25Hietans was the term Sibley applied to the Comanches. Pichardo, how-
ever, also an authority on the Indian tribes states that Sibley was mistaken.
They were different. "The Hietanes were those whom the Spaniards called
Yutas." Sibley describes the Hietanes as nomads intermittently occupying
the area lying between the Trinity and the Brazos, crossing Red River, to
the heads of the Arkansas and the Missouri, and as far as the Rio Grande.
