Span, 7 feet 2 inches. Field, Hinchman & Smith, Architects.

    This work was guaranteed to hold a live load of 800 pounds per square foot. Part of the panel shown was loaded with 40,000 pounds of loose sand, held in place by tiers of boxes without bottoms. Not even a hair crack developed with this load, which remained on twenty-four hours with a deflection of 3/16 inch. Deflection fully recovered after removal of load.
