(3 pieces.) 
The foregoing coals are all from the great Indian 
coal-beanng seines of rocks which belongs to the 
same horizon (geologically) as the lowest Permian or 
uppermost coal measures of Europe (approximately) 
The following coals are of different geologicai 
age 
204. Coal, from near Cherra Poonji, Khasia Hills, 
East Bengal. 
Phis occurs at the base of the Nummulitic series, 
G. S. I. From Colonel Bivar, Deputy Commissioner, 
Khasia Hills. 
205. Coal, from Thangjinath, Khasia Hills. TLis 
bed is lower in the geologicai series, and 
probably belongs to the latest portion of the 
cretaceous series. 
206. Coal, from Lakadong, Jynteah Hills. Tertiary. 
Tools. 
207. A set of the tools used by the native Colliers 
is also exhibited. They consist of a crowbar 
hammers, chisels, wedges, a vessel made of 
part of a bamboo, for holding oil and a crude 
lamp cut out of stone, in which this oil is 
burned. There is little or no fire-damp or 
explosive gases from the Indian coals, and the 
mines are all worked with open lights. Sent 
by T. Hmdhaugh, Esq., Equitable Coal Com- 
pany. 
208. Another series of tools, such as are used in the 
native manufacture of iron is shown. They 
eonsist of an instrument used for breaking 
the ore a pair of large tongs, and a pair 
of smaller tongs. An instrument for breaking 
the smeited iron a pair of bellows such as 
are used with the smelting fumaces, an 
Instrument used in digging the iron-ore and 
a mamooty or common shovel. Sent by the 
Madras Committee. J 
Salt. 
Of the salt produced and used in India, there are 
two great vaneties. One, salt produced by evapora- 
tion of the water of bnne-springs, salt-lakes, and of 
the sea, and so artificially crystallised. The other 
native rock salt which is worked in several places, 
but niost largely in the Salt Range, Punjab, and 
across the nver Indus, in the Kohat district. There 
is also a large arnoimt of salt imported from Great 
Britain, and used chiefly in the neighbourhood of 
the port towns. 
1 he general section of the Salt Range is illustrated 
by a series of specimens of the successive beds in 
the immediate neighbourhood of the very extensive 
mines near Pind Hadun Khan, now called “The 
“ Mayo Mines.” 
In descending order, these are
