Relations with Europeans in the Beagle Channel area in the southern area of the island of Tierra del Fuego were somewhat more cordial than with the ranchers. Thomas Bridges, who had been an Anglican missionary at Ushuaia, retired from that service. He was given a large land grant by the Argentine government, where he founded Estancia Harberton. Lucas Bridges, one of his three sons, did much to help the local cultures. Like his father, he learned the languages of the various groups and tried to provide the natives with some space in which to live their customary lives as "lords of their own land". The forces of change were against them, and the indigenous people continued to have high fatality rates as their cultures were disrupted. Lucas Bridges' book, "Uttermost Part of the Earth" (1948), provides sympathetic insight into the lives of the Selk'nam and Yahgan.
