The crawling objects he had seen from above had vanished beyond the solid wall he had built to shut out the tiger. All the way down to this barrier he made his way, Elaine meanwhile watching from the cliff. There were dark, irregular blotches here and there along the rocks, and on these he scraped a hiding film of dust. How much of the contents of the gun had been expended uselessly against the wall could not be determined in the dark. He felt assured a heavy toll had been collected on the trail, if not in killed, at least in wounded and, doubtless, disabled men.
The cord arranged to sound his alarm had been broken in the charge. He found the ends, repaired the damage, crept further along to scan the silent and deserted clearing, then promptly returned to secure a basket, and boldly went down to gather extra fruit.
"I wish I knew where to get some meat," he told Elaine, as he came with his plunder to the terrace. "I don't know when I shall have another hour so absolutely safe."
But beyond removing his ladder and bridge, he performed no more labor that night. It was not yet late. Elaine was too excited to retire. She sat with him, nervously listening to all the far sounds of the jungle, as he kindled their fire to a blaze.
"I wonder how long we can keep it up—go on as we are going now," she reflected aloud at last. "Mustn't they get us in the end?"
"Well—not till we've made it a fair exchange, at least."
"There must be a dozen of them about us, six or more to our one."
"There were, perhaps, an hour ago, but hardly so many now. One shot himself, down in the jungle, gunning for me, while the cannon—— But your intuition was accurate—a second boatload did arrive to join the first." He added a brief recital of what he had seen and what had taken place at the rotted barque, sparing the details which, he felt, would more alarm than assure her, respecting "Buli" and the drama played at the clearing.
"Two boatloads!" she repeated. "What reason could they possibly have for coming at last to this island? They couldn't have known we were here—at least not the first who came."
"No," said Grenville, slowly, reflecting that the time for his revelation was, perhaps, a trifle overdue, "they came, I believe, to secure the treasure in the cave."
