It looked exactly like a lantern carried by a man.

It was very indistinct, but wavered about, always floating about a foot or two from the surface, sometimes standing still as though he was looking for something on the ground, and sometimes moving very quickly.

It was a will-o'-the-wisp--a phosphorescent exhalation.
"It was a foul pestilential place, there is no doubt.

The mist was all about us by midnight, and smelt very heavy and cold.
