Sudden as had been the accident, unexpectedly as it had swooped upon them, Billy Faraday had time to yell, at the top of his voice, a direction to the four others with him.

"Get ashore!" he cried; and had no time for more. He soused under the chilling flood; he went down and down, and finally, struggling, fighting for the surface, his head emerged, and he saw four other dark spots bobbing on the white, wind-whipped seas.

His advice had been sound. The island was comparatively close, and although the boat might be still afloat, if upside down, the shore offered the better chance of security. He struck out, and had the satisfaction of seeing the others do the same.

In point of fact, Patch could not swim more than a few strokes, and Jack was well aware of it. The two pals, who were always quarrelling in friendly fashion, were thrown out together, and Jack saw Septimus, after one or two wild strokes, vanish beneath the seas. He turned, and, rolling over on the surface, dived as cleanly as any Arab boy who plunges for pennies. He had been so quick that his hand caught at Patch's clothing, and in a moment he was hauling his chum to the surface. Arrived there, he made ready to swim ashore.

It was heavy going, for they were both in their clothes, and Jack was intensely grateful when a dark form slid over the waters and he recognized the overturned boat. With great difficulty he hauled Patch across the keel, where the young inventor hung on limply.

Shortly afterwards they felt the crunch of sand beneath the substance of the boat, and Jack knew that they were safe at last. Three drenched forms darted up and dragged the boat and its occupants ashore.

"I'd forgotten Patch was no swimmer," said Billy; "but we're safe enough now, thank goodness—this is Dog-face."

"Look here—there's an oar in the boat," said Jack. "We'll be able to scull back, at any rate, when the sea goes down."

"Better—one washed ashore before you came," said Billy. "We'll be able to row! But I'm thinking of how they'll be worrying about us back at Coll."

"Can't be helped, old fellow. Jingo, this wind's cutting!" He shivered. "I'm wet through—isn't there a place where we can shelter a bit?"
