and brought from a distant locality ; it resembled the mixture of peroxide of iron and quartz: 
found at the outcrop of metallic lodes and known as ‘ Gossan’ in Cornwall. The method of 
smelting the iron in small furnaces is similar to that used in other parts of India, but 
the bellows employed are worked with the foot, a peculiarity only found in the south-western 
dependencies of Bengal and in Orissa. An account of the process with figures by my brother, 
Mr. H. F. Blanford, will be found in Dr. Percy’s Metallurgy of Iron and Steel, p. 261. 
The arenaceous ironstones of the Damuda group would, doubtless, yield a large supply 
of ore. 
Denkinal and Hindole. —These require scarcely any notice. So far as is known, they 
consist of metamorphic rocks, except the western extremity of the first named State which 
comprised the eastern end of the Talchir basin. The metamorphic rocks are of the usual 
descriptions. 
Atgaeh. —The northern and western parts of this State consist of metamorphic rocks. 
Along the Mahanaddi from near Katak to the boundary of the state within three or four miles 
of the village of Tigeria, there is a belt four or five miles broad of the same “ Katak” sand¬ 
stones as are seen south of the Mahanaddi in the Puri district, being in fact a portion of the 
same basin. The rocks are precisely similar—coarse sandstones and conglomerates with 
one or more bands of white clay. 
Banki. —West of the sandstone area in the Puri district there is a broad expanse of 
alluvium running for a considerable distance to the southward from the Mahanaddi; west of 
this again metamorphic rocks occur. There is a fine semicircle of detached hills running from 
Bankigarh to the village of Bydesar. The hills are partly of garnetiferous gneiss, partly 
of compact hornblendic gneiss. Banki Peak is of very quartzose gneiss. The strike varies 
in a peculiar manner, being very irregular, but with a general tendency in all the hills to dip 
towards the centre of the semicircle. South of the hills is a large undulating plain partly 
covered with laterite.

Notes on a new Coal-field in the south-eastern part of the Hydeabad (Deccan) 
Teeeitoey, by William King, B. A., Deputy Superintendent, Geological Survey of 
India, 
In the regular course of my work I have found a further small and hitherto unknown 
outlier of coal-bearing rocks, some thirty miles south-east of the Kamaram or Pangady 
Yagu field already described in these records.* 
The present field is situated between about 17° 30'—17° 40’ north latitude, and 
80° 18'—80° 25' east longitude, near the villages of Rumpaid, Yellindallapad.f Hooserakapully, 
and Ragabonagoodium, in the eastern part of the Knndyconda talook. Its southern 
extremity is about four or five miles east of the large village of Siugareny, and it may be 
as well to give this name to the field. 
It is a narrow irregular patch of the ‘ plant-bearing series’ of rocks, about eleven miles 
long and from one to two miles in width, giving an area of about nineteen square miles, though 
at the same time the coal measures are only supposably about eight square miles in extent.

t Yellindallapad is nearest to the outcrop of coal seam; but it is deserted at present (March 1872), Kollapoor 
and Cheedamulla (Sodamilla), a couple of miles to the east, are larger villages.
