This Government consented to restrictions in regard to a region of country wherein we had specific and peculiar interests only upon the conviction that the like restrictions were in the same sense obligatory on Great Britain. But for this understanding of the force and effect of the convention it would never have been concluded by us.
So clear was this understanding on the part of the United States that in correspondence contemporaneous with the ratification of the convention it was distinctly expressed that the mutual covenants of nonoccupation were not intended to apply to the British establishment at the Balize. This qualification is to be ascribed to the fact that, in virtue of successive treaties with previous sovereigns of the country, Great Britain had obtained a concession of the right to cut mahogany or dyewoods at the Balize, but with positive exclusion of all domain or sovereignty; and thus it confirms the natural construction and understood import of the treaty as to all the rest of the region to which the stipulations applied.
It, however, became apparent at an early day after entering upon the discharge of my present functions that Great Britain still continued in the exercise or assertion of large authority in all that part of Central America commonly called the Mosquito Coast, and covering the entire length of the State of Nicaragua and a part of Costa Rica; that she regarded the Balize as her absolute domain and was gradually extending its limits at the expense of the State of Honduras, and, that she had formally colonized a considerable insular group known as the Bay Islands, and belonging of right to that State.
All these acts or pretensions of Great Britain, being contrary to the rights of the States of Central America and to the manifest tenor of her stipulations with the United States as understood by this Government, have been made the subject of negotiation through the American minister in London. I transmit herewith the instructions to him on the subject and the correspondence between him and the British secretary for foreign affairs, by which you will perceive that the two Governments differ widely and irreconcilably as to the construction of the convention and its effect on their respective relations to Central America.
Great Britain so construes the convention as to maintain unchanged all her previous pretensions over the Mosquito Coast and in different parts of Central America. These pretensions as to the Mosquito Coast are founded on the assumption of political relation between Great Britain and the remnant of a tribe of Indians on that coast, entered into at a time when the whole country was a colonial possession of Spain. It can not be successfully controverted that by the public law of Europe and America no possible act of such Indians or their predecessors could confer on Great Britain any political rights.
Great Britain does not allege the assent of Spain as the origin of her claims on the Mosquito Coast. She has, on the contrary, by repeated and successive treaties renounced and relinquished all pretensions of her own and recognized the full and sovereign rights of Spain in the most unequivocal terms. Yet these pretensions, so without solid foundation in the beginning and thus repeatedly abjured, were at a recent period revived by Great Britain against the Central American States, the legitimate successors to all the ancient jurisdiction of Spain in that region. They were first applied only to a defined part of the coast of Nicaragua, afterwards to the whole of its Atlantic coast, and lastly to a part of the coast of Costa Rica, and they are now reasserted to this extent notwithstanding engagements to the United States.
On the eastern coast of Nicaragua and Costa Rica the interference of Great Britain, though exerted at one time in the form of military occupation of the port of San Juan del Norte, then in the peaceful possession of the appropriate authorities of the Central American States, is now presented by her as the rightful exercise of a protectorship over the Mosquito tribe of Indians.
But the establishment at the Balize, now reaching far beyond its treaty limits into the State of Honduras, and that of the Bay Islands, appertaining of right to the same State, are as distinctly colonial governments as those of Jamaica or Canada, and therefore contrary to the very letter, as well as the spirit, of the convention with the United States as it was at the time of ratification and now is understood by this Government.
The interpretation which the British Government thus, in assertion and act, persists in ascribing to the convention entirely changes its character. While it holds us to all our obligations, it in a great measure releases Great Britain from those which constituted the consideration of this Government for entering into the convention. It is impossible, in my judgment, for the United States to acquiesce in such a construction of the respective relations of the two Governments to Central America.
To a renewed call by this Government upon Great Britain to abide by and Carry into effect the stipulations of the convention according to its obvious import by withdrawing from the possession or colonization of portions of the Central American States of Honduras, Nicaragua, and Costa Rica, the British Government has at length replied, affirming that the operation of the treaty is prospective only and did not require Great Britain to abandon or contract any possessions held by her in Central America at the date of its conclusion.
