TOZZBB] EXCAVATION AT SANTIAGO AHUITZOTLA, MEXICO 23 



In a few cases the edge of a floor is lined with a row of worked 

 stones set ahnost flush with the floor. Along a part of the eastern 

 side of Room I a row of stones (pi. 1, 3) seems to indicate possibly 

 a doorway into the Patio. The southern edge of Floor Q in Tunnel / 

 (pi. 2) and the floor in Tunnel j) show a line of worked stones set 

 flush with the floor. The edge of the depressed Floor H in Room 

 IX is lined with worked stones. Squared stones are also found on 

 the edge of Floor F (pi. 1, 14). 



Drains. — With the exception of the perforated stone found over 

 the cluster of four wells (p. 24), there are no signs of drains, a 

 feature very common at Teotihuacan. 



Roofs. — As might be expected, there are no remains of the roof 

 construction. This was undoubtedly of some perishable material. 

 The columns at either end of Room I and those around the eastern 

 and southern sides of Room IX were probably supports for the roof.^ 

 The projections of the wall on the eastern and western sides of 

 Room I probably served as the support for roof-beams. In Room XI 

 the remains of a mass of cement (pi. 1, 12) near the northern end 

 may show the foundation for wooden beams to support the roof of 

 this wide room. A similar feature was probably present at the 

 southern end of the same room (pi. 1, 11), although it had fallen in, 

 owing to the subsidence of the floor. In the center of Room X a 

 large stone (pi. 1, 17) may have been the foundation for a wooden 

 support. 



There are several wide rooms which show no remains of the 

 methods used to support the roof. At Teotihuacan also there are 

 many rooms too wide to have been bridged by a single beam, and yet 

 no pillar or wall appears at the present time. 



Stairways. — There are no remains of stairways. Steps were prob- 

 ably necessary leading from the Eastern Terrace to the Patio on the 

 level with Room I, provided our reconstruction is correct. 



Fireplaces. — The only suggestion of a fireplace in the floor is in 

 Room VI (pi. 1, 18; pi. 7, &). It is a depression lined with squared 

 stones, and it was found filled with ashes. No remains of fire were 

 found on the stones. Outside the eastern wall of Room XI several 

 worked stones were found together. They seemed to have formed a 

 part of a fireplace at this point. In the northern end of Room I, 

 0.5 m. above the floor, a mass of burned adobe was found, 0.4 m. thick 



^Compare the plan of rooms excavated at San Juan Teotihuacan by Charnay (" Ancient 

 Cities of the New World," New York. 1887, p. 145). He writes. "The center of the 

 room is occupied by six pillars, on which rose stone, brick, or wood columns bearing the 

 roof." It is evident from this description that the columns were not standing at the 

 time of his explorations. Seler (op. cit., pp. 408-409) assumes that the piers were of 

 wood when he writes, " In Teotiuacan kennen wir nur die unteren Theile der Wiinde, 

 diese sind aber auch hler durchweg unten abgebiischt, und auch die Untersiitze der 

 Pfeller, — die selbst vermuthlich aus vergiinglichem Materiale, aus Holz, bestanden ha- 

 ben, — fallen regelmassig nach den vier Seiten ab."
