The Senate showed what its members thought of such manoeuvres by a speedy and unanimous vote in ratification of the Treaty.

Rejection of
the Treaty by
the Spanish
Government.

The Spanish Government, on the other hand, rejected the Treaty. Mr. Adams felt, at the moment, that this was a blow to his reputation as a diplomatist, and perhaps to his chances for the presidency. But it did not prove to be such. Had the Treaty been then ratified three large land grants made by the Spanish King to certain Spanish nobles, at a date earlier than Mr. Adams had supposed, would not have been extinguished by it. The rejection of the Treaty by the Spanish Government, which at the same time sent another Ambassador, General Vivês, to take the place of Don Onis, and to renew negotiations on the subject, gave Mr. Adams the opportunity to insist upon the cession of Florida with the extinguishment of the above mentioned grants.

Resumption of
negotiations.

When the new Ambassador arrived, the country was in the midst of the excitement over the question of slavery extension in the Louisiana territory, the history of which will be related in a succeeding chapter. The effect of this agitation was to arouse some doubt in the minds of those opposed to the extension of slavery in regard to the expediency of any addition to the territory of the United States southward. Mr. Adams himself felt the influence of this doubt, and was prompted, in part at least, by it to assume an attitude of indifference toward the new propositions of the Spanish Ambassador. He gave the Ambassador to understand that Spain could make such a treaty with the United States in regard to the subject as would be satisfactory to the latter, or take the consequences of leaving things as they were. The unshakable determination of Mr. Adams won the day, and the old Treaty, with a new provision extinguishing the above mentioned land grants, was finally ratified by both Governments, two years after the date of the original agreement between Mr. Adams and Don Onis.

The new Treaty ratified
by the Senate and by
the Spanish Government.
