We paused for a while, and looked at one another's faces blankly.
"Suppose," Jim suggested at last, "we get out the charts and see if such a place as Tanaki is marked upon them anywhere."
"Right you are," says I. "Overhaul your maps, and when found, make a note of."
Well, we did overhaul them for an hour at a stretch, and searched them thoroughly, inch by inch, Jim taking one sheet of the Admiralty chart for the South Pacific, and I the other; but never a name could we find remotely resembling the sound or look of Tanaki. Tom Blake, too, was positive, as he put it himself, that "there weren't no such name, not in the whole thunderin' Pacific, nowheres." So after long and patient search we gave up the quest, and determined to wait for further particulars till the boys had recovered enough to tell us their strange story.
Meanwhile, it was clear we must steer somewhere. We couldn't go beating wildly up and down the Pacific, on the hunt for a possibly non-existent Tanaki, allowing the Albatross to drift at her own sweet will wherever she liked, pending the boys' restoration to speech and health. So the question arose what direction we should steer in. Jim solved that problem as easy as if it had come out of the first book of Euclid (he was always a mathematician, Jim was, while for my part, when I was a little chap at school, the asses' bridge at an early stage effectually blocked my further progress. I could never get over it, even with the persuasive aid of what Dr. Slasher used politely to call his vis a tergo.)
"They're too weak to row far, these lads," Jim said in his didactic way—ought to have been a schoolmaster or a public demonstrator, Jim: such a head for proving things! "Therefore they must mostly have been drifting before the wind ever since they started. Now, wind for the last fortnight's been steadily nor'east"—the anti-trade was blowing. "Therefore, they must have come from the nor'east, I take it; and if we steer clean in the face of the wind, we're bound sooner or later to arrive at Tanaki."
"Jim," said I, admiring him, like, "you're really a wonderful chap. You do put your finger down so pat on things! Steer to the nor'-east it is, of course. But I wonder how far off Tanaki lies, and what chance we've got of reaching there by Wednesday the tenth?" For though we didn't even know yet who the people were who were threatened with massacre at this supposed Tanaki, we couldn't let them have their throats cut in cold blood without at least an attempt to arrive there in time to prevent it.
Of course, we knew with our one brass gun we should be more than a match for any Melanesian islanders we were likely to meet with, if once we could get there; but the trouble was, should we reach in time to forestall the massacre?
By Wednesday the tenth we must reach Tanaki—wherever that might be.
Jim took out a piece of paper and totted up a few figures carelessly on the back. "We've plenty of coal," he said, "and I reckon we can make nine knots an hour, if it comes to a push, even against this head wind. To-day's the sixth; that gives us four clear days still to the good. At nine knots, we can do a run of two hundred and thirty-six knots a day. Four two-hundred-and-thirty-sixes is nine hundred and forty-four, isn't it? Let me see; four sixes is twenty-four; put down four and carry two: four three's is twelve, and two's fourteen: four two's—yes, that's all right: nine hundred and forty-four, you see, ex-actly. Well, then, look here, Julian: unless Tanaki's further off than nine hundred and forty-four nautical miles—which isn't likely—we ought to get there by twelve o'clock on Wednesday at latest. Nine hundred and forty-four miles is an awful long stretch for two boys to come in an open boat. I don't expect these boys can have done as much as that or anything like it."
