Extract

Of all the “troubles” that afflict the Ironstone miner, few are more perplexing than those known as “wants.” It sometimes happens that in the course of the working a “face” is being carried forward into the ironstone seam, when the miner finds that he has taken out what is apparently the last piece of “stone,” and looks with astonishment at “the blaise where the stone should be.”
