The Tongue and Groove.—This form of uniting members has only a limited application. It is serviceable for floors, table tops, paneling, etc. In Fig. 213, a door panel is shown, and the door mullions (B) are also so secured to the rail (C). The tongue-and-groove method is never used by itself. It must always have some support or reinforcing means.

Beading.—This part of the work pertains to surface finishings, and may or may not be used in connection with rabbeting.
Figs. 214 and 215 show the simplest and most generally adopted forms in which it is made and used in connection with rabbeting, or with the tongue and groove. The bead is placed on one or both sides of that margin of the board (Fig. 214) which has the tongue, and the adjoining board has the usual flooring groove to butt against and receive the tongue. It is frequently the case that a blind bead, as in Fig. 215, runs through the middle of the board, so as to give the appearance of narrow strips when used for wainscoting, or for ceilings. The beads also serve to hide the joints of the boards.

Ornamental Bead Finish.—These figures show how the bead may be used for finishing corners, edges and projections. Fig. 216 has a bead at each corner of a stile (A), and a finishing strip of half-round material (B) is nailed to the flat edge. Fig. 217 has simply the corners themselves beaded, and it makes a most serviceable finish for the edges of projecting members.
Fig. 218, used for wider members, has the corners beaded and a fancy molding (C); or the reduced edge of the stile itself is rounded off.
