prehistoric ruins, many of which are undescribed. Owing to the 

 scarcity of labor on account of the draft the exploration was 

 confined to a reconnoissance of the ruins iii the vast region lying 

 west of Fort Apache and including the Tonto Ikisin Forest. The 

 work covered a portion of this area and required 500 miles of travel 

 by various means of locomotion. Much of the country traversed 

 is very difficult, being broken by deep canyons eroded in the slopes 

 of the great Mogollon escarpment, known locally as the " rim " 

 or " mountain," a tremendous geogra])hic feature of dominant im- 

 portance, in which the rivers of southern Arizona take their rise.
