They were large black pools a man could spend an evening just gazing into.

He had entered a black pool of ground, a place where no light penetrated.

There was a huge black pool, and standing all around were a few hundred soldiers.

I looked down at the still, black pool six or eight inches below the top of the pit.

The black pool might have been a hundred miles distant, for all the good it did him.

To the right was the long pool, still, intensely black, its surface like a mirror.

At the bottom was a black pool she recognized but did not understand.

Now she saw a straight path leading like a pier into a deep black pool.

The blood spread in a black, pristine pool at his feet.

Oh, he could distinguish two black pools, but not what they held.
