This is known as the pot ore. Black band is more frequent but has been worked less than the pot ore. Black band usually appears at from eight inches to eighteen inches thick, and yields about forty per cent iron. Pot ore generally yields about fortyfive or fifty per cent iron. Pot ore is so uncertain in its amount in one place, that it is seldom worked with profit, and with little dependence.
Black band lies in strata and is worked with dependence and success.
The coal now being mined is of a superior quality, and all obtained from drifts. South of Moxahala, if the coal is mined it must be by shafts, one or two of which are being sunk at this time, 1882. There is one small shipping bank at North Ferrara. The health of the township is extremely good, and upon account of the undulations of its surface, they never suffer from miasmatic influence. The hills are indeed picturesque, and are to the student an open book of nature, from which the geological formations may be studied without even the aid of a book or teacher.
