"Although your route will be along the channel of the Missouri, yet
you will endeavour to inform yourself, by inquiry, of the character
and extent of the country watered by its branches, and especially
on its southern side. The North river, or Rio Bravo, which runs
into the gulf of Mexico, and the North river, or Rio Colorado,
which runs into the gulf of California, are understood to be the
principal streams heading opposite to the waters of the Missouri,
and running southwardly. Whether the dividing grounds between the
Missouri and them are mountains or flat lands, what are their
distance from the Missouri, the character of the intermediate
country, and the people inhabiting it, are worthy of particular

English traders and travellers; but if you can learn any thing
certain of the most northern source of the Missisipi, and of its
position relatively to the Lake of the Woods, it will be
interesting to us. Some account too of the path of the Canadian
traders from the Missisipi, at the mouth of the Onisconsing to

course, is desirable.
