we set five men at work to make a canoe for the purpose of fishing and passing the river. the Indians have already promised us a horse for this canoe when we have no longer any uce for her.

To day we made a small lodge of poles and covered it with grass, for Captain Lewis and Captain Clarke, as their tent is not sufficient to defend them from the rain.
—Patrick Gass

We devided our Store of merchindize amongst our party for the purpose of precureing Some roots &c. of the nativs to each mans part amounted to about an awl Knitting pin a little paint and Some thread & 2 Needles which is but a Scanty dependance for roots to take us over those Great Snowey Barriers (rocky mountains) which is and will be the Cause of our Detention in this neighbourhood probably untill the 10 or 1 of June. they are at this time Covered deep with Snow.

I and one more [Silas Goodrich] of the party went up to a village about 5 miles on South Side on the Side of a hill & Spring run we purchased some white roots Shappalell &C. Some of the women in the village were crying aloud at different times in the course of the day. I Signed the reason of their lamenting & they gave me to understand that they had lost Some of their Sons in battle and that was the custom among them when their relation died they mourn and lement a long time after the aged women only make a loud noise.
—John Ordway

we would make the men collect these roots themselves but there are several speceis of hemlock which are so much like the cows [cous] that it is difficult to discriminate them from the cows and we are affraid that they might poison themselves.
