The entire length of this extraordinary foundation totaled 108 feet.
The northwest corner of Structure B was not excavated because it was hidden beneath a group of cedar trees which could not be disturbed. South of the trees, however, the section of the west-wall foundation was exposed to a length of 15.5 feet. This section was situated partly in, and partly north of, the north cellar area. The cross measurement, from outer edge to outer edge, was 28 feet, the same as the length of the south foundation wall. Another short section of the west foundation wall also was exposed from the southwest corner as far as a private driveway which limited the excavation.
Abutting the exterior of the north wall of the foundation a flagstone pavement was found, extending 8.45 feet northward and 16 feet westward from the northeast corner. Against the foundation, within this space, was a U-shaped brick wall, forming a hollow rectangle 5 feet by 3.6 feet (inside). The space was filled with ashes, loose bricks, and other refuse. This brickwork was the foundation for a small porch, the lime-sandstone slabs surrounding it having been an apron or a small terrace.
Extending westward from the cedar trees, beyond the projected 28-foot length of the north wall, was a short section of brick wall foundation, the outer surface of which was faced with slabs of red sandstone and dressed on the top with a cyma-reversa molding. The tops of the slabs were rough, but each had slots and channels for receiving iron tie bars (ill. 3) that were still in place. This wall was inset four inches to the south of the alignment of the main north foundation wall.

To the left of top of sign, molded red-sandstone trim can be seen which apparently surrounded the piazza. Bricks in front of trim appear to have been added later as step foundation. Brick buttressing of main-foundation footing appears at right.]
The northwest corner of this additional structure was hidden under the highway. Even now, however, the discerning eye can pick up the contour of a wall running parallel with the west foundation wall under the blacktop pavement. For a brief distance, between the point where the road swings eastward from it and the private driveway covers it again, excavation exposed this wall. Designated Wall C, it was 22 inches thick, entirely of brick, with no evidence remaining of red sandstone on the outside. The exterior surface was 9.5 feet beyond the west foundation wall.
