Soacatino Indians. A district visited by the troops of Moscoso, of the De Soto expedition, in 1542. It lay west of Mississippi river, bordering on the Eyeish and Anadarko, probably near the middle course of Red river. The Spaniards expected to find a large and rich province, but it was a thick forest, where the people lacked food; hence they abandoned the hope of reaching Mexico by land and returned to the Mississippi. The natives evidently belonged to the Caddoan family.
