IRON. 
521 
celebrated iron-founderies of Carron in Scotland are 
principally established. 
Iron-stone is found in abundance in Derbyshire, 
at various depths from the surface of the earth. 
The most valuable beds of this mineral which have 
yet been discovered, are in Morley Park, near 
Heage; at Winger worth, Chesterfield, and Staveley. 
In Cumberland argillaceous iron-stone is very com- 
monly met with either on or near the surface in most 
parts of the county. In the parish of Egremont, at a 
place called Crowgorth, there is a mine of this ore. 
It is described as lying in the earth at the depth 
of twelve fathoms ; and the thickness of the band 
of ore, which is hard solid iron-stone, is between 
twenty-four and twenty-five feet. It was never con- 
sidered of much consequence till the year 1/84 and 
1785, when it was more generally opened ; and the 
demand for it has since been so great, from different 
founderies, that in 1 79 1 and 179 2 the annual ex- 
portation was more than 20,000 tons. Masses and 
beds of this mineral are likewise found in Glamorgan, 
Monmouth, Staffordshire, Shropshire, and in differ- 
ent parts of Scotland. 
There is hardly a country in the world without 
its mines of iron, and most of them possess a con- 
siderable number. Of these we shall just notice a 
few, and refer our readers for a more particular enu- 
meration to Brongniart’s Traite Elementaire de Mi- 
ner alogie. 
The principal mines of Sweden are those in the 
environs of Phillipstadt, that of Taberg in Smoland,
