To the Senate:
In conformity with a resolution of the Senate of the 31st December last, I herewith transmit copies of the instructions under which the late treaty of indemnity with Naples was negotiated, and of all the correspondence relative thereto.
It will appear evident from a perusal of some of those documents that they are written by the agents of the United States to their own Government with a freedom, as far as relates to the officers of that of Naples, which was never intended for the public eye, and as they might, if printed, accidentally find their way abroad and thereby embarrass our ministers in their future operations in foreign countries, I respectfully recommend that in the printing, if deemed necessary, such a discrimination be made as to avoid that inconvenience, preferring this course to withholding from the Senate any part of the correspondence.
