I invite your attention to the correspondence between Her Britannic Majesty's minister accredited to this Government and the Secretary of State relative to the detention of the British ship Perthshire in June last by the United States steamer Massachusetts for a supposed breach of the blockade. As this detention was occasioned by an obvious misapprehension of the facts, and as justice requires that we should commit no belligerent act not rounded in strict right as sanctioned by public law, I recommend that an appropriation be made to satisfy the reasonable demand of the owners of the vessel for her detention. I repeat the recommendation of my predecessor in his annual message to Congress in December last in regard to the disposition of the surplus which will probably remain after satisfying the claims of American citizens against China, pursuant to the awards of the commissioners under the act of the 3d of March, 1859. If, however, it should not be deemed advisable to carry that recommendation into effect, I would suggest that authority be given for investing the principal, over the proceeds of the surplus referred to, in good securities, with a view to the satisfaction of such other just claims of our citizens against China as are not unlikely to arise hereafter in the course of our extensive trade with that Empire. By the act of the 5th of August last Congress authorized the President to instruct the commanders of suitable vessels to defend themselves against and to capture pirates. This authority has been exercised in a single instance only. For the more effectual protection of our extensive and valuable commerce in the Eastern seas especially, it seems to me that it would also be advisable to authorize the commanders of sailing vessels to recapture any prizes which pirates may make of United States vessels and their cargoes, and the consular courts now established by law in Eastern countries to adjudicate the cases in the event that this should not be objected to by the local authorities. If any good reason exists why we should persevere longer in withholding our recognition of the independence and sovereignty of Hayti and Liberia, I am unable to discern it. Unwilling, however, to inaugurate a novel policy in regard to them without the approbation of Congress, I submit for your consideration the expediency of an appropriation for maintaining a charge d'affaires near each of those new States. It does not admit of doubt that important commercial advantages might be secured by favorable treaties with them.
