It was a glorious morning, with a clear, brilliantly blue, cloudless sky overhead, out of which the sun, though only an hour high, already blazed with an ardour that gave promise of a scorching day; the sea was oil-smooth, with a glittering sheen like that of quicksilver in the wake of the sun, while away to the westward of us it flashed and gleamed in hues of the softest, purest, opalescent blue to the side of the ship with the running of the swell. There was not a breath of wind, nor the remotest sign of any; so I ordered the lighter canvas and the courses to be hauled down and clewed up, to save them from thrashing themselves to rags; and, having revelled in the luxury of a shower-bath of cool, sparkling brine from the hose, left the ship under the topsails and fore-topmast staysail, and went below to dress for breakfast. The calm that had now fallen upon us lasted unbroken for five full days, during which we sweltered, day and night, in the melting heat of the tropics, with the blazing sun right overhead every day at noon, and a waning moon soaring into the heavens later and still later each night to render the hours of darkness magical with the witchery of her beauty and mystery. And during the whole of this time we never shifted our position by so much as a single mile a day. At length, however, on the sixth day, a few cat's-paws came playing at intervals over the surface of the glass-smooth water, momentarily ruffling it into little evanescent patches of tender blue, and causing a transient ripple to play over the stagnant cloths of our canvas. As the day wore on the cat's-paws increased in frequency, in area, and in strength; and shortly before sundown a gentle, dainty little air of wind came stealing softly up from the eastward, to woo which we joyfully spread every rag of canvas we could show to it: and oh! how ineffably pleasant and delightful was the sound of the first faint liquid tinkling ripple that broke from our cutwater, and gushed gently past the bends in a stream of tiny bursting air-bells, as the beautifully moulded hull yielded to the faint impulse of the soft breathing and began to move under it with the languorous motion of a sleeping swan! Then, as the soft, warm, star-spangled darkness of the tropics closed down upon us and wrapped us within its impalpable folds, the breeze gathered strength and weight by imperceptible degrees, until the scarcely audible tinkle under the bows merged into the sound of a knife shearing through a tautly stretched silken web, with a musical fountain-like plashing at the cutwater and a crisp, gushing curl of the glassy wave under the lee bow as it broke and hurried past into our wake in a lacework of creamy swirling froth, gemmed with countless glittering foam-bubbles; while the log told us that the ship was slipping her way through the small wrinklings of the brine at a speed of fully six knots in the hour.
