When a sail on the coast of Africa heaves in sight of _a slaver_, it is always best for the imperilled craft, especially if gifted with swift hull and spreading wings, to take flight without the courtesies that are usual in mercantile sea-life. At the present day, fighting is, of course, out of the question, and the valuable prize is abandoned by its valueless owners. At all times, however,--and as a guard against every risk, whether the cue be to fight or fly,--the prudent slaver, as soon as he finds himself in the neighborhood of unwholesome canvas, puts out his fire, nails his forecastle, sends his negroes below, and secures the gratings over his hatches. All these preparations were quietly made on board the Esperanza; and, in addition, I ordered a supply of small arms and ammunition on deck, where they were instantly covered with blankets. Every man was next stationed at his post, or where he might be most serviceable. The cannons were sponged and loaded with care; and, as I desired to deceive our new acquaintance, I ran up the Portuguese flag. The calm still continued as the day advanced;--indeed, I could not perceive a breath of air by our dog-vane, which veered from side to side as the schooner rolled slowly on the lazy swell. The stranger did not approach, nor did we advance. There we hung-- "A painted ship upon a painted ocean!" I cannot describe the fretful anxiety which vexes a mind under such circumstances. Slaves below; a blazing sun above; the boiling sea beneath; a withering air around; decks piled with materials of death; escape unlikely; a phantom in chase behind; the ocean like an unreachable eternity before; uncertainty every where; and, within your skull, a feverish mind, harassed by doubt and responsibility, yet almost craving for any act of desperation that will remove the spell. It is a living nightmare, from which the soul pants to be free. With torments like these, I paced the deck for half an hour beneath the awning, when, seizing a telescope and mounting the rigging, I took deliberate aim at the annoyer. He was full seven or eight miles away from us, but very soon I saw, or fancied I saw, a row of ports, which the Dane had not: then sweeping the horizon a little astern of the craft, I distinctly made out three boats, fully manned, making for us with ensigns flying. Anxious to avoid a panic, I descended leisurely, and ordered the sweeps to be spread once more in aid of the breeze, which, within the last ten minutes, had freshened enough to fan us along about a knot an hour. Next, I imparted my discovery to the officers; and, passing once more among the men to test their nerves, I said it was likely they would have to encounter an angrier customer than the Dane. In fact, I frankly told them our antagonist was unquestionably a British cruiser of ten or twelve guns, from whose clutches there was no escape, unless we repulsed the boats.
