ERRORS EXCEPTED.

It was Thursday the eleventh, in the small hours of the morning. The Albatross was lumbering along as best she might with her broken engine, and we were nearing the line of 180°. We weren't making much way, however, for the speed was low; and we hadn't so much reason for hurrying now, for we felt almost hopeless of being in time to prevent the threatened massacre. Our people, we feared, had long since fallen victims to the superstition and bloodthirstiness of the ungrateful savages.

I was asleep in my berth after the fatigues of the day, and was dreaming of my dear little girl in England; when suddenly I felt a clammy cold hand laid upon my own outside the coverlet, and waking with a start, I saw Martin Luther standing pale and white in his blue shirt and trousers before me. I knew at once by his face something fresh had turned up.

"Goodness gracious, boy," I exclaimed, "what on earth's the matter now?"

"Captain Braithwaite," he answered with very solemn seriousness, "I've been counting the days over and over again, and I'm quite sure there's a mistake somewhere. We've got a day wrong in our reckoning, I'm certain. I've counted up each day and night a hundred times over since we left Tanaki in the boat—Jack and I—and I feel confident you're twenty-four hours out in your reckoning. Yesterday wasn't Wednesday the tenth at all. It was Tuesday the ninth, and we may yet reach Tanaki in time to save them."

"No, no, my boy," I answered, "you're wrong; you're wrong. Your natural anxiety about your father's fate has upset your calculations. To-day's the eleventh; yesterday was the tenth. Till we get to the meridian of 180°"—and then, with a start, I broke off suddenly.

"What's the matter?" Martin cried, for he saw at once I was faltering and hesitating. "Ah, you see I was right now. You see this morning's the tenth, don't you?"

In a moment the truth flashed across me with a burst. I saw it all; the only wonder was how on earth I had failed so long to perceive it. I seized the poor lad's hand in a fervor of delight, relief and exultation.

"Martin," I cried, overjoyed, "we are both of us right in our own way of reckoning. This morning's the eleventh on board the Albatross here, but it's the tenth, I don't doubt, in your island at Tanaki!"

"What do you mean?" he cried, astonished, and gazing at me as if he thought me rather more than half-mad. "How on earth can it be Thursday here, while it's Wednesday at Tanaki?"

"Hold on a bit, youngster," said I, jumping out of my cabin, "till I've consulted the chart and made quite sure about it. Let me see. Here we are. Duke of Cumberland's Islands, 179° west. Hooray! Hooray!" I waved the chart round my head in triumph. "Jim, Jim!" I shouted out, rushing up the companion-ladder in my night-shirt as I stood; "here's a hope indeed! Here's splendid news. Put on all steam at once and we may save them yet. Tanaki's the other side of 180!"

Jim looked at me in astonishment.

"Why, what on earth do you mean, Julian?" he asked. "What on earth has that to do with our chance of saving them?"

"Jim," I cried once more, hardly knowing how to contain myself with excitement and reaction; "was there ever such a precious pair of fools in the world before as you and me, my good fellow? It's Wednesday morning in Tanaki, man! It's Wednesday in Tanaki! Tanaki's the other side of 180!"

As I said the words, Jim jumped at me like a wild creature and grasped my hand hard. Then he caught Martin in his arms and hugged him as tight as if he'd been his own father. After that he threw his cap up in the air and shouted aloud with delight. And when he'd quite finished all those remarkable performances, he looked hard into my face and burst out laughing.

"Well, upon my soul, Julian," he said, "for a couple of seasoned old Pacific travelers, I do agree with you that a pair of bigger fools and stupider dolts than you and I never sailed the ocean!"

"If it had been our first voyage across now," I said to Jim, feeling thoroughly ashamed of myself for my silly mistake, "there might have been some excuse for us!"

"Or if the boy hadn't told us there was a discrepancy in the accounts the very first day he ever came aboard," he added solemnly.

"But as it is," I went on, "such a scholar's mate, such a beginner's blunder as this is for two seafaring men—why, it's absolutely inexcusable!"

"Absolutely inexcusable!" Jim repeated, penitently.

"But if we clap on all steam we may get there yet on Wednesday morning," I continued, consulting my watch.

"By three or four o'clock on Wednesday morning," Jim echoed, examining the chart once more, and carefully noting the ship's position. "Why, it's Wednesday now, Julian. We've crossed 180°."

"But what day was yesterday?" Martin asked, all trembling.

"Why, yesterday," I answered, "was Wednesday the tenth, my boy; but to-day is Wednesday the tenth also. It comes twice over at this longitude. We've gained a day; that's the long and the short of it. We ought to have known it, my brother and I, who are such old hands at cruising in and out of the islands; but our anxiety and distress made us clean forget it."

"How does that come about?" Martin asked bewildered, his lips white as death.

"Just like this," said I. "Sailing one way, you see, from England, you sail with the sun; and sailing the other way, you sail against it. In one direction you keep gaining time, and in the other you lose it."

"The meridian of 180° is the particular place where the two modes of reckoning reach their climax," I hastened to add. "So, when you get to 180°, sailing west, you lose a day, and Saturday's followed right off by Monday. But sailing east, you gain a day, and have two Sundays running, or whatever else the day may be when you happen to get there. Now, we're going in the right direction for gaining a day; and so, though yesterday was Wednesday the tenth the other side of 180°, to-day's Wednesday the tenth, don't you see, this side of it? And as Tanaki's this side, your people must always have reckoned by the American day, so to speak, while we've reckoned all along by the Australian one. It's this morning those savages threatened to kill your father and mother, and if we make a good run, we shall still perhaps be in time to save them."

As I spoke, the boy's knees trembled under him with excitement. He staggered so that he caught at a rope for support. He was too much in earnest to cry, but the tears stood still in his eyes without falling.

"Oh! I hope to Heaven we'll be in time," he answered. "We may save them! We may save them!"

I went below and turned in once more for a little sleep, for I knew I should be wanted later in the morning; and having fortunately the true sailor's habit in that matter of dozing off whenever occasion occurred, I was soon snoring away again most comfortably on my pillow. At half-past three, Tom Blake came down once more to wake me.

"Land in sight, sir," he said, "on our starboard bow, and this young fellow Martin says he makes it out to be the north point of Tanaki."

In a minute I was on deck again, and peering at the dim land through the gray mist of morning—the same gray mist through which, as we afterwards learned, the poor creatures in the heathen temple saw the dawn break of the day that was to end their earthly troubles. It was Tanaki, no doubt, for Martin was quite sure he could recognize the headlands and the barrier reef. Our only question now was how next to proceed. We held a brief little council of war on deck, with Martin as our chief adviser on the local situation.

From what he told us, I came rapidly to the conclusion that it would be useless to attempt an open entrance into the little harbor of Makilolo, where the Chief had his hut, and where the mission-people, as we believed, were still confined in the temple. To do so would only be to arouse the anger of the savages beforehand; and unless we could get them well between a cross fire, and so effectually prevent any further outrage, we feared they might massacre the unhappy people in their hands the moment we hove in sight to enter the harbor. But here our friend Martin's local knowledge of the archipelago helped us out of our difficulty. He could pilot us, he said, to a retired bay at the back of the island, by the east side, where we could land a small party in boats, well armed with Sniders and our Winchester repeater; and Jack, who had slept all night, and was therefore the fresher of the two, would show us a path through the thick tropical underbrush by which we could approach the village from the rear, while the Albatross ran round again with the remainder of the crew, and brought our brass thirty-pounder to bear upon the savages from the open harbor.

This plan was at once received with universal approbation, and we proceeded forthwith to put it into execution.

Steering cautiously round the island, under cover of the mist, and fortunately unperceived by the assembled natives, who were too much occupied with their sing-sing to be engaged in scanning the offing, we reached at last the little retired bay of which Martin had spoken, and got ready our boat to land our military party. It was ticklish work, for we could afford to land only ten, all told, with Jack for our guide; but each man was armed with a good rifle and ammunition, and the habit of discipline made our little band, we believed, more than a match for those untutored savages. Nassaline, also, joined the military party, while seven men were left as a naval reserve. Silently and cautiously we landed on the white sandy beach, and turned with Jack into the thick tangled brake of tropical brushwood.

Meanwhile, my brother Jim, with Martin to guide him, undertook to take the Albatross round to the regular harbor; for Martin fortunately knew every twist and turn of those tortuous reef-channels, having been accustomed to navigate them from his childhood upwards, both in the mission-boat and in the native canoes which frequently put to sea for the bÊche-de-mer fishery.

Our plan of action, as arranged beforehand, was for the military party to wait about in the woods at the back of the village till the Albatross hove in sight off the mouth of the harbor. Then, the moment she appeared, she was to fire a blank shot towards the Chief's hut with her thirty-pounder; and at the same moment, we of the surprise party were to fall upon the savages, and before they could recover from their first surprise, demand the instant restitution of the missionary and his family.

Everything depended now upon the two boys. If Jack failed to show us the path aright—if Martin drove the Albatross upon reef or rock—all would be up with us, and the savages would massacre our whole party in cold blood, as they proposed to do with Macglashin and his little ones. I trembled to think on how slender a thread those four precious human lives depended. After all, they were but lads, mere children almost, and the rash confidence of youth might easily deceive them. But I decided, none the less, to trust to their instincts and their keen affection for their friends to see us through in our need. If that wouldn't lead us right, I felt sure in my own soul no human aid could possibly save the unhappy prisoners.
