I received General Meigs's order under which this ship came into our hands on Friday. She was then at Alexandria, and could not be got over the shoals to Washington. It was not till near night that I was able to get a lighter, and this, after one trip, was taken off to carry reinforcements to McDowell at Fredericksburg. I succeeded before daylight of Saturday in getting a tug at work, and by the next morning, Sunday, had her hold full. At eleven o'clock got the hospital company on board, but the commissaries failed in their engagements, and at last I had to send off a foraging-party at Alexandria for beef. Finally at four o'clock, D., who had gone after E., and E., who had gone after beef, arrived simultaneously from different directions. With E. came the beef, and we at once got under way. We had six medical students, twenty men nurses (volunteers all), four surgeons, four ladies, a dozen contrabands (field hands), three carpenters, and half a dozen miscellaneous passengers. There were, besides, five of us members of the Sanitary Commission and of the central staff, with one of the Philadelphia associates, eight military officers, ninety soldiers (convalescents, returning to their regiments), some quartermaster's mechanics, and a short ship's crew and officers. The ship has a house aft, with state-rooms for thirty, and an old-fashioned packet-saloon below, with state-rooms opening out of it; and all forward of the engine-rooms, a big steerage, or "'tween decks," which had been fitted with shelves, some of them fifteen feet deep, in which the soldiers had been carried to the Peninsula, packed in layers. I organized all our Commission people at sunset on Sunday, in two watches, sea-fashion; appointed watch-officers, and have worked since, night and day, refitting ship. We broke up all the transport arrangements,—they were in a filthy condition,—thoroughly scraped, washed, and scrubbed the whole ship from stem to stern, inside and out; whitewashed the steerage; knocked away the bulkheads of the wings of the engine-room section, so as to get a thorough draft from stem to stern; then set to fitting and furnishing new bunks; started a new house on deck, forward; made and fitted an apothecary's shop; and when we arrived at Cheeseman's Creek were ready for patients. * * * * * (M.) It was a bright day, the river peaceful and shining. Just as we started, the little gunboat _Yankee_ passed up, bringing, all on a string, five rebel craft which she had just taken in the Rappahannock. Late in the afternoon we passed the "stone fleet," eight boats, all ready to sink in the channel, in case the _Merrimack_ should try to run up the Potomac. The rebels having taken up all the buoys, at dark we had to come to anchor.
