The ninth article of the treaty between the United States and Spain provides that "all ships and merchandise of what nature soever which shall be rescued out of the hands of any pirates or robbers on the high seas shall be brought into some port of either State and shall be delivered to the custody of the officers of that port in order to be taken care of and restored entire to the true proprietor as soon as due and sufficient proof shall be made concerning the property thereof." The case of the _Amistad_, as was decided by the court, was not a case of piracy, and therefore not within the terms of the treaty; yet it was a case in which the authority of the master, officers, and crew of the vessel had been divested by force, and in that condition the vessel, having been found on the coast, was brought into a port of the United States; and it may deserve consideration that the salvors in this case were the officers and seamen of a public ship. It is left to Congress to consider, under these circumstances, whether, although in strictness salvage may have been lawfully due, it might not yet be wise to make provision to refund it, as a proof of the entire good faith of the Government and of its disposition to fulfill all its treaty stipulations to their full extent under a fair and liberal construction. JOHN TYLER. WASHINGTON, _February 28, 1843_. _To the Senate of the United States_: I transmit to the Senate, for its consideration with a view to ratification, a convention further to provide for the payment of awards in favor of claimants under the convention between the United States and the Mexican Republic of the 11th of April, 1839, signed in the City of Mexico on the 30th day of last month. A copy of the instructions from the Department of State to the minister of the United States at Mexico relative to the convention and of the dispatches of that minister to the Department is also communicated. By adverting to the signatures appended to the original draft of the convention as transmitted from the Department of State to General Thompson it will be seen that the convention as concluded was substantially approved by the representatives of a large majority in value of the parties immediately interested. JOHN TYLER. WASHINGTON, _February 28, 1843_. _To the House of Representatives_: I communicate to the House of Representatives a report from the Secretary of State, which, with the documents[91] accompanying it, furnishes the information requested by their resolution of the 18th instant. JOHN TYLER.
