A strange-looking animal was running across the open glade toward the forest. It looked something like a human being, but was entirely naked. Its body, except on the palms of the hands and soles of the feet, was covered with reddish-brown hair, but on the head it was nearly black and long and matted; while on the rest of the body it was short and curled—nearly fur, in fact. Its arms were long, reaching below the knees, and the great toes, as it ran, stood nearly at right angles to the others.

The animal carried no weapon of any kind, if we except a club or staff broken from a dry branch, which it seemed to use in maintaining an upright position as it hurried toward a large tree with pendent branches which stood at the edge of the forest.

Just as the creature reached the outer branches, which extended nearly to the ground, a storm, which had been rapidly approaching, burst with great violence. There was a loud clap of thunder, a bolt of lightning tore the tree to splinters, and the animal fell to the ground, stunned by the shock. It lay unconscious for some time, and the thunder shower had passed, leaving the sun shining brightly, when it raised its head and sat up. At first it slowly rubbed its body and head, and then, reaching full consciousness, its attention was attracted by a roaring and crackling sound a short distance away.

The lightning had prostrated the tree and had set fire to a mass of brush and logs lying at its roots. The beast sprang to its feet in astonishment and alarm.

The animal was one of our primitive ancestors, and he now saw fire for the first time.

As his body, chilled by the recent rain, began to feel the warmth, he first drew near, but as the heat increased, he was compelled to withdraw to a greater distance. He gazed as if fascinated, however, at the curious sight for a long time.

When it began to grow dark, he was surprised to see that the forest for some distance around, remained nearly as light as day.

His feeble intellect, however, soon wearied of the new sensation, and he withdrew to an overhanging rock near-by. He knew of a small cave at its base with a narrow entrance, and of this he at once took possession, rolling against the opening some masses of stone lying near and piling in others after he had entered, until he had secured the opening against any dangerous animal. He gave little further thought to the phenomena of the fire, for man had not yet reached a development in intellect which permitted a consecutive train of thought for any considerable length of time. He slept soundly, but when he crawled from his refuge in the morning, the smoke still rising from the pile of logs and brush attracted his attention and recalled to his mind what had occurred the evening before. He approached the fire, which had nearly consumed its supply of fuel, but was smouldering still in a large decayed log and the ends of several poles which lay partly in a bed of glowing coals.

A HUGE TIGER WHICH WAS SLOWLY CREEPING UP BEHIND HIM.
