such an enterprise to a successful issue, and of another event which was to furnish a new motive to its undertaking. Early in the year 1801, when Jefferson had but just taken his seat as President, Rufus King, Minister of the United States to England, wrote to Madison, Secretary of State, that the opinion at that time prevailed both at Paris and at London that Spain had ceded Louisiana and the Floridas to France.

Meanwhile the government at Washington pressed its ministers at both courts to use every effort to secure to the United States the Floridas and New Orleans, with the Mississippi as our western boundary, and the free navigation of the river to its mouth.
