April Fool.--Some mischievous fellow has been playing the fool with the Emporium, by representing that the Steam Boat building at this place is of such length that she cannot be taken through the Harbor Lock. This important piece of news was received by the editors on the first day of this month, whose honest unsuspecting natures suffered them to seize the bait. It is to presumed, however, that for the future they will be more upon their guard, as many waggeries are usually committed on the first days of April.

The truth is, there are two Steam Boats now building, and in a great state of forwardness, at this place, the largest of which was never intended to pass though the lock, but was designed for Lake Erie. The smaller boat will ply between Black Rock and Niagara Falls, and is constructed in such a manner as to admit her through the lock without difficulty.
