Mr. Gresham to Mr. Thompson.

[Telegram.]

Mr. Gresham directs Mr. Thompson to transmit promptly a full report of present situation and of events in the city and harbor of Rio de Janeiro, with special reference as to whether there has been any change, and, if so, of what nature and for what reason, in the attitude of the naval forces of the United States towards the Government of Brazil and the insurgents since Capt. Picking was relieved of the command. He inquires whether Admiral Benham disagrees with the other naval commanding officers, and, if so, on what points, and whether the merchant vessels of the United States are now enjoying any protection that was not theretofore accorded by Picking. He also asks as to the nature of his relations with the Brazilian Government and Admiral Benham, and whether a blockade is enforced by the insurgents or any attempt made by them to that end.
