Onward went the ship, now plunging into a vast hollow, which threatened to engulf her; now she rose rapidly to the top of another sea, while on either side they appeared to be vying with each other, which could leap the highest and accomplish her destruction.

The officers were gathered aft, the men in the waist, holding on firmly to the stanchions, or anything to which they could secure themselves. Each time that the ship plunged her head into the seas, the masts bent, as if every moment they would go by the board. At length a lull came, and the commander, having consulted with Green, fearing dangers ahead, determined to bring the ship to, an operation attended by considerable risk, as a sea striking her at the moment might sweep her deck. A favourable opportunity was waited for. The crew stood ready to lower the fore-topsail and hoist the main-topsail, which had been closely reefed. Both tasks were accomplished; the officers were anxiously watching the seas as the ship rode over them, but happily she was safely rounded to, and now lay with her main-topsail to the mast, though scarcely had she got into that position, than a fierce foam-crested sea, roaring up, struck her bows and deluged her decks, but shaking herself clear, like a thing of life, she sprang forward, while the water rushed through the ports. The lull continued, and many hoped that the gale was breaking; but in less than an hour another furious squall struck the ship, and nearly laid her over on her beam ends. Once more she rose, her stout canvas having stood the severe trial to which it had been put, and she rode with comparative ease for a few minutes.

The seas, however, seemed to become more broken than ever. A prodigious one came roaring towards the weather bow. The Dragon appeared to see her danger, and struggled to avoid it, but the next instant she pitched headlong into a deep hollow, when another monstrous wave, rising apparently half as high as the foretop, fell completely down on her deck. For a few seconds, her commander and his officers feared that she would never again rise. No orders could be issued, and nothing could be done. The crew stood silently at their stations, not uttering a word, or showing that they felt the fearful predicament in which they were placed.

The ship remained, as it were, fixed in the sea; then with a sudden jerk she burst her way through it, but her stout bowsprit was broken short off, and the next sea threw the wreck of it across the forecastle. The commander’s voice was now heard in tones vying with the howling of the gale. The crew, obedient to his orders, rushed forward to secure the bowsprit with lashings; while the boatswain, with another gang, lost not a moment in setting up fresh stays, to prevent the foremast being carried away.

This, with the loss of one of the boats, and the forepart of the bulwarks stove in, were the chief damages hitherto received by the Dragon during the gale. It was not over, however. Again the sun set, and the wind continued to rage with unabated fury. The watch below had been ordered to turn in, but few of the officers had done so, and, though tired out, still remained on deck. Tom and Archie were standing aft, close together, when the latter suddenly grasped Tom by the arm.

“Oh, mon! what’s that?” he exclaimed, pointing to the main-topmast head, which appeared crowned by a ball of pale fire.

“It has a curious appearance; though I never saw it before, my brother Jack has told me about it. It is a sort of Jack-o’-lantern, or Will-o’-the-wisp, or, as Gerald once called it, ‘Saint Vitus’ dance.’ I believe he meant to say Saint Elmo’s fire.”

While the midshipmen were gazing up, the flame descended rapidly down the mast, running first along the main topgallant yardarm, then returning, down it came, to the main-topsail yard, where it glided out to the extreme end. Here it rested for some seconds, as if it had not made up its mind what next to do. Presently back it came to the mast, and darted out to the lee yardarm. It had not yet finished its journey. Once more gliding back, it ascended the mast, when it made its way by the main-topmast stay, on to the foremast and there went gliding backwards and forwards along the yard.

“I wish it would come down on deck, and then we might have a chance of catching it,” said Tom. “I have read somewhere that a man going aloft with a bucket, clapped it over the light, and brought it down a prisoner. It is a sort of gas which is driven about through the air until it finds something to rest on. Why it goes moving up and down in that curious way I don’t know, nor does anybody else, I believe. I wish the doctor were on deck,—he would tell us.”

“Shall I call him?” asked Archie.
