"Plenty fine and strong," he said, holding it up with pride. "De one end hang on a rock or de stump of a bush, and de oder for de leg."
"I believe you have thought of the very thing," exclaimed Tyler in delight. "With a sling like that we could sit all day long and never tire. We will wait till the heat gets too great for us and then we will retire. Get hold of your share of the ammunition and food while I take mine. Now, how is the bonfire going."
He almost laughed as he spoke, but a moment later his face wore a serious expression, for though but little time had elapsed since the man below had so daringly set fire to the bushes, yet the hot sun overhead had dried the wood till it was like tinder, and scarcely had it felt the flame than it flared in all directions. Then, as if there had been a train of powder laid beneath, the conflagration spread almost as fast as a man could run, for all the world like the veldt fires in Africa, and, sweeping along the straggling line, quickly reached the base of the rock. And here, with abundant material before it upon which to vent its power, the flame spread to either hand, and thence came marching up the steep rock, fanned by a gentle breeze from the river. Like an army in straggling array it swept the rock before it, and halting here, falling back there for an instant as it met with a bush of more succulent wood, which defied its power on account of its moisture, it came staggering upwards, ever upwards, roaring as it went, and sending forth dense masses of blinding, hot smoke. Very quickly the bushes which grew just below the retreat in which Tyler and the Chinaman had taken up their station were singed and frizzled by the heat, while they themselves were driven backwards. A minute and they were racing up the steep slope, madly eager to escape from the fire and get to a safe distance.
"Here is a clear spot with only one strong bush growing," gasped Tyler, as they reached the summit, halting at a spot which was clear and bare of growth save for a solitary bush. "Out with your knife, Li, and hack it down. That's the way. Leave enough to fasten our slings to."
Desperately and in all haste did the Chinaman carry out the order, for a hot wave fanned his cheek, and a cloud of smoke and sparks told him that he had no time for delay. In a few minutes, therefore, he had lopped off the greater part of the bush, leaving the base of it alone. And to this, thrusting their slings over the gnarled and twisted root till they were close to the ground, did the two suspend their weight, hoping that it would not fail them and send them tumbling to the ground beneath.
Meanwhile the pirates below had watched with eager eyes as the fire advanced, and set up a babel of discordant shouts as they saw the two figures above forced to retreat. With loud and discordant yells they followed their course to the summit of the rock, and then, as they watched and noted the methodical way in which the bush was lopped off and the slings attached, a doubt, and fear that after all they were to be beaten in this, their final attempt, assailed them. With a shout of indignation and annoyance they raced through the jungle to the back of the rock, and, arrived there, stared up at Tyler and Li Sung, who swung easily at their posts, their weight supported by the slings, while they prevented their bodies from swaying too much by grasping the edge of the rock with their fingers. Instantly a fusillade was opened in their direction, the bullets for the most part falling short, or pattering harmlessly against the rock. A few, however, struck with resounding thuds, warning Tyler that a blow from one, while it would not penetrate perhaps, would be likely to stun the one who was hit should it happen to come in contact with his head.
"We must put a stop to that game," he said suddenly. "They seem to have forgotten that we, too, are armed, and we must remind them. Just place your hand on my shoulder to steady me, and I will give them a shot. That's the way. Now I can lift my rifle without swinging round and running the risk of toppling over."
That the precaution was very necessary both could see, for, suspended as they were, with one leg thrust through the sling till the latter gripped them about the thigh, the greater part of their weight was above the point of support, and had it not been for the grip which each had obtained on the edge of the rock they would have run the danger of capsizing and slipping from the sling. It was a matter of some difficulty, therefore, to make use of a weapon, but with Li to help him Tyler contrived to get his rifle to his shoulder. Then he calmly selected the nearest of the pirates, and just as the latter was about to fire at him, he pressed the trigger and sent his bullet into the man.
"See how they scamper away," he cried with a laugh, as the Malays took to their heels. "We shall not be troubled again by their firing, I fancy, and very soon darkness will hide them from our view. I suppose that it is not possible to clamber down this side, for it has suddenly struck me that the rock will be very hot on the farther slope."
