The fringe of palms was in turn ringed in by a round mile of flat, sandy country. They followed it south and brushing through a farther rim of tropical vegetation came out on a pearl-gray virgin beach where Ardita kicked of her brown golf shoes--she seemed to have permanently abandoned stockings--and went wading. Then they sauntered back to the yacht, where the indefatigable Babe had luncheon ready for them. He had posted a lookout on the high cliff to the north to watch the sea on both sides, though he doubted if the entrance to the cliff was generally known--he had never even seen a map on which the island was marked.
