Fall of a Wall.
--The new wall of an extensive flour warehouse, Nos. 36 and 38 Whitehall street, New York, fell to the ground Wednesday morning. A portion of the building fronting on Pearl street was filled with flour, the pressure of which was so great on the walls, insecurely built, that the structure gave way. Twelve thousand barrels of flour were on storage at the time of the accident.--The loss of property is estimated at $30,000. R. T. Johnson, the owner of the building, was arrested on the charge of erecting an unsafe building.
