Fig. 116. — Repairing third-story walls in Pueblo Bonito. Some of these high 

 walls had been so weakened by vandalism and the elements that their repair 

 was necessary before excavation could safely be undertaken beneath. Ihe 

 work will serve, also, to preserve the present height of the walls for many 

 years to come. (Photograph by O. C. Havens. Courtesy of the National
