TOZZEK] EXCAVATION AT SANTIAGO AHUITZOTLA, MEXICO. 55 



excavation of this kind as compared with investigations on such 

 structures as the pyramids of San Juan Teotihuacan, but the im- 

 portance of the excavation of the smaller sites is great if we are to 

 reconstruct the culture of the prehistoric peoples of the Valley of 

 Mexico.
