Miss Iris had meant her playful retort as a mere light-hearted quibble.

It annoyed her, a young person of much consequence, to have her kindly condescension repelled.

"I suppose so," she agreed; "but I have gone through so much in a few hours that I am bewildered, apt to forget these nice distinctions."

Where these two quareling, or flirting? Who can tell?

Jenks was closely examining the reef on which the _Sirdar_ struck.

Some square objects were visible near the palm tree. The sun, glinting on the waves, rendered it difficult to discern their significance.

"What do you make of those?" he inquired, handing the gla.s.ses, and blandly ignoring Miss Deane's petulance. Her brain was busy with other things while she twisted the binoculars to suit her vision. Rainbow Island--Iris--it was a nice conceit. But "menial" struck a discordant note. This man was no menial in appearance or speech. Why was he so deliberately rude?

"I think they are boxes or packing-cases," she announced.

"Ah, that was my own idea. I must visit that locality."

"How? Will you swim?"

"No," he said, his stern lips relaxing in a smile, "I will not swim; and by the way, Miss Deane, be careful when you are near the water. The lagoon is swarming with sharks at present. I feel tolerably a.s.sured that at low tide, when the remnants of the gale have vanished, I will be able to walk there along the reef."

"Sharks!" she cried. "In there! What horrible surprises this speck of land contains! I should not have imagined that sharks and seals could live together."

"You are quite right," he explained, with becoming gravity. "As a rule sharks infest only the leeward side of these islands. Just now they are attracted in shoals by the wreck."

"Oh." Iris shivered slightly.

"We had better go back now. The wind is keen here, Miss Deane."

[Ill.u.s.tration: HE WAS SO BUSY THAT HE PAID LITTLE HEED TO IRIS, BUT THE ODOR OF FRIED HAM WAS WAFTED TO HIM]

She knew that he purposely misunderstood her gesture. His att.i.tude conveyed a rebuke. There was no further room for sentiment in their present existence; they had to deal with chill necessities. As for the sailor, he was glad that the chance turn of their conversation enabled him to warn her against the lurking dangers of the lagoon. There was no need to mention the devil-fish now; he must spare her all avoidable thrills.

They gathered the stores from the first _al fresco_ dining-room and reached the cave without incident. Another fire was lighted, and whilst Iris attended to the kitchen the sailor felled several young trees. He wanted poles, and these were the right size and shape. He soon cleared a considerable s.p.a.ce. The timber was soft and so small in girth that three cuts with the axe usually sufficed. He dragged from the beach the smallest tarpaulin he could find, and propped it against the rock in such manner that it effectually screened the mouth of the cave, though admitting light and air.

He was so busy that he paid little heed to Iris. But the odor of fried ham was wafted to him. He was lifting a couple of heavy stones to stay the canvas and keep it from flapping in the wind, when the girl called out--

"Wouldn't you like to have a wash before dinner?"

He straightened himself and looked at her. Her face and hands were shining, spotless. The change was so great that his brow wrinkled with perplexity.

"I am a good pupil," she cried. "You see I am already learning to help myself. I made a bucket out of one of the dish-covers by slinging it in two ropes. Another dish-cover, some sand and leaves supplied basin, soap, and towel. I have cleaned the tin cups and the knives, and see, here is my greatest treasure."

She held up a small metal lamp.

"Where in the world did you find that?" he exclaimed.

"Buried in the sand inside the cave."

"Anything else?"

His tone was abrupt She was so disappointed by the seeming want of appreciation of her industry that a gleam of amus.e.m.e.nt died from her eyes and she shook her head, stooping at once to attend to the toasting of some biscuits.

This time he was genuinely sorry.

"Forgive me, Miss Deane," he said penitently. "My words are dictated by anxiety. I do not wish you to make discoveries on your own account.

This is a strange place, you know--an unpleasant one in some respects."

"Surely I can rummage about my own cave?"

"Most certainly. It was careless of me not to have examined its interior more thoroughly."

"Then why do you grumble because I found the lamp?"

"I did not mean any such thing. I am sorry."

"I think you are horrid. If you want to wash you will find the water over there. Don't wait. The ham will be frizzled to a cinder."

Unlucky Jenks! Was ever man fated to incur such unmerited odium? He savagely laved his face and neck. The fresh cool water was delightful at first, but it caused his injured nail to throb dreadfully. When he drew near to the fire he experienced an unaccountable sensation of weakness. Could it be possible that he was going to faint? It was too absurd. He sank to the ground. Trees, rocks, and sand-strewn earth indulged in a mad dance. Iris's voice sounded weak and indistinct. It seemed to travel in waves from a great distance. He tried to brush away from his brain these dim fancies, but his iron will for once failed, and he pitched headlong downwards into darkness.

When he recovered the girl's left arm was round his neck. For one blissful instant he nestled there contentedly. He looked into her eyes and saw that she was crying. A gust of anger rose within him that he should be the cause of those tears.

"d.a.m.n!" he said, and tried to rise.

"Oh! are you better?" Her lips quivered pitifully.

"Yes. What happened? Did I faint?"

"Drink this."

She held a cup to his mouth and he obediently strove to swallow the contents. It was champagne. After the first spasm of terror, and when the application of water to his face failed to restore consciousness, Iris had knocked the head off the bottle of champagne.

He quickly revived. Nature had only given him a warning that he was overdrawing his resources. He was deeply humiliated. He did not conceive the truth, that only a strong man could do all that he had done and live. For thirty-six hours he had not slept. During part of the time he fought with wilder beasts than they knew at Ephesus. The long exposure to the sun, the mental strain of his foreboding that the charming girl whose life depended upon him might be exposed to even worse dangers than any yet encountered, the physical labor he had undergone, the irksome restraint he strove to place upon his conduct and utterances--all these things culminated in utter relaxation when the water touched his heated skin.

But he was really very much annoyed. A powerful man always is annoyed when forced to yield. The revelation of a limit to human endurance infuriates him. A woman invariably thinks that the man should be scolded, by way of tonic.

"How _could_ you frighten me so?" demanded Iris, hysterically.

"You must have felt that you were working too hard. You made me rest.

Why didn't you rest yourself?"

He looked at her wistfully. This collapse must not happen again, for her sake. These two said more with eyes than lips. She withdrew her arm; her face and neck crimsoned.

"There," she said with compelled cheerfulness. "You are all right now.

Finish the wine."

He emptied the tin. It gave him new life. "I always thought," he answered gravely, "that champagne was worth its weight in gold under certain conditions. These are the conditions."

Iris reflected, with elastic rebound from despair to relief, that men in the lower ranks of life do not usually form theories on the expensive virtues of the wine of France. But her mind was suddenly occupied by a fresh disaster.

"Good gracious!" she cried. "The ham is ruined."
