“To you, Sir, to a very considerable degree, we owe the recognition of the Republic of Liberia by the Government of the United States. “Had it not been for your masterly policy and your wise discretion, allied to a most persistent determination, we have reason to doubt whether the Bill of Recognition would not have met with a miscarriage during the present session of Congress. “Thanks to your fast friendship, it has not failed, and the Republic of Liberia has been brought, through wise and cordial legislation, into brotherhood with the great Republic of America.

As Mr. Sumner felt it his duty to decline the medal, the Haytien Minister placed it in the hands of the Governor of Massachusetts, who deposited it in the Library of the State-House.
