ADMINISTRATIVE REPORT XXIX 



The structure of the earth inouuds of eastern Mexico 

 shows that they were foundations of buildings and are 

 not composed of fallen walls. Their form is pyramidal, 

 closely resembling that of so-called temple mounds in the 

 southern part of the United States. There is also a gen- 

 eral resemblance in artifacts found in the mounds of the 

 two regions, but the resemblance is apparently not suffi- 

 ciently close to warrant the drawing of conclusions 

 regarding the degree of relationship or the extent of 

 the communication that existed between the peoples of 

 these regions. The indications are, however, that the 

 relationship of the tribes of eastern Mexico with the 

 mound -building tribes of our Southern states was much 

 closer than with the peoples of the arid region of the 

 Southwest, or even Vvdth those of the plateau tribes of 

 northern Mexico.
