The claw is elastic and strong, and answers the purpose very well.

My Mexicans understood at once to what use they had been put.
As already alluded to, trincheras were also found in Cave Valley, where they were quite numerous.

There was one or more in every ravine and gully, and what was a new feature, some were built across shallow drainages on the very summit of a hill.

This summit was a bald conglomerate, about 150 feet above the valley.

In one place we observed eight trincheras within 150 feet of each other, all built of large stones in the cyclopean style of masonry.
