If tired Nature's sweet restorer, balmy Sleep, should ever take it into her head to invade our distracted country, she would meet with less resistance in Washington than it is possible for the able-bodied mind to comprehend. Notwithstanding the fact that President Lincoln is an honest man, my boy, the genius of Slumber has opened a large wholesale establishment here, and the tendency to repose is so general that the authorities are just able to wink at secession sympathizers. It takes so long to get the news of the war from New York, that our citizens grow languid in the intervals. On Monday, indeed, an enterprising chap from Nantucket opened a Museum on the outskirts of the town, by way of varying the monotony, and quite a numerous crowd assembled to witness the performance. This Museum comprises a real two shilling piece, inclosed in a strong glass case, to preserve it from the violence of the mob, and even respectable old married men go to see it, for the sake of past associations. On the occasion of my visit to this unique establishment I arrived shortly before the exhibition began, and found a brilliant array of beauty and fashion for an audience. It was quite interesting, my boy, to hear the conversation going on. There was a fine young chap just in front of me who has recently been appointed to the staff of the Commander-in-Chief in consequence of his great experience in the coal business, and says he to another Lubin's Extracts chap: "Fwedwick, who is that wavishing creatchah ovah they-ar, with the Peach-Orchard eyes and Lehigh hair?" "Aw, dimmy," says Lubin's Extracts, "that's the great heiress. She's worth eighty thousand postage-stamps." "The wed kind?" says the young staff-chap, eagerly--"is it the sticky wed kind, Fwed?" "No," says Lubin's Extracts, scornfully; "it's the green ten cent kind." "Intwojoose me," says the staff-chap, excitedly--"intwojoose me, Fwed; I must know her--upon my soul I must." Upon his soul, my boy--he said upon his _soul_! When it is possible for an introduction to take place upon such a soul as that, my boy, it will be comparatively able to manoeuvre an elephant brigade on the extreme point of an infant needle. When the manager of the Museum came out to lecture upon his great natural curiosity, there was immediate silence; and when the case was uncovered, revealing the quarter to full view, several very old gentlemen fainted! Alas! they remembered the time when--but no matter now--no matter now. "Ladies and gentlemen," says the manager, pointing solemnly to his treasure, "the rare and beautiful coin which you now behold was well known to our forefathers, who stamped the figure of Liberty upon it, in order to show the world that this is the only country where man is at Liberty to deal in slaves by way of financial speculation. This rare coin disappeared as soon as the Liberty I speak of seemed to be endangered, nor will it reappear in this country again while there are so many brokers ahead."
