A similar condition exists in regard to the treaty between the United States and the Oriental Republic of Uruguay of the 28th August, 1852. The Senate, by a resolution of 13th June, 1854, extended the time within which the ratifications of that treaty might be exchanged to thirty months from its date. That limit, however, has expired, and the exchange has not been effected. I deem it expedient to direct a renewal of negotiations with the Governments referred to, with a view to secure the exchange of the ratifications of these important conventions. But as the limit prescribed by the Senate in both cases has passed by, it is necessary that authority be conferred on the Executive for that purpose. I consequently recommend that the Senate sanction an exchange of the ratifications of the treaties above mentioned at any time which may be deemed expedient by the President within three years from the date of the resolution to that effect.

FRANKLIN PIERCE. EXECUTIVE OFFICE, _August 4, 1856_. _To the Senate of the United States_: I communicate herewith a report of the Secretary of War, in response to a resolution of the Senate calling for information in relation to instructions "issued to any military officer in command in Kansas to disperse any unarmed meeting of the people of that Territory, or to prevent by military power any assemblage of the people of that Territory." FRANKLIN PIERCE.
