Deep Down, a Tale of the Cornish Mines (Paperback)

Thus down, down, he goes, sinking his shaft and driving his levels on-that is, always following the lode ad infinitum. Of course he must stop before reaching the other side of the world At the present time Botallack has progressed in that direction to a depth of 245 fathoms. To those who find a difficulty in realising what depth that really is, we would observe that it is equal to more than three and a half times the height of St. Paul's Cathedral in London, nearly four times the height of St. Rollox chimney in Glasgow, and considerably more than twice the height, from the plain, of Arthur's Seat, near Edinburgh.
