The shark had set its heart upon Granby, it appeared, for it turned slightly towards him, with the result that Noel rose to the surface, brushing against its very side, at which he viciously jabbed his knife, under water, without much effect, excepting to attract the brute towards himself. Then, getting his head out of the water, Noel placed his left arm over theshark's head, and made several stabs at the brute's eye with his right, which held the knife. But the position was awkward, and his blows missed their mark, though they seemed to rouse the fighting instincts of the huge fish, which lashed the water with its tail, and snapped viciously at its adversary, though clumsily, for it was in a bad position for taking its prey.

Meanwhile—for all this occupied but an instant of time—Granby had slipped back into the water, and swam behind his brother.

"Dive, Noel! Dive and rip up the beast from underneath!" he cried. These were the first words he had addressed to his brother for ten years.

"Keep out of his way then," said Noel, and dived.

But the shark would not be denied, for even as Noel dived and ripped a long slit that let the savage life out of it, the great brute made a last snap in Granby's direction, and with a cry Granby grew suddenly pale, and sank.

But help was at hand now. The cutter's crew had floated their boat with marvellous quickness, and were even now approaching, splashing with their oars in order to frighten away other sharks, of which there were many around.

Noel rose to the surface, having laid hold of Granby as he came; and as the dead shark sank, the two plucky officers were assisted into the boat. Granby was unconscious; and it was seen, to the horror of all present, that his right hand had been bitten clean off at the wrist.

For some days the ship's doctor almost despaired of saving the gallant fellow's life. The whole crew hung with dread and excitement upon his hourly report. Noel was frantic with anxiety. But the wounded man, like Noel, had been blessed with a good constitution; and, thanks to the doctor's skill and attention, to Noel's devotion, and to his own splendid strength, Granby gradually beat back oncoming death, and took a new lease of life, maimed, indeed, for life, but healed and recovered.
