61. The paneled wall lining for halls and stairways is made of various heights, the arrangement and treatment of the panels being varied to meet the ideas of the designer. In Fig. 57 is shown a portion of wainscoting as it passes from the hall up the flight. A vertical section of the framework panels and moldings as usually made, is shown at D, in which a is the baseboard; b, the bottom rail; c, the panels; d, the middle rail; c, the top rail; f, the cap molding; g, the base molding; and h, the furring strip. In the elevation, h' h' is a stile with a groove j to receive the return wainscoting; at k, k are muntins. The stile h' h' extends the whole height, and the three rails are framed into it. The panels are square on the level portion, but up the flight they become lower, as the width of the wainscot n n is less than the width m m. The curves at the junction of the pitch and level lines are described from three different centers, as shown. The curves cannot be described from a common center, as the two portions are not of the same width. By producing the tangents of the level and inclined portions of the top, bottom, and central rails, and deciding on the length of the curves, radial lines may be drawn from the points, as at c, c, thus locating the center, from which simple curves may be drawn. At (a) is shown a method of fastening the panels whereby no nails show on the face of the molding.
The panels are polished separately, and put in place after the frame and moldings are finished. The framework should be well seasoned, and the walls should be perfectly dry before the wainscoting is set in position.
