There were now five members in this family of the period, One-Ear, Red-Spot, Ab, Bark and Beech-Leaf, the two last named being Ab's younger brother and little more than baby sister. The names given them had come in the same accidental way as had the name of Ab. The brother, when very small, had imitated in babyish way the barking of some wolfish creature outside which had haunted the cave's vicinity at night time, and so the name of Bark, bestowed accidentally by Ab himself, had become the youngster's title for life. As to Beech-Leaf, she had gained her name in another way. She was a fat and joyous little specimen of a cave baby and not much addicted to lying as dormant as babies sometimes do. The bearskin upon which her mother laid her had not infrequently proven too limited an area for her exploits and she would roll from it into the great bed of beech leaves upon which it was placed, and become fairly lost in the brown mass. So often had this hilarious young lady to be disinterred from the beech leaf bed, that the name given her came naturally, through association of ideas. Between the birth of Ab and that of his younger brother an interval of five years had taken place, the birth of the sister occurring three or four years later. So it came that Ab, in the absence of his father and mother, was distinctly the head of the family, admonitory to his brother, with ideas as to the physical discipline requisite on occasion, and, in a rude way, fond of and protective toward the baby sister.
