When the lads returned on deck, they found that the Ajax had made another complete circle of the wreck, this time covering the first film of oil with a thicker one. They were much closer to the wreck now. Jack could count two figures in the bow and three astern.

But even as they looked, both boys gave a cry of horror. A huge wave had swept clear over the floundering hulk, and when it vanished one of the men in the stern had vanished, too.

“Oh! That’s terrible!” exclaimed Jack. “Why don’t we launch a boat?”

“No use sacrificing more lives,” said Raynor, with forced calmness, although he was white about the lips. “Braceworth knows what he’s doing, I reckon.”

“Yes, but to watch those poor fellows—it’s—it’s awful!”

Jack put his hands over his eyes to shut out, for an instant, the frantically waving arms of the men on the wreck. They were making desperate appeals. Plainly they could not understand why the liner kept circling them.

“Brace up, youngster,” said Raynor kindly. “I guess the skipper feels as bad about it as you do, but he won’t act till he can do so safely.”

The afternoon began to close in. The stormy twilight deepened into dusk and found the nerve-wracking waiting still going on. On the great gray seas the black steamer, with a wind-blown plume of smoke pouring from her salt-encrusted funnel, still solemnly circled the foundering hulk, while the storm clouds raced past overheard.

But the wind had dropped slightly and the coat of oil that now covered the waves prevented their breaking. The Ajax, already crawling up on the weather side of the wreck, appeared to reduce speed.

“There’s going to be something doing now,” prophesied Raynor.
