Elaine was standing in her shelter door when at length he came once more to his place by the top of the trail. She, too, had discovered the absence of the native vessel. "I think another one came in the night," she said, when Sidney explained his belief that the boat was in hiding behind the farther walls. "I am sure I heard another voice." Grenville recalled the shout that had followed the chanting and felt that this accounted for Elaine's conviction that more of the Dyaks had arrived. "We have not been actually seen as yet," he assured her. "Our flag of distress is not a positive sign of anyone's presence on the island. We shall soon determine by their movements whether these chaps intend to be friendly or not." "Would they hide if they meant to be friendly?" "It isn't a friendly sign---- You see, I'm still of opinion the island's wail is a sound they rather dread. Have you noticed it's rapidly failing?" "I've been ever so glad it seems so short and growing fainter." "Yes," he drawled. "I'm afraid it will soon cease altogether, when our friends may buck up their courage and--show us their state of mind." "What can we do in the meantime?" "Sit tight and watch for developments." But all that day there was never so much as a sound or a sign of the crew they had seen arrive. At one time, just before noon, Grenville fancied some movement occurred in the rocks that crowned the second hill. But he detected no further indication that someone might have scaled the cliff to spy on himself and Elaine. He had never in his island rambles discovered a place by which that hill could be surmounted. That easy access might be obtained on the seaward side he readily understood. He fretted under the long suspense--the uncertainty brooding over the island. He much preferred that the visitors exhibit a downright hostile intent than to feel that beneath the sinister calm of thicket and jungle might lurk insidious death. He felt that Elaine and himself would lack for nothing, except fresh meat, for at least a couple of days, yet he knew that even their fruit supply was wholly inadequate for a siege, should the new arrivals make up their minds to starve them on the terrace. Rather than weakly submit to any such abominable tactics, he was fully determined to bring about an attack. But how was an open question. When once again the night drew on the man was impatient and weary. He had taken no rest after all his long previous day of toil, yet to sleep and invite disaster up the trail was quite impossible. "We shall have to divide the night," said Elaine, with her customary practical courage. "We have simply got to be sensible to preserve our strength in case we have to fight."
