"You see," continued Grenville, "I can make an imitation cannon, from one of my bamboo lengths, and leave it here to fool them. They may be led to think it the only gun we've had, and search no farther for our ordnance. The smoke is likely to lift, I think, which is why I'm at work before breakfast." He did not complete the arrangements of his ruse before they broke their fast, however, since the making of an imitation cannon required at least an hour. The last of their meat, save a little intended for fishing-bait, was consumed with the insignificant remnants of their fruit supply, and Grenville took time to catch one silvery fish from the ledge in front of the cavern, as well as to gather a lot of the mussels, for luncheon and dinner, before he returned to the terrace. Already the breeze was failing. There were streaks of highly acceptable air interspersed with the billows of smoke. Not without a certain impatience to have this business concluded before the veiling fumes should leave the terrace entirely exposed to the penetrative sight of the Dyaks, Grenville hastened the construction of his imitation gun, to be left by the heap of stones. That a more convincing appearance of over-use might assist in creating the desired impression, he selected one of the bamboo sections already badly split. This he readily blackened by burning a handful of powder, loosely, inside its muzzle. With a rude vent cut and similarly treated, the affair was ready to be bound with discarded creepers, then lodged in the rocks above the genuine bit of artillery still ready for grim engagements. All that remained of the powder in his cave was carefully moved to the passage, there to be most cautiously deposited, away from all possible fire, along with his coils of fuse. Somewhat to his disappointment, the northerly breeze seemed once more freshening as the morning hours advanced. He had hoped not only for a lifting of the smoke, but likewise to find the Dyaks' boat once more encircling the headland. Beyond transferring his water supply from the jugs to a number of bamboo buckets, which permitted no waste by percolation, he had nothing further to employ his time as the day wore slowly on. The heat in the meantime was intolerable. The fish was roasted in an "oven" he fashioned of the heat-retaining tufa. The mussels were likewise "steamed" in their own exuding juices, occupying the large and basin-like sea-shell for the purpose. It was not until nearly four in the afternoon that the wind definitely veered. Grenville had noted the coming alteration that would clear the hill of fumes in time to make all essential preparations for the Dyak watchfulness. His furnace of fire was duly banked, to continue a smoldering glow among the ashes without producing smoke. Elaine had retired within the passage, and the entrance door to this secret hiding-place was adjusted against the rock.
