Uttering a low gasp in his despair, for the growling talk grew louder, he seized the great balls again, gave them another turn or two, and once more tried to stir the block, when his heart seemed to give a great jump, for it came right out as he exerted himself, with comparative ease, and directly after he had it hugged to his chest and was staggering and nearly falling headlong as he stepped down from the iron platform, making for the side. But he recovered himself, tottering on, and then in the darkness kicking against something soft--a sleeper--the encounter sending him, top-heavy as he was, crash against the bulwark, but doing all that he wanted, for the breech-block struck against the rail, glanced off, and went overboard, to fall with a tremendous splash, followed by another, which the middy made himself, as he half flung himself over, half rolled from the rail, to go down with the water thundering in his ears. The heaviness of his plunge naturally sent him below for some distance, but it was not long before he was rising again. It was long enough, though, for thought--and thoughts come quickly at a time like this. Fitz's first flash was a brilliant one, connected with his success, for the breech-block was gone beyond recovery; his next was one of horror, and connected with the sharks that haunted those waters; his third was full of despair; where was Poole, whom he seemed to have left to his fate? Hah! The surface again, and he could breathe; but which way to swim for the boat? There was none needed, for his shoulders were barely clear of the water when his arm was seized in a tremendous grip, another hand was thrust under his arm-pit, and he was literally jumped, dripping, into a boat, to pant out his first audible utterance for the past hour. It was only a word, and that was-- "Poole!" "I'm all right," came from out of the darkness close at hand. "Then give way, my lads, for your lives!" panted Fitz, and the oars began to splash. It was quite time, for there was no sleeping on board the gunboat now. All was rush and confusion; voices in Spanish were shouting orders, men hurrying here and there, a few shots were fired in their direction, evidently from revolvers, and then a steam-whistle was heard to blow, followed by a hissing, clanking sound, and the man who had hauled Fitz in over the bows put his face close to him and whispered-- "Steam-capstan. They're getting up their anchor. But there was three splashes, sir. What was that there first?" "The breech-block, Chips." "Hooroar!" It was some little time before another word was spoken, during which period the men had been rowing hard, and the boatswain, who had got hold of the rudder-lines, was steering almost at random for the shore, taking his bearings as well as he could from the gunboat, out of whose funnel sparks kept flying, and a lurid glare appeared upon the cloud of smoke which floated out, pointing to the fact that the stokers were hard at work.
