PIE′GAN. One of the most interesting of the Algonquian tribes in North America. They are associated with the Siksika and the Kino or Bloods in the so-called Siksika confederacy, and over two thousand of them are on the Blackfeet agency in northwestern Montana. They are well disposed and tractable, and crimes are almost unknown among them. The other members of the confederacy extend northward into Canada, where they join their co-linguists, the Creeks (q.v.), to form the westernmost tribes of the most widely diffused language family in the Western Hemisphere.
