Tarzan, who had been thrown some distance by the shell burst, was swimming toward Bubonovitch and Douglas when he heard the former's warning. Diving quickly beneath the surface, he drew his knife. A few swift, strong strokes brought him close to the shark. A mighty surge of his knife arm ripped open the belly of the huge fish, disembowling it. It released its hold on van der Bos and turned on Tarzan, but the man eluded its jaws and struck again and again with his knife.
The water was red with blood as another shark darted in and attacked its fellow. The first shark swam sluggishly away while the other bit and tore at it. For the moment the survivors were freed from one menace, but the bullets still pinged close.
With Tarzan's help, Bubonovitch and Douglas got van der Bos to a large piece of wreckage—one of the outrigger floats. Tarzan tore a strip from what remained of van der Bos's trousers, and while he and Douglas held the man on the float, Bubonovitch applied a tourniquet. Tak still breathed, but fortunately he was unconscious.
Bubonovitch shook his head. "He ain't got a chance," he said. "But then, neither have we."
"The sharks are going to have plenty good feeding today," said Douglas . They were all looking at the Jap ship. Again the rail was lined with bandy legged little men. Some of them were firing pistols at the people in the water. Keta, perched on a piece of wreckage, scolded and threatened.
There was a terriffic detonation. A great fan shaped burst of flame shot hundreds of feet into the air from amidships of the merchantman, and a pillar of smoke rose hundreds of feet higher. A second explosion followed and the ship broke in two, the bow hurled almost clear of the water. The two halves sunk almost immediately, leaving a few scorched and screaming creatures struggling in burning oil.
For a few moments the survivors of the proa looked on in stunned silence, which was broken by Rosetti. "I knew She'd hear me," he said. "She ain't ever failed me yet."
"She'll have to pull a real miracle yet to get us out of the middle of the Indian Ocean before we drown or the sharks get us," said Jerry.
"Pray like hell, Shrimp," said Bubonovitch.
"Don't think I ain't, brother," said Rosetti.
"Look! Look!" shouted Corrie, pointing.
Three hundred yards beyond the burning oil a submarine was surfacing. The Union Jack was painted on the side of its conning tower.
"There's your miracle, Cap'n," said Rosetti. "She ain't ever failed me yet. I mean in a real pinch."
"What do you think of the British now, sergeant?" asked Tarzan, smiling.
"I love 'em," said Rosetti.
The sub circled to windward of the burning oil and drew alongside the wreckage of the proa. The hatch spewed men to haul the castaways aboard. Tarzan and Bubonovitch passed van der Bos up first. He died as they laid him gently on the deck.
Corrie and Sarina followed, and then the men. Lt. Cmdr. Bolton, skipper of the sub, was full of amazement and questions. Corrie knelt beside van der Bos's body, trying to hold back the teers. Jerry joined her.
"Poor Tak," she said.
They did not take him below. He was buried at sea, Bolton reading the burial service. Then they all went below for dry clothing and hot coffee, and presently the sorrow and depression seemed less, for they were all young and they had all seen much of death.
When Bolton heard their story, he said, "Well, you have certainly played in luck from the start; but my happening to be right where I was when you needed me is little short of a miracle."
"It hasn't been luck, sir," said Rosetti. "It's been Holy Mary, Mother of Jesus from start to finish, including the miracle."
"I can well believe it," said Bolton , "for none of you has any business being alive now, by all the laws of chance. Nothing but divine intervention could have preserved you. It even arranged that I saved my last two fish for that Jap. You really should all be dead."
"Mary certainly helped in a pinch," said Jerry, "but if Tarzan hadn't been on the job all the time, pinch hitting for her, we'd have been sunk months ago."
"Well," said Bolton , "I think you won't have to call on either Mary or Tarzan from now on. I'm ordered to Sydney , and it won't be so long now before you can sit down in Ushers Hotel with a steak and kidney pie in front of you."
"And drink warm beer," said Bubonovitch.
Later that evening Jerry and Rosetti approached Bolton . "Captain," said the former, "are you authorized to perform marriage ceremonies at sea?"
"I certainly am."
"Then you got two jobs right now, skipper," said Rosetti.
THE END
