south wall of the first story of room D is intact; an opening which would seem to indi- 
cate the position of the passageway into the south room has its vertical jambs still 
well preserved, but its top has fallen and is very much broken. 
Room E, SoutrH Room 
The south chamber of the ruin, like the north, extends across the whole end of 
the ruin. Its greatest length is thus east and west. Its northern wall forms the 
southern side of the east, west, and central chambers B, D, and C, just as the southern

wall of the northern chamber A separates this room from the same members of the 
middle series. As with its northern fellow, there are openings into the lateral 
chambers B and D, the western and eastern rooms, but no signs of the existence of an 
entrance at any time into the central chamber C. The southeastern angle of room E, 
which is at the same time the southeastern corner of the ruin, is broken down so that 
a gap is formed, by which alone one can enter the room. Possibly this opening is 
not wholly the product of natural destruction. Two great gaps break the continuity 
of the southern wall, but the southwest corner of the chamber is entire from the ground 
to a considerable height.
