I have the satisfaction to state that the proposal was received by the British Government in the spirit which prompted it, and that a negotiation has been opened at London embracing all these objects.  On full consideration of the great extent and magnitude of the trust it was thought proper to commit it to not less than two of our distinguished citizens, and in consequence the envoy extraordinary and minister plenipotentiary of the United States at Paris has been associated with our envoy extraordinary and minister plenipotentiary at London, to both of whom corresponding instructions have been given, and they are now engaged in the discharge of its duties.  It is proper to add that to prevent any inconvenience resulting from the delay incident to a negotiation on so many important subjects it was agreed before entering on it that the existing convention should be continued for a term not less than eight years.

Our relations with Spain remain nearly in the state in which they were at the close of the last session.  The convention of 1802, providing for the adjustment of a certain portion of the claims of our citizens for injuries sustained by spoliation, and so long suspended by the Spanish Government, has at length been ratified by it, but no arrangement has yet been made for the payment of another portion of like claims, not less extensive or well founded, or for other classes of claims, or for the settlement of boundaries.  These subjects have again been brought under consideration in both countries, but no agreement has been entered into respecting them.

In the mean time events have occurred which clearly prove the ill effect of the policy which that Government has so long pursued on the friendly relations of the two countries, which it is presumed is at least of as much importance to Spain as to the United States to maintain.  A state of things has existed in the Floridas the tendency of which has been obvious to all who have paid the slightest attention to the progress of affairs in that quarter.  Throughout the whole of those Provinces to which the Spanish title extends the Government of Spain has scarcely been felt.  Its authority has been confined almost exclusively to the walls of Pensacola and St. Augustine, within which only small garrisons have been maintained.  Adventurers from every country, fugitives from justice, and absconding slaves have found an asylum there.  Several tribes of Indians, strong in the number of their warriors, remarkable for their ferocity, and whose settlements extend to our limits, inhabit those Provinces.

These different hordes of people, connected together, disregarding on the one side the authority of Spain, and protected on the other by an imaginary line which separates Florida from the United States, have violated our laws prohibiting the introduction of slaves, have practiced various frauds on our revenue, and committed every kind of outrage on our peaceable citizens which their proximity to us enabled them to perpetrate.
