There still remains upon the east coast of England the great 
Cleveland region, and upon its west coa^t the Cumberland or 
red hematite region. The latter is now yielding about 1,400,- 
000 tons of ore per annum, taken from beds of'irregular shape 
and formation, in or adjacent to the limestone. There are cer¬ 
tainly no signs of exhaustion as yet apparent in this wonder¬ 
ful district, but all analogy leads us to doubt the permanency 
of these irregular beds, formed in pockets in the rocks, without 
any regular walls to indicate their continuity. Besides the 
extremely good quality of this ore and the value of the iron 
which it produces, will always restrict its use to those better 
purposes for which a high price is paid, and naturally with¬ 
draws those mines from any competition in the supply of the 
great mass of iron required by the world for ordinary pur¬ 
poses. Not so, however, with the Cleveland region, where 
the ores exist in beds of from eight feet to fifteen feet in thick¬ 
ness, in the lias or oolitic formation, extending over a tract of 
country forty miles in length and fifteen miles in width. This
