What I saw—or fancied I saw—was a disturbing suggestion of undulant motion far to the south; a suggestion which made me conclude that a very large horde must be pouring out of the city along the level Ipswich road. The distance was great and I could distinguish nothing in detail; but I did not at all like the look of that moving column. It undulated too much, and glistened too brightly in the rays of the now westering moon. There was a suggestion of sound, too, though the wind was blowing the other way—a suggestion of bestial scraping and bellowing even worse than the muttering of the parties I had lately overheard.
