412. When a post or strut is required to be longer than timber can be procured, which sometimes may occur, the same form of joint or scarf is applicable as when the piece is pulled in the direction of its length, with this difference, that there must not be any inclined or oblique parts in the scarf.

Figs. 127,129,130, 134,135, and 139, will answer equally well for posts or ties, except that it would be better to tongue the ends as at e, Fig. 139.

In Fig. 125 a piece on each of the four sides would be necessary, unless some other mode of strengthening it could be applied in the arrangement of the framing. It is not a very neat method of splicing a strut, but it is a very convenient one, especially in temporary structures, such as centres, where it may generally be braced in one direction, and where a more elaborate form of joining would be out of place.
