Upon every officer, civil or military, and upon every citizen, by the veneration due by all freemen to the laws which they have assisted to enact for their own government, to use every effort in his power to arrest for trial and punishment every offender against the laws providing for the performance of our obligations to the other powers of the world.

I hereby warn all those who have engaged in these criminal enterprises, if persisted in, that, whatever may be the condition to which they may be reduced, they must not expect the interference of this Government in any form on their behalf.

In conformity with the resolution of the Senate, I transmit herewith the report of Major-General Jesup.

To the House of Representatives of the United States: I herewith transmit to the House of Representatives a report from the Secretary of State, together with the documents therein referred to in answer to their resolution of the 28th of May last.

I nominate Lieutenant-Colonel Thayer, of the Corps of Engineers, for the brevet of colonel in the Army, agreeably to the recommendation of the Secretary of War.

In compliance with a resolution passed by the House of Representatives on the 23d instant in respect to the new Treasury building, I submit the inclosed report from the commissioners charged with a general superintendence of the work, and which, with the documents annexed, is believed to contain all the information desired.

With a fixed determination to use all the means in my power to put a speedy and satisfactory termination to these border troubles, I have the most confident assurances of the cordial cooperation of the British authorities, at home and in the North American possessions, in the accomplishment of a purpose so sincerely and earnestly desired by the Governments and people both of the United States and Great Britain.

Every effort has been and will be made to prevent the success of the design, apparently formed and in the course of execution by Canadians who have found a refuge within the territory, aided by a few reckless persons of our own country, to involve the nation in a war with a neighboring and friendly power.

Such design can not succeed while the two Governments appreciate and confidently rely upon the good faith of each other in the performance of their respective duties.

I submit herewith, for consideration and action, a communication from the Secretary of War and the treaty with the Otoe, Missouria, and Omaha Indians therein referred to.

Desiring in this and in all other instances to act with the most cautious respect to the claims of other branches of the Government, I bring this subject to the notice of the Senate that if it shall be deemed proper to raise any question it may be discussed and decided before and not after the power shall have been exercised.
