in any degree under the control of the Spanish minister at Washington.  Any communication which he may hold with an agent of a foreign power is informal and matter of courtesy.  Anxious to put an end to the existing inconveniences (which seemed to rest on a misconception), I directed the newly appointed minister to Mexico to visit Havana on his way to Vera Cruz.  He was respectfully received by the Captain-General, who conferred with him freely on the recent occurrences, but no permanent arrangement was effected.

In the meantime the refusal of the Captain-Generalto allow passengers and the mail to be landed in certain cases, for a reason which does not furnish, in the opinion of this Government, even a good presumptive ground for such prohibition, has been made the subject of a serious remonstrance at Madrid, and I have no reason to doubt that due respect will be paid by the Government of Her Catholic Majesty to the representations which our minister has been instructed to make on the subject.

It is but justice to the Captain-General to add that his conduct toward the steamers employed to carry the mails of the United States to Havana has, with the exceptions above alluded to, been marked with kindness and liberality, and indicates no general purpose of interfering with the commercial correspondence and intercourse between the island and this country.

Early in the present year official notes were received from the ministers of France and England inviting the Government of the United States to become a party with Great Britain and France to a tripartite convention, in virtue of which the three powers should severally and collectively disclaim now and for the future all intention to obtain possession of the island of Cuba, and should bind themselves to discountenance all attempts to that effect on the part of any power or individual whatever.  This invitation has been respectfully declined, for reasons which it would occupy too much space in this communication to state in detail, but which led me to think that the proposed measure would be of doubtful constitutionality, impolitic, and unavailing.  I have, however, in common with several of my predecessors, directed the ministers of France and England to be assured that the United States entertain no designs against Cuba, but that, on the contrary, I should regard its incorporation into the Union at the present time as fraught with serious peril.

Were this island comparatively destitute of inhabitants or occupied by a kindred race, I should regard it, if voluntarily ceded by Spain, as a most desirable acquisition.  But under existing circumstances I should look upon its incorporation into our Union as a very hazardous measure.  It would bring into the Confederacy a population of a different national stock, speaking a different language, and not likely to harmonize with the other members.  It would probably affect in a prejudicial manner the industrial interests of the South, and it might revive those conflicts of opinion between the different sections of the country which lately shook the Union to its center, and which have been so happily compromised.
