3.— Pottery rubbers. 



made of an extra piece of clay running 'across the top. Small shal- 

 low holes may cover a part or the whole of the top (fig. 3, a) . Figure 

 3, 6, shows a second variation with a pellet of clay added at one side 

 of the handle. 



Spiin dle a\ HORLb. — Three spindle whorls, 



Aztec ui type, were found near the surface of 



the mound. Figure 4, «, shows an unusual form. 



Ear plugs. — A single ear plug (fig. 4, h) came 



to light in excavating 



to the south of floor A. 



It is evidently from the 



Aztec culture. 



Molds, — These were 

 uncommon. Two were 

 ^ found for making the 



typical Toltec heads, 

 one for making an adorno, and one for molding a rosette or button. 

 Pottery. — No complete classification of the ceramics of the Valley 

 of Mexico has ever been attempted. Dr. Boas, in his "Album de 

 arqueologia mexicana hecho con 69 himinas," published by the In- 

 ternational School, Mexico, 1912, gives a large number of pottery 

 designs collected in the vicinity of Mexico City. Comparatively few 

 of these designs were duplicated in the shards from this mound. 

 When similar types occur, reference will be made to the Boas Album. 

 An attempt has been made here to indicate very roughly the various 

 types of pottery. This is presented merely as covering the collection 

 in question and not in 

 any way as an attempt 

 to work out a complete 

 classification of the ce- 

 ramics of this part of 

 the valley. It should lie 

 noted also that only dec- 

 orated shards and pots 

 are included. A fertile 

 field is open to the stu- 

 dent of ceramics in the 

 study of the undeco- 

 rated pottery. Practically no attention has ever been paid to this 

 phase of the subject. The decorated pottery of the Archaic, Toltec, 

 and Aztec cultures may usually be distinguished, but, as far as I 

 know, no one has yet attempted to classify the undecorated pottery 

 of these three horizons. In the following description it will be 

 assumed that the types belong to the Toltec culture unless mention is 

 made to the contrary.
