At early dawn of Monday the 22d, after feeling along slowly all night, we see the harbor of Annapolis. A frigate with sails unbent lies at anchor. She flies the stars and stripes. Hurrah!

A large steamboat is aground farther in. As soon as we can see anything, we catch the glitter of bayonets on board.

By-and-by boats come off, and we get news that the steamer is the "Maryland," a ferry-boat of the Philadelphia and Baltimore Railroad. The Massachusetts Eighth Regiment had been just in time to seize her on the north side of the Chesapeake. They learned that she was to be carried off by the crew and leave them blockaded. So they shot their Zouaves ahead as skirmishers. The fine fellows rattled on board, and before the steamboat had time to take a turn or open a valve, she was held by Massachusetts in trust for Uncle Sam. Hurrah for the most important prize thus far in the war! It probably saved the "Constitution," "Old Ironsides," from capture by the traitors. It probably saved Annapolis, and kept Maryland open without bloodshed.

As soon as the Massachusetts Regiment had made prize of the ferry-boat, a call was made for engineers to run her. Some twenty men at once stepped to the front. We of the New York Seventh afterwards concluded that whatever was needed in the way of skill or handicraft could be found among those brother Yankees. They were the men to make armies of. They could tailor for themselves, shoe themselves, do their own blacksmithing, gunsmithing, and all other work that calls for sturdy arms and nimble fingers. In fact, I have such profound confidence in the universal accomplishment of the Massachusetts Eighth, that I have no doubt, if the order were, "Poets to the front!" "Painters present arms!" "Sculptors charge bagonets!" a baker's dozen out of every company would respond.

Well, to go on with their story,—when they had taken their prize, they drove her straight down-stream to Annapolis, the nearest point to Washington. There they found the Naval Academy in danger of attack, and Old Ironsides—serving as a practice-ship for the future midshipmen—also exposed. The call was now for seamen to man the old craft and save her from a worse enemy than her prototype met in the "Guerrière." Seamen? Of course! They were Marblehead men, Gloucester men, Beverly men, seamen all, par excellence! They clapped on the frigate to aid the middies, and by-and-by started her out into the stream. In doing this their own pilot took the chance to run them purposely on a shoal in the intricate channel. A great error of judgment on his part! as he perceived, when he found himself in irons and in confinement. "The days of trifling with traitors are over!" think the Eighth Regiment of Massachusetts.

But there they were, hard and fast on the shoal, when we came up. Nothing to nibble on but knobs of anthracite. Nothing to sleep on softer or cleaner than coal-dust. Nothing to drink but the brackish water under their keel. "Rather rough!" as they afterward patiently told us.

Meantime the Constitution had got hold of a tug, and was making her way to an anchorage where her guns commanded everything and everybody. Good and true men chuckled greatly over this. The stars and stripes also were still up at the fort at the Naval Academy.

Our dread, that, while we were off at sea, some great and perhaps fatal harm had been suffered, was greatly lightened by these good omens. If Annapolis was safe, why not Washington safe also? If treachery had got head at the capital, would not treachery have reached out its hand and snatched this doorway? These were our speculations as we began to discern objects, before we heard news.

But news came presently. Boats pulled off to us. Our officers were put into communication with the shore. The scanty facts of our position became known from man to man. We privates have greatly the advantage in battling with the doubt of such a time. We know that we have nothing to do with rumors. Orders are what we go by. And orders are Facts.

We lay a long, lingering day, off Annapolis. The air was full of doubt, and we were eager to be let loose. All this while the Maryland stuck fast on the bar. We could see them, half a mile off, making every effort to lighten her. The soldiers tramped forward and aft, danced on her decks, shot overboard a heavy baggage-truck. We saw them start the truck for the stern with a cheer. It crashed down. One end stuck in the mud. The other fell back and rested on the boat. They went at it with axes, and presently it was clear.
