House remains were plentiful along- the road and the narrow trails. 

 They began with those previously noted in Johnson Run ' and 

 included the small exposed ruins near Cape Royal and Cape Final, 

 overlooking the Grand Canyon. The remains are those, usually, 

 of one-, two-, or three-room structures ; their walls are of irregular 

 and entirely unworked blocks of limestone, sandstone, or chert, 

 depending upon the character of the material nearest the site 

 occupied. Such blocks were picked up by the ancients from the 

 surface of the ground and apparently were laid in large quantities

of mud : numerous small fragments were added as a support for the 

 mortar and as a partial protection against the action of the elements. 

 The small number of sizable building stones on some sites, in pro- 

 portion to the quantities of lesser pieces, suggests that certain houses 

 may have been constructed chiefly of mud, although real adobe is 

 not to be found in the region. In several of these it is obvious that 

 the walls included but one or two courses of rock — there are no 

 remaining traces of others. In many instances the stones at the 

 bottom of the wall were placed on edge, their upper, unworked 

 surfaces probably supporting rough masonry or rubble. 



Potsherds collected near the ruins indicate that the development of 

 the ceramic art among these ancient people was not far behind that
