HAVING DIFP'ICULTIES WITH A TRIPOD : MACHU PICCHU 



A distant view of Ingenuity Group, with Private Garden Group above it, as seen from 

 the vicinity of the semicircular tower. In taking these pictures, it was frequently neces- 

 sary to put the tripod on the shaky peak of a ruined gable, a process not always easy.

Typical masonry: machu picchu 



The outside wall of another group which was distinguished by having its own private 

 gardens on terraces so arranged that access to them could be had only by passing through 

 the houses of the group. These houses are built on a terrace whose retaining wall consists 

 of large blocks of solid masonry. The smaller wall on top of this is merely a screen for 

 defensive purposes. Notice the end of the stone conduit in the lower left-hand corner, en- 

 abling the courtyard of this group to be properly drained.
