Came a stretch of ocean that to Daughtry was like all other stretches of ocean and unidentifiable from them.  No land broke the sea-rim.  The ship the centre, the horizon was the invariable and eternal circle of the world.  The magnetic needle in the binnacle was the point on which the Mary Turner ever pivoted.  The sun rose in the undoubted east and set in the undoubted west, corrected and proved, of course, by declination, deviation, and variation; and the nightly march of the stars and constellations proceeded across the sky.

And in this stretch of ocean, lookouts were mastheaded at day-dawn and kept mastheaded until twilight of evening, when the Mary Turner was hove-to, to hold her position through the night.  As time went by, and the scent, according to the Ancient Mariner, grow hotter, all three of the investors in the adventure came to going aloft.  Grimshaw contented himself with standing on the main crosstrees.  Captain Doane climbed even higher, seating himself on the stump of the foremast with legs a-straddle of the butt of the fore-topmast.  And Simon Nishikanta tore himself away from his everlasting painting of all colour-delicacies of sea and sky such as are painted by seminary maidens, to be helped and hoisted up the ratlines of the mizzen rigging, the huge bulk of him, by two grinning, slim-waisted sailors, until they lashed him squarely on the crosstrees and left him to stare with eyes of golden desire, across the sun-washed sea through the finest pair of unredeemed binoculars that had ever been pledged in his pawnshops.

“Strange,” the Ancient Mariner would mutter, “strange, and most strange.  This is the very place.  There can be no mistake.  I’d have trusted that youngster of a third officer anywhere.  He was only eighteen, but he could navigate better than the captain.  Didn’t he fetch the atoll after eighteen days in the longboat?  No standard compasses, and you know what a small-boat horizon is, with a big sea, for a sextant.  He died, but the dying course he gave me held good, so that I fetched the atoll the very next day after I hove his body overboard.”

Captain Doane would shrug his shoulders and defiantly meet the mistrustful eyes of the Armenian Jew.

“It cannot have sunk, surely,” the Ancient Mariner would tactfully carry across the forbidding pause.  “The island was no mere shoal or reef.  The Lion’s Head was thirty-eight hundred and thirty-five feet.  I saw the captain and the third officer triangulate it.”

“I’ve raked and combed the sea,” Captain Doane would then break out, “and the teeth of my comb are not so wide apart as to let slip through a four-thousand-foot peak.”

“Strange, strange,” the Ancient Mariner would next mutter, half to his cogitating soul, half aloud to the treasure-seekers.  Then, with a sudden brightening, he would add: 

“But, of course, the variation has changed, Captain Doane.  Have you allowed for the change in variation for half a century!  That should make a grave difference.  Why, as I understand it, who am no navigator, the variation was not so definitely and accurately known in those days as now.”
