present road. Floor F is 0.7 m. higher than the floor of IX and at 

 one place is lined with stones (pi. 1, 14). It was built after Koom 

 IX, as Floor H rims under the edge of F. The remains of a wall 

 set in plaster were noted along the eastern edge of Floor F. This 

 is not shown in the plan. 



Rooms VII, VIII. — The first opens from IX on the south. Excava- 

 tions were made to the south of these rooms, but nothing was found. 

 The floor at the southwestern corner of Koom IX was badly broken 

 by subsidence. This extended into VII. This sinking of the floor 

 was due, as already noted, to the thick bed of ash beneath. It was 

 at this point that Pit XVI was dug. Room VIII opens from Room 

 VII and has no connection with Room IX. 



Room XI. — The room second in importance in the Southern Ex- 

 tension is Room XI, opening from Room IX by a clearly marked 

 doorway (pi. 6, a). The northern side of the northern wall is cov- 

 ered by Floor B. Tunnels a and h (pi. 2) show, however, the north- 

 ern face of the wall. There is a slight projection of the wall on the 

 southern side. On the western wall, some distance to the north of 

 the doorway into Room IX, a semicircular depression is noted run- 

 ning from the floor to the present top of the wall. It was evidently 

 filled at some time with a post. In the center of the northern end 

 of Room XI there is a mass of plaster mixed with large stones (pi. 1, 

 12), which may have been the foundation for a post to support the 

 roof. A broken mass of adobes Avas noted at the ^southern end of 

 the room (U), but this had fallen into the depression made by the 

 subsidence of the floor due to the thick bed of ash beneath. The 

 floor was removed, as stated in another place, and Pit XV was made 

 here. 



Floor E, a curious high-level construction, was found at the south- 

 eastern corner of Room XI (pi. 7, «). 0.84 m. above the floor of XI. 

 Only a narrow piece of the floor is preserved and it ends abruptly 

 on the northern side with no evidence of a wall. The remains of a 

 naiTow wall are found on the western side extending out beyond the 

 southern limit of Room XI. The floor of the latter room runs behind 

 this piece of higher floor. 



In excavating the northern end of Room XI two smaii pieces of 

 floor were found at the same level as Floor J to the south of Room X. 

 Some squared stones were also seen near the eastern wall of this 

 room above the floor. These two features are not shown in the plan. 

 Outside the eastern wall of XI three pieces of a rough floor were 

 found (pi. 1, L, L', L"). Excavations were made along this wall 

 but no remains of a room or rooms were noted. These rough floors 

 may have extended around the outside of the building. At the south- 

 ern side of Floor L", on a leA^el with the floor of XI, the remains of 

 a stone fireplace appeared.
