Fall 1974: ABC
Arthur Kennedy appeared as Sheriff Sam Jericho, and Taylor Lacher and Gloria DeHaven portrayed Hubbell Martin and Irene James, respectively, two other deputies. Nakia was up against The Carol Burnett Show on CBS at 10:00PM and after thirteen episodes the series was gone, its last episode airing on December 28th, 1974.
The problem with Nakia stemmed from its reliance on Native American culture. Although Forster made a convincing Navajo, many of the guest-stars looked or acted nothing like their Native American characters. Many of the plots relied on Nakia's native "abilities" (he was able to silently sneak up on someone while wearing his moccasins, for example). It's not surprising the series didn't last.
