He remembered how, ten months or possibly ten years ago, he had encountered a box turtle in a forest clearing, and had shouted at it: "_They went thataway!_" The turtle's rigidly comic face, fixed by nature in a caricature of startled disapproval, had seemed to point up some truth or other. Brian had hunkered down on the moss and laughed uproariously--until he observed that some of the laughter was weeping. Today had been rather good. He had killed a deer on the Palisades, and with bow and arrow, thus saving a bullet. Not that he needed to practice such economy. He might live, he supposed, another decade or so at the most. His rifles were in good condition and his hoarded ammunition would easily outlast him. So would the stock of canned and dried food stuffed away in his living quarters. But there was satisfaction in primitive effort and no compulsion to analyze the why of it. The stored food was more important than the ammunition. A time would come soon enough when he no longer had strength for hunting. He would lose the inclination for trips to cross the river. He would yield to such laziness or timidity for days, then weeks. Some time, when it became months or years, he might find himself too feeble to risk climbing the cliff wall into the forest. He would have the good sense then, he hoped, to destroy the canoe, thus making of his weakness a necessity. * * * * * There were books. There was the Hall of Music on the next floor above the water, probably safe from its lessening encroachment. To secure fresh water, he need only keep track of the tides, for the Hudson had cleaned itself and now rolled down sweet from the lonely, uncorrupted hills. His decline could be comfortable. He had provided for it and planned it. Yet gazing now across the sleepy water, seeing a broad-winged hawk circle in freedom above the forest, Brian was aware of the old thought moving in him: "If I could hear voices--just once, if I could hear human voices...." The Museum of Human History, with the Hall of Music on what Brian thought of as the second floor, should also outlast his requirements. In the flooded lower floor and basement, the work of slow destruction must be going on. Here and there, the unhurried waters could find their way to steel and make rust of it, for the waterproofing of the concrete was nearly a hundred years old. But it ought to be good for another century or two. Nowadays the ocean was mild. There were moderate tides, winds no longer destructive. For the last six years, there had been no more of the heavy storms out of the south. In the same period, Brian had noted a rise in the water level of a mere nine inches. The window-sill, his port, was six inches above high-tide mark now. Perhaps Earth was settling into a new, amiable mood. The climate had become delightful, about like what Brian remembered from a visit to southern Virginia in his childhood.
