And in his heart he buried his fears as unworthy delusions, as the imaginings of a brain still hurt. The occasional black looks of one or another of the people, or perchance some sullen, muttered word, he set down as the crude manners of a primitive and barbarous race. How little, despite all his skill and wit, he could foresee the truth! To Beatrice he spoke no word of his occasional uneasiness, nor yet to the old man. Yet one of the very first matters he attended to was the overhauling of the revolvers, which had been rescued out of the melee of the battle and been given to the patriarch, who had kept them with a kind of religious devotion. Stern put in half a day cleaning and oiling the weapons. He found there still remained a hundred and six cartridges in his bandolier and the girl's. These he now looked upon as his most precious treasure. He divided them equally with Beatrice, and bade her never go out unless she had her weapon securely belted on. Their life at home was simple in the extreme. Beatrice had the inner room of the hut for her own. Stern and the patriarch occupied the outer one. And there, often far into the hours of the sleeping-time, when Beatrice was resting within, he and the old man talked of the wonders of the past, of the outer world, of old traditions, of the abyss, and a thousand fascinating speculations. Particularly did the old man seek to understand some notions of the lost machine on which the strangers had come from the outer world; but, though Stern tried most patiently to make him grasp the principle of the mechanism, he failed. This talk, however, set Stern thinking very seriously about the biplane; and he asked a score of questions relative to the qualities of the native oil, to currents in the sea, locations, depths, and so on. All that he could learn he noted mentally with the precision of the trained engineer. With accurate scientific observation he at once began to pile up information about the people and the village, the sea, the abyss--everything, in fact, that he could possibly learn. He felt that everything depended on a sound understanding of the topography and nature of the incredible community where he and the girl now found themselves--perhaps for a life stay. Beatrice and he were clad now like the Folk; wore their hair twisted in similar fashion and fastened with heavy pins or spikes of gold, cleverly graven; were shod with sandals like theirs, made of the skin of a shark-like fish; and carried torches everywhere they went--torches of dried weed, close-packed in a metal basket and impregnated with oil. This oil particularly interested Stern. Its peculiar blue flame struck him as singular in the extreme. It had, moreover, the property of burning a very long time without being replenished. A wick immersed in it was never consumed or even charred, though the heat produced was intense.
