and return with the information acquired in the course of two summers.
Their arms and accouterments, some instruments of observation, and light
and cheap presents for the Indians would be all the apparatus they could
carry, and with an expectation of a soldier's portion of land on their
return would constitute the whole expense. Their pay would be going on
whether here or there. While other civilized nations have encountered
great expense to enlarge the boundaries of knowledge by undertaking
voyages of discovery, and for other literary purposes, in various parts
and directions, our nation seems to owe to the same object, as well
as to its own interests, to explore this the only line of easy
communication across the continent, and so directly traversing our own
part of it. The interests of commerce place the principal object within
the constitutional powers and care of Congress, and that it should
incidentally advance the geographical knowledge of our own continent
can not but be an additional gratification. The nation claiming the
territory, regarding this as a literary pursuit, which it is in the
habit of permitting within its dominions, would not be disposed to view
it with jealousy, even if the expiring state of its interests there did
not render it a matter of indifference. The appropriation of $2,500 "for
the purpose of extending the external commerce of the United States,"
while understood and considered by the Executive as giving the
legislative sanction, would cover the undertaking from notice and
prevent the obstructions which interested individuals might otherwise
previously prepare in its way.
