a rapid change, and the water seemed more than usually transparent.  Although I could distinctly see the bottom, yet, heaving the lead, I found the ship in fifteen fathoms.  The air now became intolerably hot, and was loaded with spiral exhalations similar to those arising from heat iron.  As night came on, every breath of wind died away, an more entire calm it is impossible to conceive.  The flame of a candle burned upon the poop without the least perceptible motion, and a long hair, held between the finger and thumb, hung without the possibility of detecting a vibration.  However, as the captain said he could perceive no indication of danger, and as we were drifting in bodily to shore, he ordered the sails to be furled, and the anchor let go.  No watch was set, and the crew, consisting principally of Malays, stretched themselves deliberately upon deck.  I went below —­ not without a full presentiment of evil.  Indeed, every appearance warranted me in apprehending a Simoom.  I told the captain my fears; but he paid no attention to what I said, and left me without deigning to give a reply.  My uneasiness, however, prevented me from sleeping, and about midnight I went upon deck. —­ As I placed my foot upon the upper step of the companion-ladder, I was startled by a loud, humming noise, like that occasioned by the rapid revolution of a mill-wheel, and before I could ascertain its meaning, I found the ship quivering to its centre.  In the next instant, a wilderness of foam hurled us upon our beam-ends, and, rushing over us fore and aft, swept the entire decks from stem to stern.

The extreme fury of the blast proved, in a great measure, the salvation of the ship.  Although completely water-logged, yet, as her masts had gone by the board, she rose, after a minute, heavily from the sea, and, staggering awhile beneath the immense pressure of the tempest, finally righted.

By what miracle I escaped destruction, it is impossible to say.  Stunned by the shock of the water, I found myself, upon recovery, jammed in between the stern-post and rudder.  With great difficulty I gained my feet, and looking dizzily around, was, at first, struck with the idea of our being among breakers; so terrific, beyond the wildest imagination, was the whirlpool of mountainous and foaming ocean within which we were engulfed.  After a while, I heard the voice of an old Swede, who had shipped with us at the moment of our leaving port.  I hallooed to him with all my strength, and presently he came reeling aft.  We soon discovered that we were the sole survivors of the accident.  All on deck, with the exception of ourselves, had been swept overboard; —­ the captain and mates must have perished as they slept, for the cabins were deluged with water.  Without assistance, we could expect to do little for the security of the ship, and our exertions were at first paralyzed by the momentary expectation of going down.  Our cable had, of course, parted like pack-thread,
