It is worth noticing that the chief haunts of the city of New York, the Central Park, has thus far remained unviolated by the dirty hands of these vulgar advertisers. Without knowing anything about it, I have no doubt whatever that the commissioners have been approached often by parties desiring the privilege of advertising within its limits. Among the advertising fraternity it would be thought a gigantic opportunity to be able to flaunt the name of some bug-poison, fly-killer, bowel-rectifier, or disguised rum, along the walls of the Reservoir; upon the delicate stone-work of the Terrace, or the graceful lines of the Bow Bridge; to nail up a tin sign on every other tree, to stick one up right in front of every seat; to keep a gang of young wretches thrusting pamphlet or handbill into every person's palm that enters the gate, to paint a vulgar sign across every gray rock; to cut quack words in ditch-work in the smooth green turf of the mall or ball-ground. I have no doubt that it is the peremptory decision and clear good taste of the Commissioners alone, which have kept this last retreat of nature within our crowded city from being long ago plastered and daubed with placards, handbills, sign-boards and paint, from side to side and from end to end, over turf, tree, rock, wall, bridge, archway, building and all. CHAPTER III. MONSIEUR MANGIN, THE FRENCH HUMBUG. One of the most original, unique, and successful humbugs of the present day was the late Monsieur Mangin, the blacklead pencil maker of Paris. Few persons who have visited the French capital within the last ten or twelve years can have failed to have seen him, and once seen he was not to be forgotten.

He drove a pair of bay horses, attached to an open carriage with two seats, the back one always occupied by his valet. Sometimes he would take up his stand in the Champs Elysees; at other times, near the column in the Place Vendome; but usually he was seen in the afternoon in the Place de la Bastille, or the Place de la Madeleine. On Sundays, his favorite locality was the Place de la Bourse. Mangin was a well-formed, stately-looking individual, with a most self-satisfied countenance, which seemed to say: "I am master here; and all that my auditors have to do is, to listen and obey." Arriving at his destined stopping-place, his carriage halted. His servant handed him a case from which he took several large portraits of himself, which he hung prominently upon the sides of his carriage, and also placed in front of him a vase filled with medals bearing his likeness on one side and a description of his pencils on the other. He then leisurely commenced a change of costume. His round hat was displaced by a magnificent burnished helmet, mounted with rich plumes of various brilliant colors. His overcoat was laid
