He spoke upon the theme which he had mastered so thoroughly. He
demonstrated by copious historical proofs and masterly logic that the
fathers who created the Constitution in order to form a more perfect
union, to establish justice, and to secure the blessings of liberty to
themselves and their posterity, intended to empower the Federal
Government to exclude slavery from the Territories. In the kindliest
spirit he protested against the avowed threat of the Southern States to
destroy the Union if, in order to secure freedom in those vast regions
out of which future States were to be carved, a Republican President were
elected. He closed with an appeal to his audience, spoken with all the
fire of his aroused and kindling conscience, with a full outpouring of
his love of justice and liberty, to maintain their political purpose on
that lofty and unassailable issue of right and wrong which alone could
justify it, and not to be intimidated from their high resolve and sacred
duty by any threats of destruction to the government or of ruin to
themselves. He concluded with this telling sentence, which drove the
whole argument home to all our hearts: "Let us have faith that right
makes might, and in that faith let us to the end dare to do our duty as
we understand it." That night the great hall, and the next day the whole
city, rang with delighted applause and congratulations, and he who had
come as a stranger departed with the laurels of great triumph.

Alas! in five years from that exulting night I saw him again, for the
last time, in the same city, borne in his coffin through its draped
streets. With tears and lamentations a heart-broken people accompanied
him from Washington, the scene of his martyrdom, to his last
resting-place in the young city of the West where he had worked his way
to fame.
