was directly below the 1926 wall, with its north face even with that of the 1926 wall. A large, well-trimmed, saw-cut limestone block, 20 x 18 x 18 inches, was found set into a yellow, sandy- lime mortar in this trench. The mortar was similar to that found in abundance in the foundation trench of the Honore Grenet store, located in Units A and AII. Other than this cut block, the two ditches in Unit EII contained nothing but rubble and fill. Both ditches and posthole lines date after the upper ditch fill, and all contained Anglo-American artifacts.

Unit AII

In the area of a north-south wall fragment found just west of Unit A, a second section of the 1926 wall and sidewalk was removed and the area excavated. Unit AII was a 6-x-5-ft unit, the east edge of which was 2.75 ft west of the west edge of Unit A. The stratigraphy was virtually identical to that seen in Unit A. We determined the wall foundation in this area was of eighteenth-century date (probably after 1750), built into an intrusive footing trench from a higher level, now destroyed. Within the limits of the unit we could not determine whether the wall was late Spanish or Anglo-American. The wall presumably reached as far north as the footing trench for the Honore Grenet store north wall, but definitely went no further north. The Honore Grenet wall was found to be 2 ft 5 inches wide and to reach to a depth approximately 60 inches below the surface of the courtyard. The outer face of the wall was even with the outer face of the 1926 wall.

Stockade Trench (dug to construct the stockade wall)

The south face of the stockade trench was cleaned and scraped and a complete profile drawn. In the course of this work, traces of three walls were found extending toward the north. Two areas of rubble, believed to be walls, were also located. One of these was immediately adjacent to the west edge of Unit E.

At a distance of 11 ft 8 inches west of the edge of Unit E along the stockade trench, just west of the stone wall associated with a adobe wall and floor found in Unit EII, traces of an apparent footing trench running east-west were found. These traces, seen along the north face of the stockade trench, consisted of fist-sized rocks and dark gray clay in a thin deposit on this face. This deposit was lower than the disturbed area associated with the 1926 wall, and distinctly different from the light gray soil found elsewhere in the stockade trench at this level. Removal of this deposit showed the light gray background soil behind it. Apparently the excavation of the stockade trench removed the majority of this footing trench, leaving only 2-3 inches of the northern side of the trench in the ground. The traces curve upward abruptly toward the east of a point 11 ft 8 inches west of Unit EII, and from that point west, the traces slowly merge with the footing of the 1926 wall.

Eight feet from the west face of unit EII, a second north-south wall foundation was found in the stockade trench south profile. Upon detailed examination, this wall was found to extend at right angles to the 1926 wall and to be the lower section of a footing trench filled with the remains of a stone wall built from some higher surface no longer in existence, similar to that found in Unit AII. This is a substantial wall, 2.5 ft thick at its foundation. No other details could be determined about this wall within the limits of the stockade trench.

1926 Wall Trench

After the completion of our limited additional testing, the remains of the 1926 wall foundation were removed by construction workers. We conducted constant monitoring of the removal, resulting in the collection of additional information.

The large, square limestone block set into yellow, sandy mortar in the wall trench directly below the 1926 wall was duplicated at intervals averaging about 9 ft 10 inches, center to center,
