The Wasichus* did not kill them to eat; they
killed them for the metal that makes them crazy,
and they took only the hides to sell. Sometimes
they did not even take the hides, only the
tongues; and I have heard that fire-boats came
down the Missouri River loaded with dried bison
tongues.… And when there was nothing left
but heaps of bones, the Wasichus came and
gathered up even the bones and sold them.
