You have now left your three longer pieces of iron. One of these must be placed on the lower rear end of your right-hand side-wall (as you face the door) at seven and one half inches above the bottom, and with the elbow turned down. The other two go on opposite ends of the left-hand wall, that at the rear end turned down, and that in front turned up, the former seven and one half, the latter six inches above the bottom edge. But all these long ones must project three and one quarter inches, because they must reach past the edge of the adjoining wall, as you will see when you stand the walls up; the edge of the rear flush with face of the sidings, and lock them together, as shown in [fig. 9].
