Illinois River, his Arkansas post, his competition with the
Indians and the English, and with other activities. The tenth
chapter carries the title, "Imprint on the Mississippi Valley,"
and in it the author says: "By reason of Tonty's contributions
it may be said that he paved the way for the vanguard of
Americans lured to the west by 'manifest destiny.' American
advance into the Louisiana country was greatly facilitated by
the economic development of that region under France, and
in that development, Tonty had played a significant role." In
this last chapter "Tonty's place in history is admirably summed
up," as Professor Herbert E. Bolton says in the foreword.

is now the California-Oregon boundary, thus being for the
first time assured of a transcontinental domain."
Brooks points out that although the Spanish patriot assembly,
the Junta Central of Aranjuez, sent Don Luis de Onis as its
