The engraving of the "Inauguration of George Washington" appealed to the patriotic feeling of every American. What friend of his country would refuse to part with the paltry sum of one dollar, which would enable him to possess this transcendent work of art, copied from the "celebrated painting" of the no less celebrated "David Paul Laurens;" a blood relation, no doubt, of the departed "Van Denton." Each ticket was so embellished with intimations of the rich gifts possibly in store for its holder, as almost to make him feel as if he were already driving a "blood horse," or taking his ease in the "magnificent residence on the Hudson." The reader is by this time probably aware of the true character of "Dashall & Co.," and their magnificent scheme. The former were atrocious impostors, and the latter was only a bag of wind. The suspicions of the New York post master were excited as to the character and destination of the numerous letters which came addressed to the aforesaid firm; and the Chief of the Police taking the matter in hand, a detachment from that body made a descent on 486 Broadway, where they found a respectable female of Milesian extraction, engaged in washing the floor; and observed an open window, through which the representative of Dashall & Co. had probably made his exit. There was no furniture of any description in the room; so, having secured neither "persons" nor "papers," the civil authority was compelled to beat a retreat, not without sundry remonstrances from the old woman, touching the invasion of her "_clane flure_." She could tell them nothing about the firm, and only knew that she was sent there by the owner of the room to "clane up," which occupation she resumed, after imparting this information, with a vigor that threatened the immediate submersion of the intruders. The parties concerned in this fraudulent transaction are supposed to have cleared upwards of fifty thousand dollars by the operation, which, allowing for the per-centage to agents and other expenses, proves conclusively that there was more than that number of fools existing at the time in this enlightened land. We would hope that those who were taken in by this cheat, will not be thus deceived again. We trust that the foregoing record of knavery, whose contrivers were indebted, in some measure, for the carrying out of their plans, to the post masters who acted as agents, will have the effect of producing greater caution on the part of these officials as respects undertaking agencies for _unknown_ individuals. It would seem that a proper regard for the public interest would prevent any post master from lending himself, even undesignedly, to a fraudulent scheme like this of "Dashall & Co." It would be easy to refuse to have anything to do with proposed agencies, whose principals were not known to the post master, or concerning whom satisfactory information could not be obtained.
