Until a recent period there was good reason to believe that I should be able to announce to you on the present occasion that our difficulties with Great Britain arising out of the Clayton and Bulwer treaty had been finally adjusted in a manner alike honorable and satisfactory to both parties.  From causes, however, which the British Government had not anticipated, they have not yet completed treaty arrangements with the Republics of Honduras and Nicaragua, in pursuance of the understanding between the two Governments.  It is, nevertheless, confidently expected that this good work will ere long be accomplished.

Whilst indulging the hope that no other subject remained which could disturb the good understanding between the two countries, the question arising out of the adverse claims of the parties to the island of San Juan, under the Oregon treaty of the 15th June, 1846, suddenly assumed a threatening prominence.  In order to prevent unfortunate collisions on that remote frontier, the late Secretary of State, on the 17th July, 1855, addressed a note to Mr. Crampton, then British minister at Washington, communicating to him a copy of the instructions which he (Mr. Marcy) had given on the 14th July to Governor Stevens, of Washington Territory, having a special reference to an “apprehended conflict between our citizens and the British subjects on the island of San Juan.”  To prevent this the governor was instructed “that the officers of the Territory should abstain from all acts on the disputed grounds which are calculated to provoke any conflicts, so far as it can be done without implying the concession to the authorities of Great Britain of an exclusive right over the premises.  The title ought to be settled before either party should attempt to exclude the other by force or exercise complete and exclusive sovereign rights within the fairly disputed limits.”

In acknowledging the receipt on the next day of Mr. Marcy’s note the British minister expressed his entire concurrence “in the propriety of the course recommended to the governor of Washington Territory by your [Mr. Marcy’s] instructions to that officer,” and stating that he had “lost no time in transmitting a copy of that document to the Governor-General of British North America” and had “earnestly recommended to His Excellency to take such measures as to him may appear best calculated to secure on the part of the British local authorities and the inhabitants of the neighborhood of the line in question the exercise of the same spirit of forbearance which is inculcated by you [Mr. Marcy] on the authorities and citizens of the United States.”
