According to his story, he was “... out one very dark night stopping up fox-earths. While I was so engaged I saw a very bright blue light pass close to my face and was very much startled as I saw it going away from me ... I put it down as some insect.” After the mysterious light reappeared a few nights later, the gamekeeper prudently began carrying his gun and eventually he managed a shot at the light. To his amazement he brought down “a poor old half-starved barn owl, _Tyto alba_, whose body continued to glow for some hours after death.”[VI-1] _The Luminous Owls of Norfolk_ Some ten years later, on the night of February 3, 1907, another Englishman and his son while taking a walk observed a similar luminous phenomenon. Apparently about a quarter of a mile away, it moved horizontally over a course several hundred yards in length, reversed direction, then rose into the air to the height of forty feet or more. “It then descended and again went through the same evolutions many times. The light was slightly reddish in the centre, and resembled a carriage lamp for which we at first mistook it. We watched it for twenty minutes and were quite at a loss to ascertain its cause.
