Iris strove to be severe, but there was a touch of anxiety in her tone that instantly made the sailor apologetic. He told her about the ledge, and explained his half-formed notion that here they might secure a safe retreat in case of further attack--a refuge from which they might defy a.s.sault during many days. It was, he said, absolutely impossible to wait until the morning. He must at once satisfy himself whether the project was impracticable or worthy of further investigation.

So the girl only enjoined him to be careful, and he vigorously renewed the climb. At last, some twenty-five feet from the ground, an accidental parting in the branches enabled him to get a good look at the ledge. One glance set his heart beating joyously. It was at least fifteen feet in length; it shelved back until its depth was lost in the blackness of the shadows, and the floor must be either nearly level or sloping slightly inwards to the line of the fault.

The place was a perfect eagle's nest. A chamois could not reach it from any direction; it became accessible to man only by means of a ladder or a balloon.

More excited by this discovery than he cared for Iris to know, he endeavored to appear unconcerned when he regained the ground.

"Well," she said, "tell me all about it."

He described the nature of the cavity as well as he understood it at the moment, and emphasized his previous explanation of its virtues.

Here they might reasonably hope to make a successful stand against the Dyaks.

"Then you feel sure that those awful creatures will come back?" she said slowly.

"Only too sure, unfortunately."

"How remorseless poor humanity is when the veneer is stripped off! Why cannot they leave us in peace? I suppose they now cherish a blood feud against us. Perhaps, if I had not been here, they would not have injured you. Somehow I seem to be bound up with your misfortunes."

"I would not have it otherwise were it in my power," he answered. For an instant he left unchallenged the girl's a.s.sumption that she was in any way responsible for the disasters which had broken up his career.

He looked into her eyes and almost forgot himself. Then the sense of fair dealing that dominates every true gentleman rose within him and gripped his wavering emotions with ruthless force. Was this a time to play upon the high-strung sensibilities of this youthful daughter of the G.o.ds, to seek to win from her a confession of love that a few brief days or weeks might prove to be only a spasmodic, but momentarily all-powerful, grat.i.tude for the protection he had given her?

And he spoke aloud, striving to laugh, lest his words should falter--

"You can console yourself with the thought, Miss Deane, that your presence on the island will in no way affect my fate at the hands of the Dyaks. Had they caught me unprepared today my head would now be covered with a solution of the special varnish they carry on every foreign expedition."

"Varnish?" she exclaimed.

"Yes, as a preservative, you understand."

"And yet these men are human beings!"

"For purposes of cla.s.sification, yes. Keeping to strict fact, it was lucky for me that you raised the alarm, and gave me a chance to discount the odds of mere numbers. So, you see, you really did me a good turn."

"What can be done now to save our lives? Anything will be better than to await another attack."

"The first thing to do is to try to get some sleep before daylight. How did you know I was not in the Castle?"

"I cannot tell you. I awoke and knew you were not near me. If I wake in the night I can always tell whether or not you are in the next room. So I dressed and came out."

"Ah!" he said, quietly. "Evidently I snore."

This explanation killed romance.

Iris retreated and the sailor, tired out at last, managed to close his weary eyes.

Next morning he hastily constructed a pole of sufficient length and strong enough to bear his weight, by tying two st.u.r.dy young trees together with ropes. Iris helped him to raise it against the face of the precipice, and he at once climbed to the ledge.

Here he found his observations of the previous night abundantly verified. The ledge was even wider than he dared to hope, nearly ten feet deep in one part, and it sloped sharply downwards from the outer lip of the rock. By lying flat and carefully testing all points of view, he ascertained that the only possible positions from which even a glimpse of the interior floor could be obtained were the branches of a few tall trees and the extreme right of the opposing precipice, nearly ninety yards distant. There was ample room to store water and provisions, and he quickly saw that even some sort of shelter from the fierce rays of the sun and the often piercing cold of the night might be achieved by judiciously rigging up a tarpaulin.

"This is a genuine bit of good luck," he mused. "Here, provided neither of us is. .h.i.t, we can hold out for a week or longer, at a pinch. How can it be possible that I should have lived on this island so many days and yet hit upon this nook of safety by mere chance, as it were?"

Not until he reached the level again could he solve the puzzle. Then he perceived that the way in which the cliff bulged out on both sides prevented the ledge from becoming evident in profile, whilst, seen _en plein face_ in the glare of the sunlight, it suggested nothing more than a slight indentation.

He rapidly sketched to Iris the defensive plan which the Eagle's Nest suggested. Access must be provided by means of a rope-ladder, securely fastened inside the ledge, and capable of being pulled up or let down at the will of the occupants. Then the place must be kept constantly stocked with a judicious supply of provisions, water, and ammunition.

They could be covered with a tarpaulin, and thus kept in fairly good condition.

"We ought to sleep there every night," he went on, and his mind was so engrossed with the tactical side of the preparations that he did not notice how Iris blanched at the suggestion.

"Surely not until danger actually threatens?" she cried.

"Danger threatens us each hour after sunset. It may come any night, though I expect at least a fortnight's reprieve. Nevertheless, I intend to act as if tonight may witness the first shot of the siege."

"Do you mean that?" she sighed. "And my little room is becoming so very cozy!"

Belle Vue Castle, their two-roomed hut, was already a home to them.

Jenks always accepted her words literally.

"Well," he announced, after a pause, "it may not be necessary to take up our quarters there until the eleventh hour. After I have hoisted up our stores and made the ladder, I will endeavor to devise an efficient cordon of sentinels around our position. We will see."

Not another word could Iris get out of him on the topic. Indeed, he provided her with plenty of work. By this time she could splice a rope more neatly than her tutor, and her particular business was to prepare no less than sixty rungs for the rope-ladder. This was an impossible task for one day, but after dinner the sailor helped her. They toiled late, until their fingers were sore and their backbones creaked as they sat upright.

Meanwhile Jenks swarmed up the pole again, and drew up after him a crowbar, the sledge-hammer, and the pickaxe. With these implements he set to work to improve the accommodation. Of course he did not attempt seriously to remove any large quant.i.ty of rock, but there were projecting lumps here and inequalities of floor there which could be thumped or pounded out of existence.

It was surprising to see what a clearance he made in an hour. The existence of the fault helped him a good deal, as the percolation of water at this point had oxidized the stone to rottenness. To his great joy he discovered that a few prods with the pick laid bare a small cavity which could be easily enlarged. Here he contrived a niche where Iris could remain in absolute safety when barricaded by stores, whilst, with a squeeze, she was entirely sheltered from the one dangerous point on the opposite cliff, nor need she be seen from the trees.

Having hauled into position two boxes of ammunition--for which he had scooped out a special receptacle--the invaluable water-kegs from the stranded boat, several tins of biscuits and all the tinned meats, together with three bottles of wine and two of brandy, he hastily abandoned the ledge and busied himself with fitting a number of gun-locks to heavy f.a.ggots.

Iris watched his proceedings in silence for some time. At last the interval for luncheon enabled her to demand an explanation.

"If you don't tell me at once what you intend to do with those strange implements," she said, "I will form myself into an amalgamated engineer and come out on strike."

"If you do," he answered, "you will create a precedent. There is no recorded case of a laborer claiming what he calls his rights when his life is at stake. Even an American tramp has been known to work like a fiend under that condition."

"Simply because an American tramp tries, like every other mere male, to be logical. A woman is more heroic. I once read of a French lady being killed during an earthquake because she insisted on going into a falling house to rescue that portion of her hair which usually rested on the dressing-table whilst she was asleep."

"I happen to know," he said, "that you are personally unqualified to emulate her example."

She laughed merrily, so lightly did yesterday's adventure sit upon her.

The allusion to her disheveled state when they were thrown ash.o.r.e by the typhoon simply impressed her as amusing. Thus quickly had she become inured to the strange circ.u.mstances of a new life.

"I withdraw the threat and subst.i.tute a more genuine plea--curiosity,"

she cried.

"Then you will be gratified promptly. These are our sentinels. Come with me to allot his post to the most distant one."

He picked up a f.a.ggot with its queer attachment, shouldered a Lee-Metford, and smiled when he saw the business-like air with which Iris slung a revolver around her waist.

They walked rapidly to Smugglers' Cove, and the girl soon perceived the ingenuity of his automatic signal. He securely bound the block of wood to a tree where it was hidden by the undergrowth. Breaking the bullet out of a cartridge, he placed the blank charge in position in front of the striker, the case being firmly clasped by a bent nail. To the trigger, the spring of which he had eased to a slight pressure, he attached a piece of unraveled rope, and this he carefully trained among the trees at a height of six inches from the ground, using as carriers nails driven into the trunks. The ultimate result was that a mere swish of Iris's dress against the taut cord exploded the cartridge.
