A tin mine here employed a windmill for pumping Mining Journal 1846-02-14: Vol 16 Iss 547

On the summit of Kit Hill, tin ore was also found in small veins of a very pure quality; here a windmill was erected a few years since, which, for a time, effectually drained the shaft, until a sudden storm wrecked the frail machine, and with it the hopes of the adventurers.

KITT HILL.- This mine has been resumed. There are in the sett many lodes, chiefly of tin, which is very rich in quality. It has been repeatedly wrought, and as frequently abandoned for want of funds to prosecute it to a sufficient depth. A Windmill was erected to draw the tinstuff and water, the only one which has been applied to this purpose. The indications warrant a vigorous prosecution of the mine.
