Mr. Seward's speech, which was also received with frantic enthusiasm, sounded equally well. He said: "I trust that this glorious spectacle will make a deep impression upon all present, notwithstanding the fact that I am still convinced that peace may yet put an end to this unhappy conflict by means of a convention of all the States on the Fourth of July, 2776, which I have always advocated. As the President has remarked, the breeze which has just arisen in the bay of Naples, causes the Star-Spangled Banner to arouse a far prouder feeling in every American breast, than if a vessel should come in with a palmetto flag at her peak, and upon being asked where it came from, should reply: 'Oh, from one of the petty republics of America.' I have nothing more to say." I know this report is correct, for I copied both the speeches from a phonographic reporter's copy, and the phonographic reporter had only taken six glasses of old peach and honey before he went to work. Yours, hastily, ORPHEUS C. KERR. LETTER VI. INTRODUCING THE MACKEREL BRIGADE, DILATING ON HAVELOCKS AS FIRST MADE BY THE WOMEN OF AMERICA, ILLUSTRATING THE STRENGTH OF HABIT AND WEAKNESS OF "SHODDY," AND SHOWING HOW OUR CORRESPONDENT INDULGED IN A HUGE CANARD, AFTER THE MANNER OF AN ENLIGHTENED DAILY PRESS. WASHINGTON, D.C., June 15th, 1861. The members of the Mackerel Brigade, now stationed on Arlington Heights to watch the movements of the Potomac, which is expected to rise shortly, desire me to thank the women of America for supplies of Havelocks and other delicacies of the season just received. The Havelocks, my boy, are rather roomy, and we took them for shirts at first; and the shirts are so narrow-minded, that we took them for Havelocks. If the women of America could manage to get a little less linen in the collars of the latter article, and a little more into the other departments of the graceful garment, there would be fewer colds in this division of the Grand Army. The Havelocks, as I have said before, are roomy--very roomy, my boy. Villiam Brown, of Company 3, Regiment 5, put one on last night, when he went on sentry-duty, and looked like a broomstick in a pillow-case, for all the world. When the officer of the night came round and caught sight of Villiam in his Havelock, he was struck dumb with admiration for a moment. Then he ejaculated: "What a splendid moonbeam!" Villiam made a movement, and the sergeant came up. "What's that white object?" says the officer to the sergeant. "The young man which is Villiam Brown," says the sergeant. "Thunder!" roars the officer, "tell him to go to his tent, and take off that night-gown!" "You're mistaken," says the sergeant. "The sentry is Villiam Brown, in his Havelock, which was made by the wimmen of America." The officer was so justly exasperated at his mistake, that he went immediately to his head-quarters, and took the Oath three times running, with a little sugar.
