He has also noticed that the Philadelphians are having a lively and brotherly dispute over their new public buildings; they don't know where to put them. Most of the citizens are very much opposed to doing any thing on the square; that is to say, Independence Square, where the citizens assert their freedom by treading down all the grass, and making a mud-flat of what was intended to be a turfy lawn. Some folks want the buildings on PENN Square--so called because it is split in the middle, and answers its intended purposes only on paper. But the good Quakers hate to interfere with the rights of the blacks, whether they be men or women, and so many of the latter make this square their abiding place every summer, that it would seem like a violation of the spirit of the Fifteenth Amendment to disturb them. But there is no doubt that the good Philadelphians will have their new buildings some day, for they are very enterprising. Witness the disposition of one of their leading men, "Slushy" SMITH by name, who wants fifty thousand dollars with which to open an avenue from the Delaware to Sixth street, basing his claims upon the fact that such avenue will lead to Fairmount Park! Now, as the nearest point of the park is two miles and a half from Sixth street, the vigor of the scheme and the foreseeing character of the projectors are worthy of a metropolis. PUNCHINELLO is furthermore delighted to see that a son of PENN has decided the great question of the Pope's infallibility, which so vexes our OEcumenical fellow-creatures. POPE has been beheaded at Harrisburg, and of course there is no further need to discuss his infallibility. When a man loses his head, he is fallible. To be sure, the case was only one of a picture of GRANT and his Generals, which hung in the State Library, and in which POPE'S head was painted out, and Governor GEARY'S substituted; but the act shows, on the part of the adherents of the leaden-legged governor, a head-strong determination to proceed to extremities which has given rise to the gravest apprehensions; but PUNCHINELLO hopes for the best. It is expected that the Legislature will soon compel the inhabitants of the City of Fraternites to send their children to school, whether they like it or not. This is certainly progression, and PUNCHINELLO now looks confidently forward to a law compelling all Philadelphians to wash their pavements twice a day; to have white marble front-steps (without railings) to all their houses; to build said houses entirely of red brick, with green shutters; to make their sidewalks of similar bricks, laid unevenly, to agitate passers-by and so prevent dyspepsia, and that each house shall have at least one little gutter running over its pavement. * * * * * "Lost at Sea."
