PART 2.] Mallet: On the mineral resources of Rdmri, Cheduha, Sj-c. 
Limestone is very plentiful in Ramri. One of tlie most important localities 
is just noi’t-h of the Yanthek creek, about two miles 
Limestone. north of the village of the same name. The rock 
there is yellowish-white or occasionally reddish. It is rather brittle, and gener¬ 
ally has a tolerably smooth fracture. Some parts have a fine gT’anular stnicturc. 
It includes strings and seams of calcspar, which weather out prominently from 
the mass of the rock, but it is free from chert and from interbedded layers of 
other rock. The bedding is generally obscure, and masses 20 feet thick occur in 
which none is apparent. In places, however, the rock has a slight tendency to 
flagginess. The dip and strike seem to be very incorustant. The supply is 
unlimited. I mj’self saw the stone to be continuous over an area of many acres, 
forming rocky hillocks 20 to 40 feet high, and the villagers with me said that it 
extends over an area four kos in circuit. The limestone is situated close to 
a tidal creek which joins the Yanthek creek within 200 yards, so that there is great 
facility for exportation. 
The analysis of a carefully chosen average sample, made up of pieces from 
several of the small native quarries, yielded—

The manufacture of lime is carried on in the neighbourhood, but not on any 
large scale. The rock is quarried with crowbars and hammers, having been pre¬ 
viously heated by brushwood fires : gunpowder is not used. The kilns in which 
it is burned are circular, about 8 feet in diameter at the top and rather more at the 
bottom, with a depth of about 10 feet. They are dug out on a steep clay-bank, 
and have one orifice in front at the bottom about 18 inches diameter. There is 
a low clay wall round the top. 
The lower part of the kiln is filled wdth logs of wood and the upper with 
broken stone in pieces up to some inches diameter. After some days, when the 
fire has burned out, the top portion of the stone, which is only partially burned, 
is removed separately, and the lime then withdrawn and slaked. Salt water 
from the creek is used for this purpose, as being the nearest at hand, but it is 
by no means calculated to improve the lime. The half-burned stone is added to 
the next firing. The slaked lime is sold at the kilns at the rate of twenty rupees 
per hundred matis (maunds). 
Limestone of a very similar character to that at Yanthek also occurs in 
large quantity near Tsinbok. It is a yellowish-white rock looking like indurated 
chalk. Besides veins of calcspar it contains an occasional nodule of chert, 
which I have not observed in the rock at Yanthek. There are at least two out¬ 
crops to the south-west of the village, at one of which the limestone forms a 
hillock 30 feet high. From this alone a very large supply could be obtained, and 
it is within less than a mile and a half of a tidal creek. The composition of the 
stone is very similar to that of the Yaxithek rock.
