Our claims upon Portugal have been during the past year prosecuted with renewed vigor, and it has been my object to employ every effort of honorable diplomacy to procure their adjustment. Our late charge d'affaires at Lisbon, the Hon. George W. Hopkins, made able and energetic, but unsuccessful, efforts to settle these unpleasant matters of controversy and to obtain indemnity for the wrongs which were the subjects of complaint. Our present charge d'affaires at that Court will also bring to the prosecution of these claims ability and zeal. The revolutionary and distracted condition of Portugal in past times has been represented as one of the leading causes of her delay in indemnifying our suffering citizens. But I must now say it is matter of profound regret that these claims have not yet been settled. The omission of Portugal to do justice to the American claimants has now assumed a character so grave and serious that I shall shortly make it the subject of a special message to Congress, with a view to such ultimate action as its wisdom and patriotism may suggest. With Russia, Austria, Prussia, Sweden, Denmark, Belgium, the Netherlands, and the Italian States we still maintain our accustomed amicable relations. During the recent revolutions in the Papal States our charge d'affaires at Rome has been unable to present his letter of credence, which, indeed, he was directed by my predecessor to withhold until he should receive further orders. Such was the unsettled condition of things in those States that it was not deemed expedient to give him any instructions on the subject of presenting his credential letter different from those with which he had been furnished by the late Administration until the 25th of June last, when, in consequence of the want of accurate information of the exact state of things at that distance from us, he was instructed to exercise his own discretion in presenting himself to the then existing Government if in his judgment sufficiently stable, or, if not, to await further events. Since that period Rome has undergone another revolution, and he abides the establishment of a government sufficiently permanent to justify him in opening diplomatic intercourse with it.
