Cellar cross-wall, joist, tenon, wall plates detail

Digital photograph showing detail view of the masonry partition wall between the ground-level DeTurk kitchen and root cellar at its intersection with the exterior doorway frame in the east eaves wall. The timber in the upper right segment of the photo is a floor joist bearing on the partition wall and the stacked pair of wall plates ["relieving lintels," seen in the left-center of the photo]. The square-cut end-grain visible at the eastern [left] end of the joist is the through-tenon from the header which anchors the southern outlooker [cantilevered support] for the exterior doorway hood [see DTR09PH121--1001.01.217 for a view of the underside of the header after removal of the top end-blocks of the cross-wall]. The tenon is cut flush to the northern face of the joist at its emergence through the mortise {1}.
