WASHINGTON, _January 15, 1869_.
_To the Senate of the United States_:
I transmit to the Senate, for consideration with a view to its
ratification, a copy of a treaty between the United States and Great
Britain, signed yesterday at London, 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. It is
expected that the original of the convention will be forwarded by the
steamer which leaves Liverpool to-morrow. Circumstances, however, to
which it is unnecessary to advert, in my judgment make it advisable to
communicate to the Senate the copy referred to in advance of the arrival
of the original instrument.
