The leaders of former illegal expeditions of the same character have openly expressed their intention to renew hostilities against Nicaragua. One of them, who has already been twice expelled from Nicaragua, has invited through the public newspapers American citizens to emigrate to that Republic, and has designated Mobile as the place of rendezvous and departure and San Juan del Norte as the port to which they are bound. This person, who has renounced his allegiance to the United States and claims to be President of Nicaragua, has given notice to the collector of the port of Mobile that two or three hundred of these emigrants will be prepared to embark from that port about the middle of November. For these and other good reasons, and for the purpose of saving American citizens who may have been honestly deluded into the belief that they are about to proceed to Nicaragua as peaceful emigrants, if any such there be, from the disastrous consequences to which they will be exposed, I, James Buchanan, President of the United States, have thought it fit to issue this my proclamation, enjoining upon all officers of the Government, civil and military, in their respective spheres, to be vigilant, active, and faithful in suppressing these illegal enterprises and in carrying out their standing instructions to that effect; exhorting all good citizens, by their respect for the laws and their regard for the peace and welfare of the country, to aid the efforts of the public authorities in the discharge of their duties. In testimony whereof I have hereunto set my hand and caused the seal of the United States to be affixed to these presents. [SEAL.] Done at the city of Washington the 30th day of October, 1858, and of the Independence of the United States the eighty-third. JAMES BUCHANAN. By the President: LEWIS CASS, _Secretary of State_. SECOND ANNUAL MESSAGE. WASHINGTON CITY, _December 6, 1858_. _Fellow-Citizens of the Senate and House of Representatives_: When we compare the condition of the country at the present day with what it was one year ago at the meeting of Congress, we have much reason for gratitude to that Almighty Providence which has never failed to interpose for our relief at the most critical periods of our history. One year ago the sectional strife between the North and the South on the dangerous subject of slavery had again become so intense as to threaten the peace and perpetuity of the Confederacy. The application for the admission of Kansas as a State into the Union fostered this unhappy agitation and brought the whole subject once more before Congress. It was the desire of every patriot that such measures of legislation might be adopted as would remove the excitement from the States and confine it to the Territory where it legitimately belonged. Much has been done, I am happy to say, toward the accomplishment of this object during the last session of Congress.
