The "saddle joint" ([Fig. 351]) is used for connecting upright posts to heads or sills of framing, and undoubtedly takes its name from its similarity to the way in which the saddle fits the horse. It does not weaken the framing as does a mortise and tenon joint, and shrinkage has little effect upon the joint. The "cogged joint," used for connecting purlins to rafter and joists to girders, is illustrated in [Fig. 353].

Birdsmouth Joints.—[Fig. 354] is a "birdsmouth joint," a simple joint which can be readily made by the handsaw, used when a spar fits on the wall plate. A nail is shown securing it in position.
[Fig. 355] shows the birdsmouth joint where the spar runs over the outside of the wall plate, thus allowing a fixing for an ornamental finish.
