"Come, girl, _en marche!_" cried the man cheerily, as he adjusted Beta's knapsack so that the platted cord should not chafe her shoulders, then swung his own across his back. And with a buoyant sense of conquest, yet a regret at leaving the little camp which, though crude and rough, had yet been a home to them for a week, they turned their faces to the rising sun and set out on the journey into the unexplored. Much altered were they now from those days at Hope Villa, when they had been able to restore most of the necessities and even some of the refinements of civilization. Now the girl's hair hung in two thick braids down over her worn tiger-skin, each braid as big as a strong man's wrist, for she lacked any means to do it up; she had not so much as a comb, nor could Stern, without a knife, fashion one for her. Their sandals hung in tatters. Stern had tried to repair them with strips of squirrel-skin clumsily hacked out with the sharp clam-shell, but the result was crude. Long were his hair and beard, untrimmed now, unkempt and red. Clad in his ragged fur garment, bare legged and bare armed, with the grass-cloth sack slung over his sinewy shoulder and the heavy stone-ax in his hand, he looked the very image of prehistoric man--as she, too, seemed the woman of that distant age. But though their outward guise was that of savages far cruder than the North American Indian was when Columbus first beheld him, yet in their brains lay all the splendid inheritance of a world-civilization. And as the fire-materials in Stern's sack contained, in germ, all the mechanic arts, so their joint intelligence presaged everything that yet might be. They traveled at an easy pace, like voyagers who foresee many hard days of journeying and who are cautious not at first to drain their strength. Five hours they walked, with now and then a pause. Stern calculated they had made twelve miles or more before they camped beside a stream that flowing thinly from the wood, sank into the sand and was lost before it reached the sea. Here they ate and rested till the sun began to pass its meridian, when once more they started on their pilgrimage. That night, after a day wherein they had met no other sign of life than gulls and crows ravaging the mussel-beds, they slept on piles of sun-dried kelp which they heaped into some crevices under an overhanging brow of low cliffs on a rocky point. And dawn found them again, traveling steadily eastward, battle-axes swinging, hopes high, in perfect comradeship and faith. Toward what must have been about ten o'clock of that morning they reached the mouth of a river, something like half a mile wide where it joined the sea. By following this up a mile or so they reached a narrow point; but even here, burdened as they were, swimming was out of the question.
