Read it through once

It was six o'clock on a hot summer morning. The 'Pennsylvania' was creeping along, north of Ship Island, about sixty miles below Memphis on a half-head of steam, towing a wood-flat which was fast being emptied. George Ealer was in the pilot-house-alone, I think; the second engineer and a striker had the watch in the engine room; the second mate had the watch on deck; George Black, Mr. Wood, and my brother, clerks, were asleep, as were also Brown and the head engineer, the carpenter, the chief mate, and one striker; Captain Klinefelter was in the barber's chair, and the barber was preparing to shave him. There were a good many cabin passengers aboard, and three or four hundred deck passengers--so it was said at the time--and not very many of them were astir. The wood being nearly all out of the flat now, Ealer rang to 'come ahead' full steam, and the next moment four of the eight boilers exploded with a thunderous crash, and the whole forward third of the boat was hoisted toward the sky! The main part of the mass, with the chimneys, dropped upon the boat again, a mountain of riddled and chaotic rubbish--and then, after a little, fire broke out.
