Camp Chopunnish (Long Camp), waiting for snow to melt — Patrick Gass: May 27, 1806

several of our men went to the villages around us to procure
roots. These roots are a good diet, but in general we do not
relish them so well as meat. We therefore killed another
horse to day, which one of the natives gave us some time ago
for that purpose. He was so wild and vicious that we could
not manage him or do any thing with him.
Our sick man is getting some better, and the interpreter’s
child is recovering fast. The Indian, that we have under
cure, had another sweat to day; and our horses, that have had
the quieting operation performed on them are all mending.
In the afternoon some rain fell, and three of our hunters came
in, and brought with them five deer, they had killed: three
men also came in from the villages and brought a good supply
of roots; six yet remained out.
