The guerrillas Sweeping over Missouri.
Mobile, August 9.
--A special dispatch to the Tribune of this city, dated Grenada, to-day, says: ‘ "The St. Louis Republican, of the 4th says that rebel guerrillas have taken complete possession of Missouri, and are daily growing into a vast army. Nearly thirty thousand of them have crossed the Missouri river, under Porter and Joe Thompson, cleaning out the Home Guards and militia as they progress. They are raising numberless recruits for the Confederate army. Six hundred have turned up at Bird's Point, threatening Cairo, where there is but a small garrison. Gov. Gamble finds it impossible, under the circumstances to get the militia to respond to his call, and has issued another important appeal to them to rally, and complaining of their apathy in the Federal cause."
