THE RAINBOW

The Northern Mewuk say:

Ku-yet'-tah the Rainbow comes to tell the people a baby is born. When anyone sees Ku-yet'-tah he knows that somewhere a new baby has come. Everybody knows that.

The Hookooeko of Nicasio and Tomales Bay say:

Kah-chah the Rainbow is the bow of O'-ye the Coyote-man.
