la addition to the above, we have received many specimens of various kinds for assay, 
or examination, among which some of the more important were of iron ores from various 
localities. 
The results of a recent search in the neighbourhood of Ilazaribagh yielded to Dr. Coates 
and Mr. Donaldson a considerable variety of ores, the principal of which. were from 
the Karanpura coal-field and its vicinity, examined sometime since, but not published from 
want of a correct map. The following numbers show the percentage of metallic iron con¬ 
tained in each. Of course this is the full percentage, and this proportion would not be 
obtained in manufacture. As the details of these researches will be given elsewhere, we only 
give the localities and percentages here :—

A specimen, found loose, to the north-west of Haz/ivibagh yielded 68'7 per cent. With 
the exception of this, which is magnetite, and of the BelhargadM specimen, all the others 
are varieties of clay-ironstone. 
From tiro Wun District, East Berar, the Deputy Commissioner forwarded several ores 
for assay. Some of these were fine rich brown haematite traversed by crystalline veins of 
tlie pure mineral; these varieties were assayed, yielding, respectively, 60'4, 56'3, and 440 per 
cent, of iron. If with these we take the percentage of the pure limonite, we will have—

or 
an 
average yield of 50 per cent, of 
metallic iron. There are distinct traces of phosphorus. These specimens wei'e from veins of 
segregation traversing the beds; but some of the beds themselves are rich and useful ores 
yielding 48'0 and 45'8 per cent, of iron. 
In the immediate neighbourhood of those ores heaps of old slag are scattered over the 
ground. These slags, the result generally of very crude and inefficient methods of smelting, 
often contain a very large dose of iron, and it was interesting to examine them. Two speci¬ 
mens were assayed; and one yielded 38’0, the other 34'8 per cent, of iron—an amount which 
would be ample to pay for re-smelting these slags in conjunction with other ores. 
In the Yetiak hills, which occur west of the village of that name, near the river 
Painganga, in the southern part of the WtJn District, East Berar. Mr. Hughes and Mr. Feddelt, 
during their recent examination of the country, traced over an extent of some five to six 
miles iu length two thick beds of conglomerate (nowhere less than nine feet) containing a 
large proportion of rolled lumps of a very rich hcematite. This on assay yielded no less 
than G8'5 per cent, of iron with a trace of phosphorus—no manganese. 
All these are rich and valuable ores of iron and occur in largo abundance. The noted hill 
from which much of the ore smelted by the natives in North-Eastern Chanda is derived, the 
Lohara hill, near Bissanpuri, is one mass of iron-ore of a couple of miles in leno-th. A 
specimen brought by Mr. W. T. Blanford proved to be nearly pure specular iron with a 
proportion of magnetic iron, and yielded to assay 70 per cent, of metallic iron!
