Great and important changes, as has been already mentioned, have been made in the armaments of all the smaller cruisers within the last few years. Half a generation since, a ship of the rate—we do not say of the size—of the vessel which was in chase of Spike and his craft, would not have had it in her power to molest an enemy at the distance these two vessels were now apart. But recent improvements have made ships of this nominal force formidable at nearly a league’s distance; more especially by means of their Paixhans and their shells.
For some little time the range carried the shot directly over the islet of the tent, Jack Tier and Rose, both of whom were watching all that passed with intense interest, standing in the open air the whole time, seemingly with no concern for themselves, so absorbed was each, notwithstanding all that had passed, in the safety of the brig. As for Rose, she thought only of Harry Mulford, and of the danger he was in by those fearful explosions of the shells. Her quick intellect comprehended the peculiar nature of the risk that was incurred by having the flour-barrels on deck, and she could not but see the manner in which Spike and his men were tumbling them into the water, as the quickest manner of getting rid of them. After what had just passed between Jack Tier and his commander, it might not be so easy to account for his manifest, nay, intense interest in the escape of the Swash. This was apparent by his troubled countenance, by his exclamations, and occasionally by his openly expressed wishes for her safety. Perhaps it was no more than the interest the seaman is so apt to feel in the craft in which he has long sailed, and which to him has been a home, and of which Mulford exhibited so much, in his struggles between feeling and conscience—between a true and a false duty.
As for Spike and his people, we have already mentioned their efforts to get rid of the powder. Shell after shell exploded, though none very near the brig, the ship working her guns as if in action. At length the officers of the sloop-of-war detected a source of error in their aim, that is of very common occurrence in sea-gunnery. Their shot had been thrown to ricochet, quartering a low, but very regular succession of little waves. Each shot striking the water at an acute angle to its agitated surface, was deflected from a straight line, and described a regular curve toward the end of its career; or, it might be truer to say, an irregular curvature, for the deflection increased as the momentum of the missile diminished.
No sooner did the commanding officer of the sloop-of-war discover this fact, and it was easy to trace the course of the shots by the jets of water they cast into the air, and to see as well as to hear the explosions of the shells, than he ordered the guns pointed more to windward, as a means of counteracting the departure from the straight lines. This expedient succeeded in part, the solid shot falling much nearer to the brig the moment the practice was resorted to. No shell was fired for some little time after the new order was issued, and Spike and his people began to hope these terrific missiles had ceased their annoyance. The men cheered, finding their voices for the first time since the danger had seemed so imminent, and Spike was heard animating them to their duty. As for Mulford, he was on the coach-house deck, working the brig, the captain having confided to him that delicate duty, the highest proof he could furnish of confidence in his seamanship. The handsome young mate had just made a half-board, in the neatest manner, shoving the brig by its means through a most difficult part of the passage, and had got her handsomely filled again on the same tack, looking right out into open water, by a channel through which she could now stand on a very easy bowline. Every thing seemed propitious, and the sloop-of-war’s solid shot began to drop into the water, a hundred yards short of the brig. In this state of things one of the Paixhans belched forth its angry flame and sullen roar again. There was no mistaking the gun. Then came its mass of iron, a globe that would have weighed just sixty-eight pounds, had not sufficient metal been left out of its interior to leave a cavity to contain a single pound of powder. Its course, as usual, was to be marked by its path along the sea, as it bounded half a mile at a time, from wave to wave. Spike saw by its undeviating course that this shell was booming terrifically toward his brig, and a cry to “look out for the shell,” caused the work to be suspended. That shell struck the water for the last time, within two hundred yards of the brig, rose dark and menacing in its furious leap, but exploded at the next instant. The fragments of the iron were scattered on each side, and ahead. Of the last, three or four fell into the water so near the vessel as to cast their spray on her decks.
“Overboard with the rest of the powder!” shouted Spike. “Keep the brig off a little, Mr. Mulford—keep her off, sir; you luff too much, sir.”
“Ay, ay, sir,” answered the mate. “Keep her off, it is.”
“There comes the other shell!” cried Ben, but the men did not quit their toil to gaze this time. Each seaman worked as if life and death depended on his single exertions. Spike alone watched the course of the missile. On it came, booming and hurtling through the air, tossing high the jets, at each leap it made from the surface, striking the water for its last bound, seemingly in a line with the shell that had just preceded it. From that spot it made its final leap. Every hand in the brig was stayed and every eye was raised as the rushing tempest was heard advancing. The mass went muttering directly between the masts of the Swash. It had scarcely seemed to go by when the fierce flash of fire and the sharp explosion followed. Happily for those in the brig, the projectile force given by the gun carried the fragments from them, as in the other instance it had brought them forward; else would few have escaped mutilation, or death, among their crew.
The flashing of fire so near the barrels of powder that still remained on their deck, caused the frantic efforts to be renewed, and barrel after barrel was tumbled overboard, amid the shouts that were now raised to animate the people to their duty.
“Luff, Mr. Mulford—luff you may, sir,” cried Spike.
