such proper judicial tribunals as may commend themselves to the Western
powers for the trial of causes to which foreigners are parties, and to
assimilate the terms and duration of its treaties to those of other

Through our ministers at London and at Monrovia this Government has

the northwestern boundary of that Republic. There is a prospect of
adjustment of the dispute by the adoption of the Mannah River as the

I have alluded in my previous messages to the injurious and vexatious
restrictions suffered by our trade in the Spanish West Indies, Brazil,
whose natural outlet for its great national staple, coffee, is in and
