ty to
give the notice for the abrogation of the convention of 1827 the Senate
acted publicly so large a part that a decision on the proposal now made
by the British Government, without a definite knowledge of the views of
that body in reference to it, might render the question still more
complicated and difficult of adjustment. For these reasons I invite the
consideration of the Senate to the proposal of the British Government
for the settlement of the Oregon question, and ask their advice on the
subject.

My opinions and my action on the Oregon question were fully made known
to Congress in my annual message of the 2d of December last, and the
opinions therein expressed remain unchanged.

Should the Senate, by the constitutional majority required for the
ratification of treaties, advise the acceptance of this proposition, or
advise it with such modifications as they may upon full deliberation
deem proper, I shall conform my action to their advice. Should the
Senate, however, decline by such constitutional majority to give such
advice or to express an opinion on the subject, I shall consider it my
duty to reject the offer.

I also communicate herewith an extract from a dispatch of the Secretary
of State to the minister of the United States at London under date of
the 28th of April last, directing him, in accordance with the joint
resolution of Congress "concerning the Oregon Territory," to deliver the
notice to the British Government for the abrogation of the convention of
the 6th of August, 1827, and also a copy of the notice transmitted to
him for that purpose, together with extracts from a dispatch of that
minister to the Secretary of State bearing date on the 18th day of May
last.

I transmit herewith a communication from the Secretary of War, which is
accompanied by documents relating to General Gaines's calls for

Senate of the 5th instant on that subject, and which I deem it proper to
