He surveyed what should be the direction of the land. A light showed there and vanished, then came on again and vanished. A minute later it showed and disappeared, then came on again twice. It was very far away. Davis said in a different tone, "We can change course now, Deirdre. You know the new one." The _Esperance's_ bowsprit forsook the star at which it had been aiming. It swung to another. Davis moved about, adjusting the sheets alone. On the new heading the yacht heeled over a little more and the water rushing past her hull had a different sound. The sky seemed larger and more remote than it ever appears from a city. The yacht's wake streamed behind her in a trail of bluish brightness. Even the moon was strange. It had the cold enormousness of something very near and menacing. It looked as close as when seen through a telescope of moderate power. The _Esperance_ seemed very lonely on the immense waste of waters. Next morning, of course, the sense of loneliness was gone. There was neither land nor any ship in sight, but gulls fluttered and squawked overhead, and the waves seemed to leap and gambol in the sunshine. Just before the foremast a metal plate in the decking had been lifted up, and a new, stubby, extensible mast rose almost as high as the crosstrees. A tiny basket-like object rotated monotonously at its upper end. It was a radar-bowl, and somehow it was not unusual, except in the manner in which it was mounted. Yet, such a collapsible radar mast was reasonable on a sailing yacht with many lines aloft that could be fouled. Anyhow, the radar was concerned with human affairs, and so it was company. The housekeeping work on the boat was in progress. Doug and Jug scrubbed the deck. The other crew-cuts gave signs of industry from time to time, appearing and vanishing. Davis smoked tranquilly at the wheel. Terry felt useless, as well as puzzled. "Can I do anything?" he asked awkwardly. "You're your own boss," said Davis. "Then I might as well see what can be done about that submarine noisemaker." "If you feel like it," said Davis, "fine!" But he did not urge. Terry waited a moment. There was a sort of contagion of purposefulness in this eccentric small group on the _Esperance_. They had something they were trying to do, and it seemed important to them. But Terry was an outsider and would remain one until he became active in their joint effort.
