fog bank

For a moment the fog-bank rose and a circle of ocean lay before them.

My face was westward now, and I kept my eye upon the fog-bank creeping stealthily after us.

But of a sudden a group of similar machines, flying like wild geese, appeared out of the fog-bank.

Dixon stood nearer to his companion, and they stood side by side, looking into the fog-bank, which was now upon them.
