At Louisville, Ky., a peace meeting, called by prominent secessionists for this evening, was held at the Court House in that city. As the crowd entered the hall, many were singing the Star-Spangled Banner.

A division of the house took place, when Speed was declared elected. The secessionists, about one hundred in number, then withdrew shouting for the Southern Confederacy. Speeches were made by Messrs. Speed, Wolf, Harlan, and others, and resolutions were adopted with but one dissenting voice. The seceders from the meeting reorganized at Concert Hall.

Shotwell were appointed a Committee on Resolutions, who, after retirement, reported a series of resolutions, which were adopted unanimously.--(Doc. 191.)
