The petty strife of the elements was soothing to him. "They are snarling like whipped dogs," he said aloud. "One might almost fancy her ladyship the Moon appearing on the scene as a Uranian Venus, cowing sea and storm by the majesty of her presence."

Pleased with the conceit, he looked steadily at the brilliant luminary for some time. Then his eyes were attracted by the strong lights thrown upon the rugged face of the precipice into which the cavern burrowed. Unconsciously relieving his tired senses, he was idly wondering what trick of color Turner would have adopted to convey those sharp yet weirdly beautiful contrasts, when suddenly he uttered a startled exclamation.

"By Jove!" he murmured. "I never noticed that before."

The feature which so earnestly claimed his attention was a deep ledge, directly over the mouth of the cave, but some forty feet from the ground. Behind it the wall of rock sloped darkly inwards, suggesting a recess extending by haphazard computation at least a couple of yards. It occurred to him that perhaps the fault in the interior of the tunnel had its outcrop here, and the deodorizing influences of rain and sun had extended the weak point thus exposed in the bold panoply of stone.

He surveyed the ledge from different points of view. It was quite inaccessible, and most difficult to estimate accurately from the ground level. The sailor was a man of action. He chose the nearest tall tree and began to climb. He was not eight feet from the ground before several birds flew out from its leafy recesses, filling the air with shrill clucking.

"The devil take them!" he growled, for he feared that the commotion would awaken Iris. He was still laboriously worming his way through the inner maze of branches when a well-known voice reached him from the ground.

"Oh! so those wretched fowls aroused you?" he replied.

"Yes; but why did you arouse them?"

"I had a fancy to roost by way of a change"
