The doorway, for obvious reasons, was narrow and there was a huge rock, long ago rolled inside with much travail, which could on occasion be utilized in blocking the narrow passage. Barely room to squeeze by this obstruction existed at the doorway. The sneaking but dangerous hyena had a keen scent and was full of curiosity. The monster bear of the time was ever hungry and the great cave tiger, though rarer, was, as has been shown, a haunting dread. Great attention was paid to doorways in those days, not from an artistic point of view exactly, but from reasons cogent enough in the estimation of the cave men. But the cave was warm and safe and the sharp eyes of its inhabitants, accustomed to the semi-darkness, found slight difficulty in discerning objects in the gloom. Very content with their habitation were all the family and Red-Spot particularly, as a chatelaine should, felt much pride in her surroundings. It may be added that the family of One-Ear was a happy one. His life with Red-Spot was the sequence of what might be termed a fortunate marriage. It is true that standards vary with times, and that the demeanor of the couple toward each other was occasionally not what would be counted the index of domestic felicity in this more artificial and deceptive age. It was never fully determined whether One-Ear or Red-Spot could throw a stone ax with the greater accuracy, although certainly he could hurl one with greater force than could his wife. But the deftness of each in eluding such dangerous missiles was about the same, and no great harm had at any time resulted from the effects of momentary ebullitions of anger, followed by action on the part of either. There had not been at any time a scandal in the family. The pair were faithful to each other. Society was somewhat scattered in those days, and the cave twain, anywhere, were generally as steadfast as the lion and the lioness. It was centuries later, too, before the cave men's posterity became degenerate enough or prosperous enough, or safe enough, to be polygamous, and, so far as the area of the Thames valley or even the entire "Paris basin," as it is called, was concerned, monogamy held its own very fairly, from the shell-beds of the earliest kitchen-middens to the time of the bronze ax and the dawn of what we now call civilization.
