On the 28th, in reply to a resolution, a Message was received from the President, transmitting sundry documents relating to the right of foreign nations to take guano from the Lobos islands, off the coast of Peru. On the 2d of June, Captain Jewett wrote to Mr. Webster, inquiring whether these islands were the possession of any single power, or whether they were open to the commerce of the world. Mr. Webster replied that the islands were uninhabited, that they had never been enumerated among the possessions or dependencies of any of the South American states, and that citizens of the United States would be protected in removing the valuable deposits upon them. At the same time the Secretary of the Navy ordered a vessel of war to be dispatched for the protection of American vessels engaged in this traffic. Under these assurances Captain Jewett and his associates fitted out some twenty vessels which were immediately dispatched to the islands in question. Mr. Webster's letter to Captain Jewett, meantime, having accidentally been made public, the Peruvian Minister, Senor Osma, in three successive notes, represented to the Government that the Lobos islands were dependencies of Peru, and that the United States could have no rightful claim to remove their valuable deposits. Mr. Webster replied to this claim on the 21st of August, by an elaborate argument showing that Peru had hitherto, by repeated acts, sustained the position that the islands do not belong to any of the South American states. They lie about thirty miles from the shore, and are uninhabited and uninhabitable. Citizens of the United States have visited them in pursuit of seals for half a century; and no complaint was made of this until 1833, when Peru issued a decree forbidding foreigners from visiting them for any such purpose. The United States Chargé at Lima immediately remonstrated against this decree, and requested its modification, so far as to permit citizens of the United States to continue pursuits in which they had been engaged for so many years. No reply was made to this remonstrance, and the citizens of the United States continued their avocations without any further interruption. Mr. Webster insists, therefore, that while these islands lie in the open ocean, so far from the coast of Peru as not to belong to that country by the law of proximity or adjacent position, the Government of Peru has not exercised any such acts of absolute sovereignty and ownership over them as to give to her a right to their exclusive possession as against the United States and their citizens by the law of indisputable possession. The Government of the United States is, however, disposed to give due consideration to all the facts of the case, and the President will therefore give such orders to the naval forces on that coast as will prevent collision until the case can be examined.
