coal pit

This town has somewhat the color of a coal-pit, or of a black-smith's shop.

We record this month a signal act of heroism which took place a few years ago in a coal-pit near Dalkeith.

Could fresh air not be forced down by the power of the steam-engine, which is at every coal-pit?

The air of the coal-pit is so charged with carbon as to prevent the collier from distinguishing his neighbour when at work.

We might as well look for the moon in a coal-pit, as for stays or white linen in the City of Mud.
