She remained beside him at their fire till long past the midnight hour. Indeed, she had made no move to retire when at length the weird, unwelcome disturbance made by the tide had begun its uncanny chorus. Perhaps she had waited for the conclusion of this added feature of the night's long ritual of nerve-attacking events, for she seemed to be considerably cheered when its final wail had died upon the air. "It seems to me that doesn't continue quite as long as it did at first," she said to Grenville, as she rose at last to go alone to her cavern.... "I think you ought to rest. I wish you would." "I will," said Sidney. "Good-night." But, for some time after she had gone, he sat there wondering if those abominable but protective cries, that haunted the island's solitude, were actually on the wane. "God help us if they are!" he said, to himself, but he went to bed and slept. CHAPTER XX A GIRDLE OF GOLD Elaine had not yet appeared on the scene when Grenville went down to the jungle. The morning hour was still decidedly early, but plans and impatience to be up and at work had prodded the man from his rest. The lassitude that should have followed his night of excitement had not yet laid its weight upon him. Apparently nothing had come to the jungle scene where the tiger had met his end. The great form lay there, torn and rigid, but no sign of the cat could be discovered. Grenville passed his trophy, presently, to examine the space beyond. The spot where the bomb had exploded was a gaping hole in the earth. This was not the place where Grenville had placed the deadly tube, which he knew must therefore have been moved--doubtless when the fuse was pulled and broken by the creature taking refuge in the tree. All about the spot where the kill had been the shrubbery was shredded. The boar's remains had been blown away when the gap was made in the sod. The trail, Grenville saw, must be repaired or a new one must be made about the place. He returned to the tiger, and was suddenly elated to behold the metal collar, half-hidden by the fur about his neck. He had quite forgotten this bauble, thus singularly employed, and, kneeling down to inspect it closely, not only found it was massive gold and set with costly jewels, but also discovered he must break or force a heavy link to take it from the creature. It was not until he had brought two sharp-edged rocks to his needs that the collar was finally freed. Its weight and worth then amazed him. The band was fully two inches in width, with the edges curved up and turned under, in a simple and hammer-marked finish. It was all hand-wrought, each blow that the smith had struck with his tool being faintly recorded in the metal. The jewels--three sapphires, three rubies, and one diamond--were simply and solidly set with bands that barely clasped their bases. The rubies only were cabochon cut, the other stones gleaming with facets.
