She's got nothing to mourn about--nobody's died, has there?
"Hiu-hiu-hia-a-a,ah! Hia-a-a-a-ah!" wailed Annie-Many-Ponies in her tent, because she would never again look upon the face of Wagalexa Conka--or if she did it would be to see his anger blaze and burn her heart to ashes.

To her it was as though death sat beside her; the death of Wagalexa Conka's friendship for her.

She forgot his harshness because he thought her disobedient and wicked.

She forgot that she loved Ramon Chavez, and that he was rich and would give her a fine home and much love.

She forgot everything but that she had sworn an oath and that she must keep it though it killed faith and kindness and friendship as with a knife.
So she wailed, in high-keyed, minor chanting unearthly in its primitive inarticulateness of sorrow, the chant of the Omaha mourning song.
