_Assiniboin_
The Sioux, or Dakotas, of whom the Assiniboins are a branch, pretend
that thunder is an enormous bird, and that the muffled sound of the
distant thunder is caused by a countless number of young birds! The
great bird, they say, gives the first sound, and the young ones repeat
it; this is the cause of the reverberations. The Sioux declare that
the young Thunders do all the mischief, like boys who will not listen
to good advice; but the old Thunder, or big bird, is wise and
excellent; he never kills or injures any one!
