A CAMP OF FISHERMEN AND GUANO-GATHERERS : LOBOS DE TlERRA 



The large house in right background is the office and residence of an American firm, con- 

 tractor for the Peruvian Corporation. The smaller houses are offices for minor officials. 



A DESERTED CAMP OF GUANO-WORKERS : CHINCHA ISLANDS 



The workers in the guano deposits are practically all Peruvians of the ancient stock. 

 Their camps are extremely simple, the huts consisting of skeleton frames of wood covered 

 with burlap or old guano sacks.
