"That is our one industry," answered the young man. "Many years ago my father discovered the pearl fisheries. It was after he had purchased the island, but he recognized the value of the pearls and brought a colony of people from America to settle at Sangoa and devote their time to pearl fishing. Once or twice every year we send a ship to market with a consignment of pearls to our agent, and--to be quite frank with you--that is why I am now able to build the picture theatres I have contracted for, as well as the film factory."
