The best method of running an oval frame, 18 in. by 14in., in Keene's cement, would be to use trammels and zinc templates, as shown in the figure, which is drawn proportionate to the required size; or the frame might be made of wood and bent to the required shape; or a series of divisions might be made on the oval by drawing lines perpendicular to the curve (as shown on the diagram) and cutting similar pieces from a straight strip of moulding and joining these together, though this would be a somewhat elaborate method.
