“Stretch out to your work, lads,” he exclaimed, as the oars dashed into the water; “throw your whole hearts into it; the fire must be close to the magazine, and—”

A terrific concussion, a dull heavy roar, and the poor old “Proselyte” was rent to pieces, as a broad sheet of flame flashed up from her hull skyward. A wall of water some five feet high leapt up just under our stern, and immediately afterwards curled over upon us, completely swamping the boat. Fragments of planks and beams, heavy bolts, spars, and other wreckage whizzed through the air all around us; and one of the guns, still mounted on its carriage, and with its shattered tackles streaming in the air, was hurled outwards and fell into the water with a tremendous splash, within six feet of where we were all left struggling in the water. Then a great cloud of black smoke shot up into the air; and the blackened remains of the hull, collapsing amidships, sank out of sight, creating a great seething whirl, which dragged us all helplessly into its vortex, and sucked us ruthlessly down, down deep into the darkening bosom of the ocean.

Stunned, and almost insensible from the violence of the shock, I still had presence of mind left to close my nostrils with the fingers of one hand, and to hold my breath, as I was helplessly whirled hither and thither; and at last, just as my powers of endurance had reached the point of exhaustion, I rose again to the surface, and beheld once more the welcome sight of the bright sunlight flashing upon the dancing billows.

The water all round me was thickly strewn with wreckage; and a few pieces were still falling here and there, showing the height to which the fragments had been projected. A dozen or so of human heads appeared on the surface of the water at no great distance from me; and others were momentarily popping up above the waves; the owners, one and all, immediately striking out, more or less scientifically, for the nearest floating object.

Looking round me, I soon had the satisfaction of discovering the gallant commander of the ill-fated “Proselyte,” clinging to the keel of our boat, which was floating bottom-up at no great distance from me. Seeing that all hands appeared pretty well able to take care of themselves, I at once struck out and joined him.

“Ah! Mr Chester,” he exclaimed, as I ranged alongside, “glad to see that you have weathered it so well. It was a very narrow squeak; and we have come out of it a good deal better than I dared expect. I have been trying to count heads, and I make out thirty-eight, all told; how many men had you with you?”

“Twelve,” I answered.

“Twelve?” he repeated, “then that brings us out all right, for I counted twenty-four of my people as they passed down into the boat, and I make twenty-five, which, with you and your dozen, brings up the complement. Here come the boats to pick us up. I have no doubt the explosion has frightened all the sharks within a dozen miles of us, and started them off to seaward under a heavy press of sail; otherwise I should not feel quite so easy in my mind about those poor fellows. Some of them are clinging to very small pieces of wreckage, and would have no chance if attacked.”

I remarked that I thought there was not very much danger; an opinion which soon received singular confirmation; for while we were still speaking, immense numbers of fish of all sizes and descriptions, some killed, and others merely stunned by the violence of the explosion, floated up to the surface; and shortly afterwards, when the boats had picked us all up, and we were pulling out toward the fleet, we fell in with an enormous shark, floating helplessly on his back, in an apparently paralysed condition. A running bowline was promptly slipped over his tail and drawn taut; and he was triumphantly and unresistingly towed alongside the “Victory,” and hoisted inboard.
