coal seam

There was Milan Hruška, a fiery miner from the North Bohemian coal mines.

Life can be tough in West Virginia, especially for the hardworking souls of coal country.

It was little better than coal dust, and would not carry a ball fifty paces to kill or wound.

Of late, however, it has acquired a far greater interest through the discovery of coal underneath its surface.

And one of the seraphims flew to me, and in his hand was a live coal, which he had taken with the tongs off the altar.

An explosion took place in the Blackheath coal mines, Virginia; by which of the twenty-three workmen only one escaped death.

But its use as such is to dispose of any such idea as that there is a natural price of coal or of anything else.
