Most of the people in the group to which he belonged had short round heads, such as scientists call brachiocephalic, but this man was dolichocephalous, or longheaded, and this peculiarity had given him the name of Longhead among this group at the few gatherings of these people, which happened occasionally, more by accident than design, for they had no social organization whatever. They had no laws; no leaders; no permanent habitations and wore no clothing. They slept in nests built in the branches of trees at night, or sought shelter in any chance caves of the region through which they roved. This had no defined boundaries and they remained in the locality only because they found food fairly plentiful. As yet, there was not even family organization, for it was many ages after this time before it dawned upon man anywhere that the male animal played any part in the propagation of species. To the ordinary and usual phenomena of nature our primitive forefathers never gave a thought or question, but accepted them without speculation as to their cause or fear as to their continuance, so long as regularity obtained. The rising and setting of the sun were to him perfectly natural events of daily occurrence from his childhood, and had so continued during the recollection of the oldest members of the group, and it was only when eclipses occurred, breaking this orderly continuity, that he felt at all alarmed. It was natural for the moon to shed her soft light when not obscured by clouds, and even its waxing and waning occasioned no alarm, for this, likewise, had continued "since the fathers fell asleep." There was nothing strange about the gentle dew descending by night or rain falling from the clouds; these he had observed from his earliest youth; but when the loud thunders reverberated through the hills, and the forked lightnings flashed athwart the sky, frequently rending the giant trees of the forest or bringing sudden death to a comrade, this mysterious and dangerous display of an unknown power, was, to him, alarming, and he early attributed these and all other infrequent or unaccountable phenomena to supernatural beings with whom his fancy peopled the hills and forests, the rivers and the sky.
