Hitherto, the active life of the island, the shade of trees, hut or cave, the power of unrestricted movement and the possession of water in any desired quant.i.ty, robbed the tropical heat of the day of its chief terrors. Now all was changed. Instead of working amidst grateful foliage, they were bound to the brown rock, which soon would glow with radiated energy and give off scorching gusts like unto the opening of a furnace-door.

This he had foreseen all along. The tarpaulin would yield them some degree of uneasy protection, and they both were in perfect physical condition. But--if Iris were wounded! If the extra strain brought fever in its wake! That way he saw nothing but blank despair, to be ended, for her, by delirium and merciful death, for him by a Berserk rush among the Dyaks, and one last mad fight against overwhelming numbers.

Then the girl's voice reached him, self-reliant, almost cheerful--

"You will be glad to hear that the cut has stopped bleeding. It is only a scratch."

So a kindly Providence had spared them yet a little while. The cloud pa.s.sed from his mind, the gathering mist from his eyes. In that instant he thought he detected a slight rustling among the trees where the cliff shelved up from the house. Standing as he was on the edge of the rock, this was a point he could not guard against.

When her welcome a.s.surance recalled his scattered senses, he stepped back to speak to her, and in the same instant a couple of bullets crashed against the rock overhead. Iris had unwittingly saved him from a serious, perhaps fatal, wound.

He sprang to the extreme right of the ledge and boldly looked into the trees beneath. Two Dyaks were there, belated wanderers cut off from the main body. They dived headlong into the undergrowth for safety, but one of them was too late. The Lee-Metford reached him, and its reverberating concussion, tossed back and forth by the echoing rocks, drowned his parting scream.

In the plenitude of restored vigor the sailor waited for no counter demonstration. He turned and crouchingly approached the southern end of his parapet. Through his screen of gra.s.s he could discern the long black hair and yellow face of a man who lay on the sand and twisted his head around the base of the further cliff. The distance, oft measured, was ninety yards, the target practically a six-inch bull's-eye. Jenks took careful aim, fired, and a whiff of sand flew up.

Perhaps he had used too fine a sight and ploughed a furrow beneath the Dyak's ear. He only heard a faint yell, but the enterprising head vanished and there were no more volunteers for that particular service.

He was still peering at the place when a cry of unmitigated anguish came from Iris--

"Oh, come quick! Our water! The casks have burst!"

It was not until Jenks had torn the tarpaulin from off their stores, and he was wildly striving with both hands to scoop up some precious drops collected in the small hollows of the ledge, that he realized the full magnitude of the disaster which had befallen them.

During the first rapid exchange of fire, before the enemy vacated the cliff, several bullets had pierced the tarpaulin. By a stroke of exceeding bad fortune two of them had struck each of the water-barrels and started the staves. The contents quietly ebbed away beneath the broad sheet, and flowing inwards by reason of the sharp slope of the ledge, percolated through the fault. Iris and he, notwithstanding their frenzied efforts, were not able to save more than a pint of gritty discolored fluid. The rest, infinitely more valuable to them than all the diamonds of De Beers, was now oozing through the natural channel cut by centuries of storm, dripping upon the headless skeleton in the cave, soaking down to the very heart of their buried treasure.

Jenks was so paralyzed by this catastrophe that Iris became alarmed. As yet she did not grasp its awful significance. That he, her hero, so brave, so confident in the face of many dangers, should betray such sense of irredeemable loss, frightened her much more than the incident itself.

Her lips whitened. Her words become incoherent.

"Tell me," she whispered. "I can bear anything but silence. Tell me, I implore you. Is it so bad?"

The sight of her distress sobered him. He ground his teeth together as a man does who submits to a painful operation and resolves not to flinch beneath the knife.

"It is very bad," he said; "not quite the end, but near it."

"The end," she bravely answered, "is death! We are living and uninjured. You must fight on. If the Lord wills it we shall not die."

He looked in her blue eyes and saw there the light of Heaven.

"G.o.d bless you, dear girl," he murmured brokenly. "You would cheer any man through the Valley of the Shadow, were he Christian or Faint-heart."

Her glance did not droop before his. In such moments heart speaks to heart without concealment.

"We still have a little water," she cried. "Fortunately we are not thirsty. You have not forgotten our supply of champagne and brandy?"

There was a species of mad humor in the suggestion. Oh for another miracle that should change the wine into water!

He could only fall in with her unreflective mood and leave the dreadful truth to its own evil time. In their little nook the power of the sun had not yet made itself felt. By ordinary computation it was about nine o'clock. Long before noon they would be grilling. Throughout the next few hours they must suffer the torture of Dives with one meager pint of water to share between them. Of course the wine and spirit must be shunned like a pestilence. To touch either under such conditions would be courting heat, apoplexy, and death. And next day!

He tightened his jaws before he answered--

"We will console ourselves with a bottle of champagne for dinner.

Meanwhile, I hear our friends shouting to those left on this side of the island. I must take an active interest in the conversation."

He grasped a rifle and lay down on the ledge, already gratefully warm.

There was a good deal of sustained shouting going on. Jenks thought he recognized the chief's voice, giving instructions to those who had come from Smugglers' Cove and were now standing on the beach near the quarry.

"I wonder if he is hungry," he thought. "If so, I will interfere with the commissariat."

Iris peeped forth at him.

"Mr. Jenks!"

"Yes," without turning his head. He knew it was an ordinary question.

"May I come too?"

"What! expose yourself on the ledge!"

"Yes, even that. I am so tired of sitting here alone."

"Well, there is no danger at present. But they might chance to see you, and you remember what I--"

"Yes, I remember quite well. If that is all--" There was a rustle of garments. "I am very mannish in appearance. If you promise not to look at me I will join you."

"I promise."

Iris stepped forth. She was flushed a little, and, to cover her confusion, may be, she picked up a Lee-Metford.

"Now there are two guns," she said, as she stood near him.

He could see through the tail of his eye that a slight but elegantly proportioned young gentleman of the sea-faring profession had suddenly appeared from nowhere. He was glad she had taken this course. It might better the position were the Dyaks to see her thus.

"The moment I tell you, you must fall flat," he warned her. "No ceremony about it. Just flop!"

"I don't know anything better calculated to make one flop than a bullet," she laughed. Not yet did the tragedy of the broken kegs appeal to her.

"Yes, but it achieves its purpose in two ways. I want you to adopt the precautionary method."

"Trust me for that. Good gracious!"

The sailor's rifle went off with an unexpected bang that froze the exclamation on her lips. Three Dyaks were attempting to run the gauntlet to their beleaguered comrades. They carried a jar and two wicker baskets. He with the jar fell and broke it. The others doubled back like hares, and the first man dragged himself after them. Jenks did not fire again.

Iris watched the wounded wretch crawling along the ground. Her eyes grew moist, and she paled somewhat. When he vanished she looked into the valley and at the opposing ledge; three men lay dead within twenty yards of her. Two others dangled from the rocks. It took her some time to control her quavering utterance sufficiently to say--

"I hope I may not have to use a gun. I know it cannot be helped, but if I were to kill a human being I do not think I would ever rest again."

"In that case I have indeed murdered sleep today," was the unfeeling reply.
