"Oh. I see!" he growled, and he too reddened.

"I can't help it, can I?" she demanded piteously. "It is not unlike a riding-habit, is it?"

Then his ready wit helped him.

"An excellent compromise," he cried. "A process of evolution, in fact.

Now, do you know, Miss Deane, that would never have occurred to me."

And during the remainder of the day he did not once look at her feet.

Indeed, he had far more serious matters to distract his thoughts, for Iris, feverishly anxious to be busy, suddenly suggested that it would be a good thing were she able to use a rifle if a fight at close quarters became necessary.

The recoil of the Lee-Metford is so slight that any woman can manipulate the weapon with effect, provided she is not called upon to fire from a standing position, in which case the weight is liable to cause bad aiming. Though it came rather late in the day, Jenks caught at the idea. He accustomed her in the first instance to the use of blank cartridges. Then, when fairly proficient in holding and sighting--a child can learn how to refill the clip and eject each empty sh.e.l.l--she fired ten rounds of service ammunition. The target was a white circle on a rock at eighty yards, and those of the ten shots that missed the absolute mark would have made an enemy at the same distance extremely uncomfortable.

Iris was much pleased with her proficiency. "Now," she cried, "instead of being a hindrance to you I may be some help. In any case, the Dyaks will think there are two men to face, and they have good reason to fear one of us."

Then a new light dawned upon Jenks.

"Why did you not think of it before?" he demanded. "Don't you see, Miss Deane, the possibility suggested by your words? I am sorry to be compelled to speak plainly, but I feel sure that if those scoundrels do attack us in force it will be more to secure you than to avenge the loss of their fellow tribesmen. First and foremost, the sea-going Dyaks are pirates and marauders. They prowl about the coast looking not so much for a fight as for loot and women. Now, if they return, and apparently find two well-armed men awaiting them, with no prospect of plunder, there is a chance they may abandon the enterprise."

Iris did not flinch from the topic. She well knew its grave importance.

"In other words," she said, "I must be seen by them dressed only in male clothing?"

"Yes, as a last resource, that is. I have some hope that they may not discover our whereabouts owing to the precautions we have adopted.

Perched up there on the ledge we will be profoundly uncomfortable, but that will be nothing if it secures our safety."

She did not reply at once. Then she said musingly--"Forty-four days!

Surely there has been ample time to scour the China Sea from end to end in search of us? My father would never abandon hope until he had the most positive knowledge that the _Sirdar_ was lost with all on board."

The sailor, through long schooling, was prepared with an answer--"Each day makes the prospect of escape brighter. Though I was naturally disappointed this morning, I must state quite emphatically that our rescue may come any hour."

Iris looked at him steadily.

"You wear a solemn face for one who speaks so cheerfully," she said.

"You should not attach too great significance to appearances. The owl, a very stupid bird, is noted for its philosophical expression."

"Then we will strive to find wisdom in words. Do you remember, Mr.

Jenks, that soon after the wreck you told me we might have to remain here many months?"

"That was a pardonable exaggeration."

"No, no. It was the truth. You are seeking now to buoy me up with false hope. It is sixteen hundred miles from Hong Kong to Singapore, and half as much from Siam to Borneo. The _Sirdar_ might have been driven anywhere in the typhoon. Didn't you say so, Mr. Jenks?"

He wavered under this merciless cross-examination.

"I had no idea your memory was so good," he said, weakly.

"Excellent, I a.s.sure you. Moreover, during our forty-four days together, you have taught me to think. Why do you adopt subterfuge with me? We are partners in all else. Why cannot I share your despair as well as your toil?"

She blazed out in sudden wrath, and he understood that she would not be denied the full extent of his secret fear. He bowed reverently before her, as a mortal paying homage to an angry G.o.ddess.

"I can only admit that you are right," he murmured. "We must pray that G.o.d will direct our friends to this island. Otherwise we may not be found for a year, as unhappily the fishermen who once came here now avoid the place. They have been frightened by the contents of the hollow behind the cliff. I am glad you have solved the difficulty unaided, Miss Deane. I have striven at times to be coa.r.s.e, even brutal, towards you, but my heart flinched from the task of telling you the possible period of your imprisonment."

Then Iris, for the first time in many days, wept bitterly, and Jenks, blind to the true cause of her emotion, picked up a rifle to which, in spare moments, he had affixed a curious device, and walked slowly across Prospect Park towards the half-obliterated road leading to the Valley of Death.

The girl watched him disappear among the trees. Through her tears shone a sorrowful little smile.

"He thinks only of me, never of himself," she communed. "If it pleases Providence to spare us from these savages, what does it matter to me how long we remain here? I have never been so happy before in my life.

I fear I never will be again. If it were not for my father's terrible anxiety I would not have a care in the world. I only wish to get away, so that one brave soul at least may be rid of needless tortures. All his worry is on my account, none on his own."

That was what tearful Miss Iris thought, or tried to persuade herself to think. Perhaps her cogitations would not bear strict a.n.a.lysis.

Perhaps she harbored a sweet hope that the future might yet contain bright hours for herself and the man who was so devoted to her. She refused to believe that Robert Anstruther, strong of arm and clear of brain, a Knight of the Round Table in all that was n.o.ble and chivalric, would permit his name to bear an unwarrantable stigma when--and she blushed like a June rose--he came to tell her that which he had written.

The sailor returned hastily, with the manner of one hurrying to perform a neglected task. Without any explanation to Iris he climbed several times to the ledge, carrying arm-loads of gra.s.s roots which he planted in full view. Then he entered the cave, and, although he was furnished only with the dim light that penetrated through the distant exit, she heard him hewing manfully at the rock for a couple of hours. At last he emerged, grimy with dust and perspiration, just in time to pay a last visit to Summit Rock before the sun sank to rest. He asked the girl to delay somewhat the preparations for their evening meal, as he wished to take a bath, so it was quite dark when they sat down to eat.

Iris had long recovered her usual state of high spirits.

"Why were you burrowing in the cavern again?" she inquired. "Are you in a hurry to get rich?"

"I was following an air-shaft, not a lode," he replied. "I am occasionally troubled with after wit, and this is an instance. Do you remember how the flame of the lamp flickered whilst we were opening up our mine?"

"Yes."

"I was so absorbed in contemplating our prospective wealth that I failed to pay heed to the true significance of that incident. It meant the existence of an upward current of air. Now, where the current goes there must be a pa.s.sage, and whilst I was busy this afternoon among the trees over there,"--he pointed towards the Valley of Death--"it came to me like an inspiration that possibly a few hours' hewing and delving might open a shaft to the ledge. I have been well rewarded for the effort. The stuff in the vault is so eaten away by water that it is no more solid than hard mud for the most part. Already I have scooped out a chimney twelve feet high."

"What good can that be?"

"At present we have only a front door--up the face of the rock. When my work is completed, before tomorrow night I hope, we shall have a back door also. Of course I may encounter unforeseen obstacles as I advance.

A twist in the fault would be nearly fatal, but I am praying that it may continue straight to the ledge."

"I still don't see the great advantage to us."

"The advantages are many, believe me. The more points of attack presented by the enemy the more effective will be our resistance. I doubt if they would ever be able to rush the cave were we to hold it, whereas I can go up and down our back staircase whenever I choose. If you don't mind being left in the dark I will resume work now, by the light of your lamp."

But Iris protested against this arrangement. She felt lonely. The long hours of silence had been distasteful to her. She wanted to talk.

"I agree," said Jenks, "provided you do not pin me down to something I told you a month ago."

"I promise. You can tell me as much or as little as you think fit. The subject for discussion is your court-martial."

He could not see the tender light in her eyes, but the quiet sympathy of her voice restrained the protest prompt on his lips. Yet he blurted out, after a slight pause--

"That is a very unsavory subject."

"Is it? I do not think so. I am a friend, Mr. Jenks, not an old one, I admit, but during the past six weeks we have bridged an ordinary acquaintanceship of as many years. Can you not trust me?"

Trust her? He laughed softly. Then, choosing his words with great deliberation, he answered--"Yes, I can trust you. I intended to tell you the story some day. Why not tonight?"
