Deeply impressed with the conviction that the continuance of slavery is one of the most active causes of the continuance of the unhappy condition in Cuba, I regret to believe that citizens of the United States, or those claiming to be such, are large holders in Cuba of what is there claimed as property, but which is forbidden and denounced by the laws of the United States.  They are thus, in defiance of the spirit of our own laws, contributing to the continuance of this distressing and sickening contest.  In my last annual message I referred to this subject, and I again recommend such legislation as may be proper to denounce, and, if not prevent, at least to discourage American citizens from holding or dealing in slaves.

It is gratifying to announce that the ratifications of the convention concluded under the auspices of this Government between Spain on the one part and the allied Republics of the Pacific on the other, providing for an armistice, have been exchanged.  A copy of the instrument is herewith submitted.  It is hoped that this may be followed by a permanent peace between the same parties.

The differences which at one time threatened the maintenance of peace between Brazil and the Argentine Republic it is hoped are in the way of satisfactory adjustment.

With these States, as with the Republics of Central and of South America, we continue to maintain the most friendly relations.

Our treaty relations with Japan remain unchanged.  An imposing embassy from that interesting and progressive nation visited this country during the year that is passing, but, being unprovided with powers for the signing of a convention in this country, no conclusion in that direction was reached.  It is hoped, however, that the interchange of opinions which took place during their stay in this country has led to a mutual appreciation of the interests which may be promoted when the revision of the existing treaty shall be undertaken.

In this connection I renew my recommendation of one year ago, that—­
