be post- 1 375, provided the associated pottery was not exotic but repre- 

 sentative of local types at that time. The finding of Four-mile poly- 

 chrome in these 15 rooms places its time unquestionably as shortly 

 after 1383, although it was present in rooms dating 1375 and may even 

 have been in existence 25 or 30 years earlier. That it had not been 

 developed by A. D. 1300 is shown by the results of excavations at 

 Pinedale, where an antecedent form was in existence at that time 

 and Four-mile polychrome was absent. Nor do we know exactly 

 how long it survived after 1383. Showlow ruin was probably aban- 

 doned at the close of the 14th or early in the 15th century just before 

 the Hopi Jeddito black-on-yellow penetrated the region in any ap- 

 preciable amount. In addition to its characteristic polychrome/ Four- 

 mile ruin contains an abundance of the Hopi yellow (Jeddito black-on- 

 yellow) which would place the abandonment of that site after Show- 

 low. But how long after, we are not ready to say. The absence of 

 Sikyatki polychrome at Four-mile ruin implies its abandonment prior 

 to 1450 A. D. 



Plain redzvare. — In the later period at Showlow plain red bowls 

 and ollas were made and used. Sherds were not found in the lower 

 deposits. 



A nearly complete, plain red olla seems representative as far as our 

 sherd collections show. Its paste is gray and tempered with coarse 

 sand ; its outer surface bears a red slip. Firing clouds are common on 

 these plain red ollas. The shape is similar to the Four-mile poly- 

 chrome ollas except that the upper body is flatter and the neck more 

 cylindrical. Plain red bowls are technologically the same as Four- 

 mile polychrome bowls except that the decorations are omitted. 

 Several nearly complete specimens and numerous sherds indicate 

 that they were seldom over 8 inches in diameter. 



Corrugated. — In the upper Showlow level, corrugated pottery occurs 

 only as ollas. The paste is gray, quartz tempered, and crumbly. Cor- 

 rugations and indentations are much the same as in vessels of the 

 older horizon (pi. 9, fig. 2, nos. i and 2). but a new treatment, not 

 found in the lower rooms, has come into general use. In this the coils 

 were so manipulated as to give the surface shallow horizontal flutings 

 or ribs (pi. 9, fig. 2, nos. 3, 4, 5, and 6). 



The finely corrugated vessels bearing exterior decoration are absent 

 in this level. 



' Type specimens of Four-mile polychrome vessels are to be seen in the U. S. 

 National Museum ; Gila Pueblo, Globe, Arizona ; Arizona State Museum, 

 Tucson; and the Museum of Northern Arizona, Flagstaff.
