Such were the father and mother of Ab, and such was the boy himself. His surroundings have not been indicated with all the definiteness desirable, because of the lack of certain data, but, in a general way, the degree of his birth, the manner of his rearing and the natural aspects of his estate have been described. That the young man had a promising future could not admit of doubt. He was the first-born of an important family of a great race and his inheritance had no boundaries. Just where the possessions of the Ab family began or where they terminated no bird nor beast nor human being could tell. The estates of the family extended from the Mediterranean to the Arctic Ocean and there were no dividing lines. Of course, something depended upon the existence or non-existence of a stronger cave family somewhere else, but that mattered not. And the babe grew into a sturdy youth, just as grow the boys of today, and had his friendships and adventures. He did not attend the public schools--the school system was what might reasonably be termed inefficient in his time--nor did he attend a private school, for the private schools were weak, as well, but he did attend the great school of Nature from the moment he opened his eyes in the morning until he closed them at night. Of his schoolboy days and his friendships and his various affairs, this is the immediate story. The father and mother of Ab as has, it is hoped, been made apparent, were strong people, intelligent up to the grade of the time and worthy of regard in many ways. The two could fairly hold their own, not only against the wild beasts, but against any other cave pair, should the emergency arise. They had names, of course. The name of Ab's father was One-Ear, the sequence of an incident occurring when he was very young, an accidental and too intimate acquaintance with a species of wildcat which infested the region and from which the babe had been rescued none too soon. The name of Ab's mother was Red-Spot, and she had been so called because of a not unsightly but conspicuous birthmark appearing on her left shoulder. As to ancestry, Ab's father could distinctly remember his own grandfather as the old gentleman had appeared just previous to his consumption by a monstrous bear, and Red-Spot had some vague remembrance of her own grandmother.
