convention or treaty to carry out the views of Her Majesty’s Government in relation thereto, and that the proposition for such a convention or treaty was declined on the part of the American Government for reasons which are fully set forth in the note of the Secretary of State to Mr. Crampton of the 26th of June last.  During the negotiations connected with this correspondence, not considering the markets of Canada as an equivalent for those of the United States, I directed the Secretary of State to inquire what other benefits of trade and commerce would be yielded by the British authorities in connection with such a measure, and particularly whether the free navigation of the St. Lawrence would be conceded to us.  That subject has accordingly been presented to the British Government, and the result was communicated by Her Majesty’s minister in Washington on the 27th of March last in reply to a note from the Secretary of State of the 26th of that month.  From these papers it will be perceived that the navigation of the St. Lawrence and of the canals connecting it with the Western lakes will be opened to the citizens of the United States in the event that the bill referred to in the correspondence, providing for the admission of their natural products, should become a law.  The whole subject is now submitted to the consideration of Congress, and especially whether the concession proposed by Great Britain is an equivalent for the reciprocity desired by her.

To the Senate of the United States:

With reference to the convention between the United States and Her Britannic Majesty relative to interoceanic communication by the way of Nicaragua, recently submitted to the Senate, I transmit a copy of a note, under date the 29th ultimo, addressed to the Secretary of State by Sir Henry L. Bulwer, Her Britannic Majesty’s minister here, and of Mr. Clayton’s reply, under date the 30th ultimo.  Intelligence received from the charge d’affaires of the United States in Central America and from other quarters having led to an apprehension that Mr. Chatfield, Her Britannic Majesty’s minister in that country, had concluded a treaty with the Government of Costa Rica placing that State under the protection of the British Government, I deemed it my duty to cause inquiries upon the subject to be addressed to Her Majesty’s Government through Sir Henry L. Bulwer.  The note of that functionary communicates the answer to those inquiries, and may be deemed satisfactory, both from the denial of the fact that any such treaty has been concluded and from its positive disavowal on behalf of the British Government of the policy intended to be subserved by such treaties.
