Suddenly, away on our left, I saw a faint flickering blue flame. The driver saw it at the same moment; he at once checked the horses, and, jumping to the ground, disappeared into the darkness. I did not know what to do, the less as the howling of the wolves grew closer; but while I wondered the driver suddenly appeared again, and without a word took his seat, and we resumed our journey. I think I must have fallen asleep and kept dreaming of the incident, for it seemed to be repeated endlessly, and now looking back, it is like a sort of awful nightmare. Once the flame appeared so near the road, that even in the darkness around us I could watch the driver’s motions. He went rapidly to where the blue flame arose⁠—it must have been very faint, for it did not seem to illumine the place around it at all⁠—and gathering a few stones, formed them into some device. Once there appeared a strange optical effect: when he stood between me and the flame he did not obstruct it, for I could see its ghostly flicker all the same. This startled me, but as the effect was only momentary, I took it that my eyes deceived me straining through the darkness. Then for a time there were no blue flames, and we sped onwards through the gloom, with the howling of the wolves around us, as though they were following in a moving circle.
