At a corner in log cabin construction, a rounded notch cut near one end in the lower surface of a horizontal log; forms an interlocking joint when mated with a similarly notched log set at a right angle to it. Occasionally, this term is also used for a double-saddle notch, which is cut in both sides of a round log; in such instances, the logs at right angles are unnotched.
