It being known that the treaty was formed under these circumstances, not a doubt was entertained that His Catholic Majesty would have ratified it without delay.  I regret to have to state that this reasonable expectation has been disappointed; that the treaty was not ratified within the time stipulated and has not since been ratified.  As it is important that the nature and character of this unexpected occurrence should be distinctly understood, I think it my duty to communicate to you all the facts and circumstances in my possession relating to it.

Anxious to prevent all future disagreement with Spain by giving the most prompt effect to the treaty which had been thus concluded, and particularly by the establishment of a government in Florida which should preserve order there, the minister of the United States who had been recently appointed to His Catholic Majesty, and to whom the ratification by his Government had been committed to be exchanged for that of Spain, was instructed to transmit the latter to the Department of State as soon as obtained, by a public ship subjected to his order for the purpose.  Unexpected delay occurring in the ratification by Spain, he requested to be informed of the cause.  It was stated in reply that the great importance of the subject, and a desire to obtain explanations on certain points which were not specified, had produced the delay, and that an envoy would be dispatched to the United States to obtain such explanations of this Government.  The minister of the United States offered to give full explanation on any point on which it might be desired, which proposal was declined.  Having communicated this result to the Department of State in August last, he was instructed, notwithstanding the disappointment and surprise which it produced, to inform the Government of Spain that if the treaty should be ratified and transmitted here at any time before the meeting of Congress it would be received and have the same effect as if it had been ratified in due time.  This order was executed, the authorized communication was made to the Government of Spain, and by its answer, which has just been received, we are officially made acquainted for the first time with the causes which have prevented the ratification of the treaty by His Catholic Majesty.  It is alleged by the minister of Spain that this Government had attempted to alter one of the principal articles of the treaty by a declaration which the minister of the United States had been ordered to present when he should deliver the ratification by his Government in exchange for that of Spain, and of which he gave notice, explanatory of the sense in which that article was understood.  It is further alleged that this Government had recently tolerated or protected an expedition from the United States against the Province of Texas, These two imputed acts are stated as the reasons which have induced His Catholic Majesty to withhold his ratification from the treaty, to obtain explanations respecting which it is repeated that an envoy would be forthwith dispatched to the United States.  How far these allegations will justify the conduct of the Government of Spain will appear on a view of the following facts and the evidence which supports them:
