WASHINGTON, _January 30, 1869_.
_To the Senate of the United States_:
Referring to the Executive communication of the 15th instant, which was
accompanied by a copy of a convention between the United States and
Great Britain providing for the reference to an arbiter of the question
of difference between the United States and Great Britain concerning the
northwest line of water boundary between the United States and the
British possessions in North America, I now transmit to the Senate the
original of that instrument, and a report of the Secretary of State
pointing out the differences between the copy as submitted to the Senate
and the original as signed by the plenipotentiaries.
