The Trade-Wind

“No use bothering about St. Paul Rocks or the Rocas, Angel,” said he. “They rise out o’ the deep sea, and if we’re to hit, soundings won’t warn us in time. I take it we’ll pass between them and well north of Ascension.” So he checked in the yards a little and brought the wind more abeam.
One day Yank Tate appeared at the captain’s elbow, and suggested, in a low voice, that he examine the treasure-chests in the ‘tween-deck. “I was down stowing away some oakum,” he said, “an’ I was sure I heard the lid close; but nobody answered me, an’ I couldn’t feel anybody.”
Captain Swarth descended to his cabin and found his keys missing; then he and the carpenter visited the chests. They were locked tight, and as heavy as ever.
“Some one has the keys, Yank, and has very likely raided the diamonds. We can’t do anything but wait. He can’t get away. Keep still about it.”
The air became cooler as they sailed on; and judging that the trade-wind was blowing more from the south than he had allowed for, the captain brought the wind squarely abeam, and the brig sailed faster. Still, it was too cool for the latitude, and it puzzled him, until a man came aft and groaned that he had lifted his bandage to bathe his eyes, and had unmistakably seen the sun four points off the port quarter; but his eyes were worse now, and he could not do it again.
“Four points off!” exclaimed Swarth. “Four o’clock in the afternoon. That’s just about where the sun ought to be heading due east, and far enough south o’ the line to bring this cool weather. We’re not far from Ascension. Never knew the sou’east trade to act like this before. Must ha’ been blowing out o’ the sou’west half the time.”
A week later they were hove to on the port tack under double-reefed topsails, with a cold gale of wind screaming through the rigging and cold green seas boarding their weather bow. It was the first break in the friendly trade-wind, and Swarth confessed to himself–though not to his men–that he was out of his reckoning; but one thing he was sure of–that this was a cyclone with a dangerous center.
The brig labored heavily during the lulls as the seas rose, and when the squalls came, flattening them to a level, she would lie down like a tired animal, while the aeolian song aloft prevented orders being heard unless shouted near by. Captain Swarth went below and smashed the glass of an aneroid barometer (newly invented and lately acquired from an outward-bound Englishman), in which he had not much confidence, but which might tell him roughly of the air-density. Feeling of the indicator, and judging by the angle it made with the center,–marked by a ring at the top,–he found a measurement which startled him. Setting the adjustable hand over the indicator for future reference, he returned to the deck, ill at ease, and ordered the topsails goose-winged. By the time the drenched and despairing blind men had accomplished this, a further lowering of the barometer induced him to furl topsails and foretopmast-staysail, and allow the brig to ride under a storm-spanker. Then the increasing wind required that this also should be taken in, and its place filled by a tarpaulin lashed to the weather main-rigging.
“Angel,” said the captain, shouting into the mate’s ear, “there’s only one thing to account for this. We’re on the right tack for the Southern Ocean; but the storm-center is overtaking us faster than we can drift away from it. We must scud out of its way.”
So they took in the tarpaulin and set the foretopmast-staysail again, and, with the best two helmsmen at the wheel, they sped before the tempest for four hours, during which there was no increase of the wind and no change in the barometer; it still remained at its lowest reading.
