On Sunday night nine slaves escaped form their owners in Boone county. They were, Lewis, about 24 years of age; Susan, 39 years of age; Wesley, 6 years of age; John, 7 years of age; Almeda, 26 years of age, and Sarah Jane, 3 years of age; belonging to Mr. Wm. Walton. Shadrach, 60 years of age, to Mr. Jonas Christler; Anderson, to Mr. John P. Scott; and Lee, to the heirs of Wm. H. Blankenbeker. They crossed the river in a skiff and landed in Indiana, the proceeded to within five miles of Cincinnati, where they concealed themselves, awaiting to go to Canada. Information of their whereabouts reaching the owners, pursuit was made, and with the assistance of deputy marshals Lee Worley, of Cincinnati, and deputy sheriff Ward, of Covington, all were arrested Wednesday night. On Thursday they were taken before JOHN S. PENDERY, U. S. Commissioner, at his office in Court street, where the investigation is now going on. Messrs. KETCHUM and PUGH, of Cincinnati, and DUDLEY, of Covington, are attorneys for the claimants, and Messrs. GITCHELL and JOLIFFE for the negroes. There seems to be no doubt that the fugitives will be returned to their owners. The Columbian says:

     'The general impression is, that the whole party will be returned to their alleged owners. It is reported that twenty-seven slaves in all escaped from Grant and Boone counties, Ky., on last Sunday, but no trace has been discovered of eighteen of them. There is no excitement in relation to the return of those caught, as the owners seem very unassuming, plain Kentucky farmers, who have treated their slaves with general kindness and propriety.'
