Once embarked in the fairway, the management of the catamaran occupied his mind to the complete exclusion of all other problems. He was puzzled by the discovery that the awkward craft was traveling too far to the westward, until he remembered that the tide had turned, and that the current was either slack or running in the opposite direction. Changing the paddle to the starboard side, he soon corrected this deviation in the route. But he had been carried already a hundred yards or more out of the straight line. To reach the two pointed rocks that marked the entrance to the secret channel, he was obliged to creep back along the whole shoreward face of the Grand-père; and to this accident was due a surprise that ranked high in a day replete with marvels.

When the catamaran rounded the last outlying crag, and they were all straining their eyes to find the sentinel pillars, they became aware that a small boat was being pulled cautiously toward them from the opposite side of the rock.

Iris gasped. She heard Hozier mutter under his breath, while San Benavides revealed his dismay by an oath and a convulsive tightening of the hands that rested on the girl's shoulders.

Hozier strove with a few desperate strokes of the paddle to reach the shadows of the passage before the catamaran was seen by the boat's occupants. He might have succeeded. Many things can happen at night and on the sea—strange escapades and hair's-breadth 'scapes—thrills denied to stay-at-homes dwelling in cities, who seldom venture beyond a lighted area. But there was even a greater probability that the unwieldy catamaran might be caught by the swell and dashed side-long against one of the half-submerged rocks that thrust their black fangs above the water.

Happily, they were spared either alternative. At the very instant that their lot must be put to the test of chance, Coke's hoarse accents came to their incredulous ears.

"Let her go, Olsen," he was growling. "We've a clear course now, an' that dam moon will spile everything if we're spotted."

In this instance hearing was believing, and Philip was the first to guess what had actually occurred.

"Boat ahoy, skipper!" he sang out in a joyous hail.

Coke stood up. He glared hard at the reef.

"Did ye 'ear it?" he cried to De Sylva, who was steering. "Sink me, I 'ope I ain't a copyin' pore ole Watts, but if that wasn't Hozier's voice I'm goin' dotty."
