passage, she has made an excellent run. The City
of Washington had arrived at New York.
The Washington Correspondence of the 12th of
October contains the following :
" It is not true, as stated in the despatch to the Herald,
that England has demanded an explanation from our Go-
vernment with reference to the course pursued by General
Harney; on the contrary, the paper submitted by Lord
Lyons was a proposition for a settlement of the dispute, as
the treaty provides no remedy in case of a disagreement be-
tween Boundary Commissioners. The treaty being thus ex-
hausted, the parties are thrown back on first principles, and
England now submits a programme for an adjustment of
the difficulty, in which she claims the island of San Juan.
Secretary Cass has returned his reply to this proposi-
tion, declining in the most positive terms to recognize so
much as the shadow of title on the part of England to the
disputed island. This is the preseut condition of the ques-
tion, and it remainsfor England to take the next step, as we
hold pDssession. This turn in affairs is regarded as very
serious by onr Government, and the result, whether it be
peace or war, depends entirely upon the tenacity with which
Great Britain holds to her pretended claim."
