows 
a patch of decomposed quartzite. The Kandiapsir deposit, held by 
Captains Lacerda and Rollo and some of their friends, lies some 2k miles 
N. E. of Ponda in the Ponda division of the

ronda district. The ore is said to be mainly 
psilomelane. A beautiful specimen from here showed compact 
psilomelane arranged in bands round a flat cavity lined with a soft 
black coat of minute felt-like crystals. From this deposit, said to be 
one of the largest in Goa, about 2,000 tons of ore have been despatched 
to Mormugao. The ore is sent by cart to the coast and then by boat 
to Mormugao. 
I have also been able to examine some samples brought by 
Mr. H. D. Coggan from the Embarbacem
