When at length night came on and the darkness made the firelight more brilliant, the man piled a large number of sticks on the fire to show how the forest was lighted up; but finally both became weary of the sport, and then he told her of the cave near-by--just large enough for two--and invited her to share it with him for the night. She consented, and as they were about to start, the man, without any thought of the effect, gathered up four or five of the sticks with live coals at the end and placed them together. These he waved in the air to amuse the woman with the flying sparks, as they passed along, she still screaming at each successive sparkle, until suddenly a bright flame shot up and, by accident, like many other valuable discoveries, a torch was invented. By its light they easily made their way to the rocky platform in front of the cave sheltered by the overhanging rock, and when Longhead cast down the torch Broken Tooth placed the ends of the burning sticks together as she had seen him do, and again the flame shot up. The new experience was too delightful to be given up, and, at the woman's suggestion, they gathered large armfuls of dry branches and some heavy logs which lay scattered about near the platform, which they piled up and from time to time added to the fire. The night was cool, but as they sat back against the wall of rock under the sloping cliff to watch the blaze and flying sparks, a pleasant warmth, new to their experience, pervaded their bodies, and they gave themselves up to the luxury of the sensation. The fire roared and blazed merrily, Broken Tooth shouted in glee, and Longhead began to think, in a slow ponderous way, that this new agent in his life might do much for his comfort if it could be perpetuated, but his mental power was too limited to suggest any method for this.
