TOZZER] EXCAVATION AT SANTIAGO AHUITZOTLA, MEXICO 41 



probability, with all the other rooms of the Main Structure. Room 

 I, as has already been pointed out, was filled with adobes. Between 

 and above the adobes over the whole extent of this room Aztec types 

 of pottery and figurines were found. Floor A' on the western side 

 is the remains of a floor which may have covered the greater part of 

 the site and connected with Floor A in the center. Remains of a 

 layer of tepetate in some places high up in the filling of Room II 

 may indicate this liighest floor level, as tepetate was often used in 

 place of adobes immediately under the floors. 



There may have been still another floor over A, as two layers of 

 adobes were found covering the greater part of the floor. 



Emphasis must again be laid on the fact that the divisions into 

 periods is only suggestive. There is often opportunity for several 

 interpretations of the floor levels. A knowledge of other sites of this 

 character in the Valley of INIexico would be a great help in deciding 

 many unsettled points. No attempt has been made to hazard a guess 

 as to the length of time for any of the periods. 



ARTIFACTS 



All the objects found in this excavation are in the Museo Nacional 

 in Mexico City. Unfortunately it was necessary to leave Mexico 

 before a complete study of the collection could be made. This part 

 of the report has been written, therefore, from notes and drawings 

 but without any of the collection at hand. 



In discussing the objects from this mound it may be assumed that 

 the various artifacts belong to the Toltec culture unless special men- 

 tion is made to the contrary. The objects of Aztec culture are com- 

 paratively few in number and relatively unimportant. A few things 

 which are clearly pre-Toltec or Archaic were encountered. These 

 are sporadic and do not indicate that the site can be dated back to 

 the time of the earliest occupation of the valley. Attention is called 

 to the list of illustrations (pp. 11, 12), Avhere there is given, as ac- 

 curately as possible, the location of many of the objects. 



Skeletal remains. — The human remains were not numerous. In 

 no case was a burial found in direct connection with objects. In 

 Pit XV, 2.35 m. beloAv the floor of Room XI, a skeleton was found. 

 Owing to the subsidence of the ground at this place the bones were 

 not in place. In Floor O, 1.10 m. outside the eastern wall of Room 

 XIII, 1 m. from the surface, a second skeleton Avas found resting 

 on the adobe floor. The head pointed toward the west and the 

 body lay on its back Avith the legs flexed. At the crossing in 

 Tunnels h and / charred human bones were found mixed with char- 

 coal. A few scattered human bones came to light in excavating the 

 wells.
