To be sure he had promised Spain not to turn over Louisiana to another power; but he was quite as incapable as any Spanish statesman, or as Talleyrand himself, of so much as considering the question of breach of faith or loss of honor, if he could gain any advantage by sacrificing either.

Livingston was astonished to find that Napoleon had suddenly changed front, and that there was every prospect of gaining what for months had seemed impossible.

For some time there was haggling over the terms.

Napoleon at first demanded an exorbitant sum; but having once made up his mind to part with Louisiana his impatient disposition made him anxious to conclude the bargain.

He rapidly abated his demands, and the cession was finally made for fifteen millions of dollars.
The Boundaries Undecided.
The treaty was signed in May, 1805.
