BY JAMES BUCHANAN, PRESIDENT OF THE UNITED STATES OF AMERICA. A PROCLAMATION. Whereas the Territory of Utah was settled by certain emigrants from the States and from foreign countries who have for several years past manifested a spirit of insubordination to the Constitution and laws of the United States. The great mass of those settlers, acting under the influence of leaders to whom they seem to have surrendered their judgment, refuse to be controlled by any other authority. They have been often advised to obedience, and these friendly counsels have been answered with defiance. The officers of the Federal Government have been driven from the Territory for no offense but an effort to do their sworn duty; others have been prevented from going there by threats of assassination; judges have been violently interrupted in the performance of their functions, and the records of the courts have been seized and destroyed or concealed. Many other acts of unlawful violence have been perpetrated, and the right to repeat them has been openly claimed by the leading inhabitants, with at least the silent acquiescence of nearly all the others. Their hostility to the lawful government of the country has at length become so violent that no officer bearing a commission from the Chief Magistrate of the Union can enter the Territory or remain there with safety, and all those officers recently appointed have been unable to go to Salt Lake or anywhere else in Utah beyond the immediate power of the Army. Indeed, such is believed to be the condition to which a strange system of terrorism has brought the inhabitants of that region that no one among them could express an opinion favorable to this Government, or even propose to obey its laws, without exposing his life and property to peril.
