Presently the man at the wheel startled me with an observation. I went to him, and he pointed upward with a long, shadowy arm. I looked, and saw a corposant, as it is called at sea,--a St. Elmo's fire,--burning at the end of the crossjack-yard. The yard lay square, and the polished sea beneath gave back the reflection so clearly that the mystic fire lay like a huge glow-worm on the black mirror. "There should be wind not far off," said the helmsman, in a subdued voice; for few sailors can see one of these lights without a stirring of their superstitious instincts, and this particular exhalation hung close to us. "I hope so," said I, "though I don't know where it's to come from." As I spoke, the light vanished. I ran my eye over the yards, expecting its reappearance; but it returned no more, and the sails rose pale and phantom-like to the stars. I was in an odd humour, and this was an apparition not to brighten one up. Of course one knows all about these maritime corpse-candles, and can explain their nature; but nevertheless the sudden kindling of them upon the darkness of the night, in the dead hush of the calm or amid the fury of the shrieking hurricane, produces feelings which there is nothing in science to resolve. I could have laughed to find myself sending a half-awed look aloft, as if I expected to see some visionary hand at work upon another one these graveyard illuminations-with a stealing out of some large, sad face to the melancholy glow; but I returned to the side very pensive for all that, and there stood watching the fiery outline of a shark subtly sneaking close to the surface (insomuch that the wake of its fin slipped away in little coils of green flame) toward the ship's bows. Half an hour later the dark curl of a light air of wind shattered the starlight in the sea, and our canvas fell asleep. I called to the watch to trim sail, and in a few moments the decks were busy with the figures of men pulling and hauling and surging out at the ropes in sulky, slumberous growlings. The captain arrived. "Little worth having in this, I fear," said he. "But make the most of it--make the most of it. Get the foretopmast stunsail run up. If she creeps but a league, it is a league to the good."
