FHWKBES ] NAVAHO NATIONAL MONUMENT, ARIZONA 35 
we go up the river the conclusion is logical that the migration of the 
San Juan culture was down the river from east to west, rather than 
in the opposite direction. The scanty traditions known to the 
author support the belief in a migration from east to west. although 
there were exceptional instances of clan movements in the opposite 
direction. The general trend of migration would indicate that the 
ancestral home of the Snake and Flute people was in Colorado and 
New Mexico. 
It is evident from the facts here recorded that the ruins in the 
Navaho National Monument contain most important, most char- 
acteristic, and well-preserved prehistoric buildings, and that the 
problems they present are of a nature to arouse great interest in 
them. Having suffered comparatively little from vandalism, these 
are among the best-preserved monuments of the cliff-dwellers’ cul- 
ture in our Southwest, and if properly excavated and repaired they 
would preserve most valuable data for the future student of prehis- 
toric man in North America. It is not necessary to preserve all the 
ruins within this area, but it would be well to explore the region 
and to locate the sites of the ruins that it contains. 
/ RECOMMENDATIONS 
The writer has the honor to recommend that one of the largest two 
cliff-dwellings in the Navaho National Monument, either Betatakin 
or Kitsiel, be excavated, repaired, and preserved as a ‘“‘type ruin” 
to illustrate the prehistoric culture of the aborigines of this section 
of Arizona; also that this work be supplemented by excavation and 
repair of Inscription House, an ancient cliff-dwelling in West canyon. 
He also recommends that one or more of the ruins in West canyon 
be added to the Navaho National Monument and be permanently 
protected by the Government.
