I laughed, for the danger from Indians was long since past, but said readily enough that I would do as she wished, being, in fact, glad enough of a gallop in the moonlight, with the prospect of meeting Mary.  So in a few minutes I was in the saddle and riding toward Jamestown.  The night was very bright with the moon, and there was a great mist rising from the marshy lands, and such strangely pale and luminous developments in the distances of the meadows, marshalling and advancing and retreating, like companies of spectres, and lingering as if for consultation on the borders of the woods, with floating draperies caught in the boughs thereof, that one might have considered danger from others than Indians.  And, indeed, I often caught the note of an owl, and once one flitted past my face and my horse shied at the evil bird, which is thought by the ignorant to be but a feathered cat and of ill omen, and indeed is considered by many who are wise to have presaged ill oftentimes, as in the cases of the deaths of the emperors Valentinian and Commodus.  Be that as it may, I, having a pistol with me, shot at the bird, and, though I was as good a shot as any thereabouts, missed, and away it flew, with a great hoot as of laughter, which I am ready to swear I heard multiplied in a trice, as if the bird were joined by a whole company, and my horse shied again and would have bolted had I not held him tightly.  Now, this which I am about to relate I am ready to swear did truly happen, though it may well be doubted.  I had come within a short distance of Jamestown when I reached two houses of a small size, not far apart, not much removed from the fashion of the negro cabins, but inhabited by English folk.  In the one dwelt a man who had been transported for a grievous crime, whether justly or not I cannot say, but his visage was such as to condemn him, and he was often in his cups and had spent many days in the stocks, and had made frequent acquaintance with the whipping-post, and with him dwelt his wife, an old dame with a tongue which had once earned her the ducking-stool in England.  As I passed the house I saw over the door a great bunch of dill and vervain and white thorn, which is held to keep away witches from the threshold if gathered upon a May day.  And I knew well the reason, for not many rods distant was the hut where dwelt one Margery Key, an ancient woman, who had been verily tied crosswise and thrown in a pond for witchcraft and been weighed against the church Bible, and had her body searched for witch-marks and the thatch of her house burned.  I know not why she had not come to the stake withal, but instead she had fled to Virginia, where, witches being not so common, were treated with more leniency.  It may have been that she had escaped the usual fate of those of her kind by being considered by some a white witch, and one who worked good instead of ill if approached rightly, though many considered that they who approached a white witch for the purpose of profiting by her advice
