In answer to the resolution of the Senate of the 23d ultimo, requesting information in regard to the fisheries on the coasts of the British possessions in North America, I transmit a report from the Acting Secretary of State and the documents by which it was accompanied.  Commodore M.C.  Perry, with the United States steam frigate Mississippi under his command, has been dispatched to that quarter for the purpose of protecting the rights of American fishermen under the convention of 1818.

To the House of Representatives of the United States: 

I transmit a report from the Acting Secretary of State and the documents by which it was accompanied, in answer to a resolution of the House of Representatives of the 22d ultimo, on the subject of the fisheries, and state for the information of that House that the United States steam frigate Mississippi has been dispatched to the fishing grounds on the coasts of the British possessions in North America for the purpose of protecting the rights of American fishermen under the convention between the United States and Great Britain of the 20th of October, 1818.

WASHINGTON, August 10, 1852.

To the Senate of the United States: 

I transmit a copy of the certificate of the exchange of the ratifications of the general convention of peace, amity, commerce, and navigation between the United States and the Republic of San Salvador, signed at Leon, in Nicaragua, on the 2d of January, 1850.  It will be seen that the exchange was not effected until the 2d of June last, but that it was stipulated that the convention was not to be binding upon either of the parties thereto until the Senate of the United States should have duly sanctioned the exchange.

The Senate by its resolution of the 27th of September, 1850, authorized the exchange to take place at any time prior to the 1st of April, 1851.

Mr. Kerr, the charge d’affaires of the United States to Nicaragua, however, who was authorized to make the exchange on the part of this Government, was unavoidably detained in that Republic, in consequence of which the exchange could not be effected within the period referred to.

The expediency of sanctioning the exchange which has been made by Mr. Kerr, and of authorizing the convention to go into effect, is accordingly submitted to the consideration of the Senate.
