For some months the man and woman maintained their residence in the cave, uninterrupted by any visits from other human inhabitants of the forest. Daily Longhead went forth in search of food, which he brought to the cave and they shared it together. Sometimes there was plenty, but often their meals were scanty, as the only weapons then known were stones and clubs. Broken Tooth aided to some extent, by searching a piece of low moist ground not far from the cave for such roots and tubers as were palatable, and altogether, they managed to sustain life as well as before their union, but the woman never ventured far from the platform for fear that by some accident their precious fire should go out.

Every night the fire blazed merrily upon the platform, fed with dry branches and large sticks, which it was the task of the woman to procure during the day. Frequently they saw wild animals in the forest at night or heard their growls as they prowled in the surrounding thickets, but never after their experience with the tiger the first night of their fire, did one venture within the charmed circle of the light made by the flames.

Sometimes when it rained or the weather was cold, and sufficient food remained over from the night before, Longhead lingered about the cave and platform all day, enjoying the warmth and comfort of the fire, and on these occasions the couple talked much of the benefits of their new acquisition.

One day Broken Tooth said: "What shall we say if some of the people wander this way and find us? What shall we tell them about how we came in possession of this new comfort?" Then they talked about this long and earnestly. They had no desire to benefit their fellows by sharing with them their accidental discovery, for man was yet a purely selfish animal, and there was no organized society of any kind; but they both recognized the fact that when others became acquainted with its benefits, they would soon acquire the fire, by force if necessary, and that their own lives would stand for nothing, should they resist. They felt sure that the matter could not long be concealed from other members of their group, for the first hunter who should wander to that part of the forest would smell the smoke and would investigate. It was finally concluded that, as they did not themselves know how the fire had originated in the heap of logs and brush, they would say Longhead himself had produced it in a mysterious manner, which they dare not reveal for fear it might be taken from them.

That they might not be observed in the mornings kindling the fire with punk and tinder, and their secret be thus exposed, it was agreed that all the punk should be kept in the cave, the fires lighted there, and only brought out on the platform after the sticks were ablaze.

Every night two pieces of punk were ignited and laid carefully up on a small natural projecting shelf in the cave. They used two pieces, fearing that by some accident one might become extinguished. The fact is, this very thing did happen once. The lighted punk had been laid back against the rear wall of the platform when they went to bed, but a violent storm had come on in the night and the rain had been driven in so that the punk was wet and the spark gone in the morning. Their precious fire was only saved by Broken Tooth finding a tiny spark on the under side of a log which the water had not happened to reach. They had been greatly alarmed, and so two pieces had been thereafter lighted and both taken into the cave to avoid such another mishap.

This peaceful enjoyment of their new-found happiness and companionship had continued for some months, when one evening a small animal which they were about to tear to pieces for their evening meal, fell into a large bed of burning coals on the platform. Longhead was about to recover it when Broken Tooth, whose sense of smell may have been more acute, said: "Wait a minute; what is that delicious smell?"

Up to this time they had still continued to eat their food raw, and there had been nothing to suggest to the mind of either that it would be better if exposed to heat. Now they continued for some minutes to inhale the new and agreeable odor, but it had the effect to make Longhead ravenously hungry, and he soon drew the animal from the coals with a long stick. When he began to tear it the hot carcass burned his fingers, which alarmed him at first, but the demands of his appetite must be satisfied, and, tearing it in pieces, he divided with the woman. At first they both tasted gingerly and were a little afraid of the unaccustomed heat, but before either had finished the first morsel their pleasure was evident. They devoured the whole of the animal, and declared it the finest eating they had ever experienced. Two or three other small animals lay beside the fire and they decided to repeat the course. Both had observed that the portions of the first animal which had been most exposed to the heat had been made tender and more appetizing, and, on the suggestion of Broken Tooth, a long slender stick was thrust through an animal, which was by this means held over the hottest part of the bed of coals by Longhead, who turned it from time to time, that all parts might be thoroughly cooked. This was so much better than the first that their appetites returned with renewed vigor, and when the second animal had been eaten, they again repeated the courses until all the food on hand had been devoured. They both declared that roasted meat was far superior to raw, and agreed that this should be the method of preparing meat for the future.

One day when Broken Tooth returned from the swamp with some wild carrots and other roots, she thrust one into a pile of hot ashes and burning coals, merely as an experiment. She left it there while she collected some fuel and replenished the fire, and when she drew it out and tasted it she was pleased to find that roots also were much improved by cooking. When Longhead returned in the evening he was treated to a surprise—supper of two courses, broiled wood-rat and roasted carrot.

Everything to be used for food was thereafter submitted to the cooking test, and, whenever broiling or roasting in the ashes seemed to improve the taste of any article of food, this was adopted.

Longhead and Broken Tooth now found themselves really caring for each other and each sought to do things to please the other. As far as they were concerned, the old selfishness was now gone. Their close companionship around the fire alone during the evenings; its cheerful light and gay sparkle, its warmth and comfort tended to promote conversation and they found themselves talking more than they had ever before in their lives. They even coined a few words to express their new experiences and feelings. Longhead would relate in detail the hunting adventures of the day and Broken Tooth would recount her own experiences in search of roots and eggs.

Both thoroughly enjoyed their new life at the fire-cave; indeed, it seemed to them they had never really lived before.

Nearly every day Longhead would go into the forest in search of small animals for food. In his absence Broken Tooth first collected sufficient fuel to keep the fire alive for another twenty-four hours, then she would visit the low ground for roots and tubers, eggs and nuts, for since they had been experimenting with roasting, they had discovered that a number of roots which had been rejected as bitter and unpalatable, when raw, were much improved by roasting, and these had been added to the bill of fare. Broken Tooth had found nesting places of the waterfowl which frequented the swamp. Her first experiment in roasting eggs had been a partial failure. She placed a couple of eggs in the hot ashes, noticing at the time that the shell of one was cracked; soon there was an explosion and the egg with the sound shell was destroyed. Thereafter she made a small hole in each for the escape of the steam and all went well. Her worst trouble with eggs was the want of a receptacle for transporting them to the fire-cave, for she wore not even an apron.

When evening began to draw near, Broken Tooth found herself looking often into the forest and wishing for Longhead's return. She sometimes feared a savage beast might have killed him. This was a new feeling for her. In the former life she had never cared for any one or cared particularly to see others. One evening when the man finally appeared, she ran into the forest to meet him and put her arms around his neck. Longhead looked at her in some surprise and then returned the caress, and they walked arm in arm to the platform. That evening they both talked a great deal, and finally Broken Tooth said: "I wonder what has come over both of us. Even when together for a short time in the old days, we spoke but seldom. I wonder if it is the fire."

It was indeed the fire, with its warmth and cheer, so different from the old days when each had shivered in the fork of a tree or had spent the night in a dark and noisome cavern. Neither understood the nature of the change which was being wrought in them, but if it was not yet real marriage, it was at least the germ which in the long succeeding ages has developed into real marriage.

One morning a cold rain was falling and Longhead sat long before the blazing fire, loth to leave the comfort he found there for the chilly and dripping forest. He drew a long slender stick from the fire and began to observe its glowing end. As the ashes accumulated and hid the red coal, he blew them away. After a few minutes, the fire on the stick went out and the man, picking up a piece of stone, began idly and without purpose to scrape away the black or charred portion of the end. When he reached the unburned wood, he found it very hard and as he continued to scrape, he finally brought the stick to a very sharp point. He felt this and thought it might be very good for killing small animals, so when he finally started out for his day's search for food, he took it with him. It was fortunate he did so, for late in the afternoon as he was turning toward home, after an unsuccessful hunt, a pack of wild dogs attacked him. So close were they upon him before he was aware, that the leader sprang at him to pull him down just before he reached a tree in which he was about to take refuge. In defense, he thrust the sharpened stick at the beast with all his might. It passed clear through the body of the dog, which fell dead and was quickly devoured by its fellows, while the man scrambled to safety. When Longhead climbed down, after the dogs had dispersed, he secured the sharpened stick, and it was with a new feeling of safety he moved through the forest, spear in hand; for a spear had been invented. A few days later he even ventured to attack a wild dog he found separated from the pack; a thing he never would have done when armed with only a club or stone. He killed the animal and carried it in triumph to the fire-cave, for it was the first time, to his knowledge, a man, ever, single-handed, had killed so large an animal of a ferocious kind. Its roasted flesh supplied the man and woman food for several days.

One day, when kindling a fire on the platform, the woman was too indolent to remove some small boulders from the spot where she desired to make the fire, so she piled the fuel over them and was surprised to find that the fire kindled more readily and burned better on account of the fuel being raised from the ground, and thereafter, three or four stones were used to support the sticks. One morning, after the fire had burned for some time and the stones were red hot, a smart shower came up. The fire was too far under the slope of the shelving rock to be directly affected, but as it continued to rain for some time, a small pool accumulated on top of the rock, which finally worked its way through the bed of leaves that had dammed its progress and, all at once, it poured over the face of the rock in a small column and fell directly upon one of the red-hot stones in the fire-place. The stone was a large nodule of flint; there was an immediate explosion, a dense cloud of steam and ashes arose, and the alarmed owners of the cave rushed for safety to its depths. When all was quiet they emerged to find that one of the stones which supported the sticks had disappeared. Instead of the stone, however, there were numerous sharp flakes of flint scattered about, which Longhead first discovered when he cut his foot by stepping on one.

With much curiosity, the man examined the flake which had injured him, then picking up the carcass of a small animal lying near, he found that he could cut it with the flake. He now carefully gathered up all the flakes he could find and carried them into the cave. When he returned from his day's hunt in the evening, he brought with him a long, slender, dry stick which he rubbed and polished with a flake until perfectly smooth; then, with some fibrous roots, he bound the longest and sharpest of his flakes at the end of the pole, and the next day carried this with him to the forest instead of the fire-hardened wooden spear. Later, he discovered that narrow strips of rawhide were better than roots for tying on a flake, and, after many years of progress, the long tendons of large animals were substituted as still better for the purpose.

Longhead and his new deadly weapon had numerous encounters with small animals, in each of which he found his new spear superior to anything he had yet tried, and this gave him still greater confidence in himself. He no longer sneaked through the forest half bent to the ground and fearing nearly every animal he might meet, but went with head erect and a more fearless step.

A few days later, while pursuing some half-grown wild pigs, and when they were about to plunge into a den in the rocks, he threw his spear at the last one, in disappointment. To his surprise, it passed clear through the animal, killing it at once. He carried the pig to the cave and that night sat long before the fire in deep thought. Finally, he selected a long and thin fragment of flint, rather broader than those he had used for the spear, wrapped some small roots about it at one end to protect his hand, and he had a knife—the first one in the world. The next morning he tied a strip of bark around his waist to support the knife, and when he returned in the evening he brought with him several dry and slender sticks shorter than his spear and proceeded to bind a sharp splinter of flint to each. Thereafter, he always carried one of these short ones in addition to his long spear, and thus a javelin was invented. He practiced throwing this at every animal he saw, and, indeed, at other objects, and soon became quite expert in its use. He found, too, that it was now much easier to keep the larder well supplied.

In his wanderings, Longhead one day approached quite near the locality in which he had formerly resided with the group, and where he had received the terrible beating which had made him an exile. He gnashed his teeth when he thought of the man who had vented his jealous rage upon him and was wondering in his mind how he could obtain revenge. At that instant he turned around a point of rocks and found himself face to face with the giant himself. The fellow was all of a head taller and at least fifty pounds heavier than Longhead; his strength was immense and his temper ferocious. By reason of his size and fierce temper, as well as the surly grunts he generally used instead of words, he was known among the people of the group as the Bear. He was a veritable tyrant and most of the others were practically his slaves. When Bear saw a man or woman with food he wanted, he reached for it with a roar, and it was at once given up or its owner was beaten nearly to death. He had a large number of the women so terrified that they did not dare to associate with the other men; these he kept near himself and compelled them to supply him with food. Longhead had once persuaded one of these women to accompany him on a trip in search of food. They were absent several days, and on his return, Bear had given him the beating. Bear knew him at once, and with a howl of rage and uplifted club, rushed upon him. Longhead was terribly frightened, and for a moment forgot all about his spear, but in a second he recalled the fate of the pig and other animals and, with all his strength, he threw his javelin at the hairy breast of the advancing enemy, now but a pace or two distant. It went nearly through his body and, with a yell of pain, the giant threw up his hands and fell to the ground. He tried to pull the weapon from his body, and failing in this, writhed in agony for a few moments and then lay perfectly still. He was dead, and Longhead looked with wonder and awe at his victim.

Fighting was not uncommon among the men of that period, but being without dangerous weapons, the fights had generally resulted in one or both the combatants being more or less seriously but not dangerously injured, and this was the first time Longhead had ever seen one human being killed by another. Deaths he had, of course, known, but they had been from disease, accident or wild animals.

He now heard some of the people approaching, and drawing his javelin from the corpse, he concealed himself near-by to observe the effect when they should discover the body. There were three of the party, and at first they thought Bear asleep and shouted to arouse him, but when they discovered the blood and the hole in his breast, they perceived that he was dead.

Longhead in hiding heard no expressions of sorrow or regret, for, to tell the truth, Bear was no favorite with the group. His immense size and irascible disposition had made him a bully, and there were few who had not been beaten by him at some time; therefore, the remarks overheard by the man in hiding were rather to the effect that the finders were well enough pleased, but they expressed great wonder at the wound and could not conceive what animal had caused it, especially as there were no marks of teeth or claws or any other wounds on the body. They picked up the corpse, however, and started with it toward the late habitation of the giant.

Longhead left his retreat and proceeded thoughtfully toward the fire-cave. His revenge was gratified and he felt happy on that account, but the wonderful character of his weapon was beginning to dawn upon his dull intelligence, and he no longer feared man or beast. He dimly recognized that with such a weapon a small man was the equal of a giant.
