Richard stood where he was for over an hour, until the fog began to thin.

It was then that a strong wind picked up and the fog began to part.

The fog began to lift, and we could feel the heat.

The fog began to thin and I found myself able to advance.

The fog began to close in, and I had to climb.

Indeed they thought not of him, for soon the fog begin to melt away, and all was clear again.

But the fog was beginning to have a permanent look.

Outside the clear sky vanished as a light fog began to form along the street.

He got back to the camp at three o'clock as the fog was just beginning to close down.

Eventually the fog begins to clear a little, and you find yourself back in the hold again.
