The New International Encyclopædia/Toba
TOBA, tō′bȧ (opposite, so called by the Guarani, as living on the opposite or western bank of the Paraguay). A powerful and savage people of Guaycuran stock, the most important tribe of the Chaco region of Northern Argentina. They rove along the Pilcomayo and Vermejo rivers. Their language is a dialect of that formerly spoken by the Abipone (q.v.), whom they exterminated about a century ago. They hunt and fight on horseback with the lance and bow, and are warlike and untamably hostile to all whites who attempt to enter the region.
