The arbitrator in the case of the United States steamer Montijo, for the seizure and detention of which the Government of the United States of Colombia was held accountable, has decided in favor of the claim. This decision has settled a question which had been pending for several years, and which, while it continued open, might more or less disturb the good understanding which it is desirable should be maintained between the two Republics. A reciprocity treaty with the King of the Hawaiian Islands was concluded some months since. As it contains a stipulation that it shall not take effect until Congress shall enact the proper legislation for that purpose, copies of the instrument are herewith submitted, in order that, if such should be the pleasure of Congress, the necessary legislation upon the subject may be adopted. In March last an arrangement was made, through Mr. Cushing, our minister in Madrid, with the Spanish Government for the payment by the latter to the United States of the sum of $80,000 in coin, for the purpose of the relief of the families or persons of the ship's company and certain passengers of the Virginius. This sum was to have been paid in three installments at two months each. It is due to the Spanish Government that I should state that the payments were fully and spontaneously anticipated by that Government, and that the whole amount was paid within but a few days more than two months from the date of the agreement, a copy of which is herewith transmitted. In pursuance of the terms of the adjustment, I have directed the distribution of the amount among the parties entitled thereto, including the ship's company and such of the passengers as were American citizens. Payments are made accordingly, on the application by the parties entitled thereto. The past year has furnished no evidence of an approaching termination of the ruinous conflict which has been raging for seven years in the neighboring island of Cuba. The same disregard of the laws of civilized warfare and of the just demands of humanity which has heretofore called forth expressions of condemnation from the nations of Christendom has continued to blacken the sad scene. Desolation, ruin, and pillage are pervading the rich fields of one of the most fertile and productive regions of the earth, and the incendiary's torch, firing plantations and valuable factories and buildings, is the agent marking the alternate advance or retreat of contending parties.
