"I thought you might get into mischief," she confessed.

"No. On the other hand, I am trying to make trouble for any unwelcome visitors," he replied. "This is a cheval de frise, which I intend to set up in front of our cave in case we are compelled to defend ourselves against an attack by savages. With this barring the way they cannot rush the position."

She sighed. Rainbow Island was a wild spot after all. Did not thorns and briers grow very close to the gates of Eden?

On the nineteenth day of their residence on the island the sailor climbed, as was his invariable habit, to the Summit Rock whilst Iris prepared breakfast. At this early hour the horizon was clearly cut as the rim of a sapphire. He examined the whole arc of the sea with his glasses, but not a sail was in sight. According to his calculations, the growing anxiety as to the fate of the Sirdar must long ere this have culminated in the dispatch from Hong Kong or Singapore of a special search vessel, whilst British warships in the China Sea would be warned to keep a close lookout for any traces of the steamer, to visit all islands on their route, and to question fishermen whom they encountered. So help might come any day, or it might be long deferred. He could not pierce the future, and it was useless to vex his soul with questionings as to what might happen next week. The great certainty of the hour was Iris—the blue-eyed, smiling divinity who had come into his life—waiting for him down there beyond the trees, waiting to welcome him with a sweet-voiced greeting; and he knew, with a fierce devouring joy, that her cheek would not pale nor her lip tremble when he announced that at least another sun must set before the expected relief reached them.

He replaced the glasses in their case and dived into the wood, giving a passing thought to the fact that the wind, after blowing steadily from the south for nearly a week, had veered round to the north-east during the night. Did the change portend a storm? Well, they were now prepared for all such eventualities, and he had not forgotten that they possessed, among other treasures, a box of books for rainy days. And a rainy day with Iris for company! What gale that ever blew could offer such compensation for enforced idleness?

The morning sped in uneventful work. Iris did not neglect her cherished pitcher-plant. After luncheon it was her custom now to carry a dishful of water to its apparently arid roots, and she rose to fulfil her self-imposed task.

"Let me help you," said Jenks. "I am not very busy this afternoon."

"No, thank you. I simply won't allow you to touch that shrub. The dear thing looks quite glad to see me. It drinks up the water as greedily as a thirsty animal."

"Even a cabbage has a heart, Miss Deane."

She laughed merrily. "I do believe you are offering me a compliment," she said. "I must indeed have found favor in your eyes."
