from being overflowed; the water is of a greenish-yellow cast,
and much more transparent than that of the Missouri, which itself,
though clearer than below, still retains its whitish hue and a portion
of its sediment. Opposite the point of junction the current of the
Missouri is gentle, and two hundred and twenty-two yards in width;
the bed is principally of mud, the little sand remaining being wholly
confined to the points, and the water is still too deep to use the
setting-pole.

"If this be, as we suppose, the Musselshell, our Indian information is
that it rises in the first chain of the Rocky mountains not far from the
sources of the Yellowstone, whence in its course to this place it waters
a high broken country, well timbered, particularly on its borders, and
interspersed with handsome fertile plains and meadows. We have reason,
however, to believe, from their giving a similar account of the timber
where we now are, that the timber of which they speak is similar to that
which we have seen for a few days past, which consists of nothing more
than a few straggling small pines and dwarf cedars on the summits of the
hills, nine-tenths of the ground being totally destitute of wood, and
covered with short grass, aromatic herbs, and an immense quantity
of prickly-pear; though the party who explored it for eight miles
represented the low grounds on the river to be well supplied with
cottonwood of a tolerable size, and of an excellent soil. They also
report that the country is broken and irregular, like that near our
camp; and that about five miles up, a handsome river, about fifty
yards wide, which we named after Chaboneau's wife, Sacajawea's or the
Bird-woman's River, discharges into the Musselshell on the north or
upper side."

Later explorations have shown that the Musselshell rises in the
Little Belt Mountains, considerably to the north of the sources of the
Yellowstone. Modern geography has also taken from the good Sacajawea
the honor of having her name bestowed on one of the branches of the
Musselshell. The stream once named for her is now known as Crooked
Creek: it joins the river near its mouth, in the central portion of
Montana. The journal, under date of May 22, has this entry:--

"The river (the Missouri) continues about two hundred and fifty yards
wide, with fewer sand-bars, and the current more gentle and regular.
Game is no longer in such abundance since leaving the Musselshell. We
have caught very few fis
