Barr chafed silently. The reply was unanswerable.

Better to go slow than to run the ship ashore. Suddenly he snatched the binoculars from the man beside him and turned them on the aeroplane. He almost uttered a cry of triumph as the craft swung into his field of vision.

There was something the matter with her.

She was no longer rushing straight ahead.

As Luther Barr watched her he saw the great aircraft swoop in a huge circle above the town and then settle down so swiftly that it looked as if she must have been dashed to pieces. But the town was hidden behind a point and he could not see it.

"I hope she has been dashed to pieces," he gritted between his teeth savagely, "that would mean the saving of a lot of trouble for me."

But even as he prepared to put the binoculars back in the pocket alongside the binnacle with an evil smile playing about his thin lips, there came a startling shock.

Barr was almost thrown from his feet and only saved himself from falling by grasping a stanchion. The ship quivered from stem to stern as if she had been hit a staggering blow.

"We've struck a reef!" exclaimed the late bos'n.

"A reef!" yelled Barr, beside himself with fury.
