_Vincennes, Indiana, April, 1851._ Four fugitive slaves were seized, claimed by one Mr. Kirwan, of or near Florence, Alabama. The magistrate, named Robinson, gave up the fugitives, and they were taken into slavery. _In Salisbury Township, Penn., April, 1851_, an elderly man was kidnapped and carried into Maryland. _Near Sandy Hill, Chester County, Penn., in March, 1851_, a very worthy and estimable colored man, named Thomas Hall, was forcibly seized, his house being broken into by three armed ruffians, who beat him and his wife with clubs. He was kidnapped. MOSES JOHNSON, _Chicago, Illinois_, brought before a United States Commissioner, discharged as not answering to the description of the man claimed. CHARLES WEDLEY, kidnapped from _Pittsburg, Pennsylvania_, and taken into Maryland. He was found, and brought back. _Cincinnati, Ohio, June 3, 1851_, an attempt to arrest a fugitive was made. But a scuffle ensued, in which the man escaped. _Cincinnati, Ohio._ About the same time, some slaves, (number not stated,) belonging to Rev. Mr. Perry and others, of Covington, Kentucky, were taken in Cincinnati, and carried back to Kentucky. _Philadelphia, end of June, 1851_, a colored man was taken away as a slave, by steamboat. A writ of _Habeas Corpus_ was got out but the officer could not find the man. This is probably the same case with that of JESSE WHITMAN, arrested at Wilkesbarre. FRANK JACKSON, a free colored man in _Mercer, Penn._, was taken, early in 1851, by a man named Charles May, into Virginia, and sold as a slave. He tried to escape, but was taken and lodged in Fincastle jail, Virginia. THOMAS SCOTT JOHNSON, free colored man, of _New Bedford_, was arrested near Portsmouth, Virginia, and was about to be sold as a slave; but, by the strenuous interposition of Capt. Card, certificates were obtained from New Bedford, and he was set at liberty. ELIZABETH WILLIAMS, _West Chester County, Penn._, delivered into slavery by Commissioner Jones. (July, 1851.) DANIEL HAWKINS, of _Lancaster County, Penn._, (July, 1851,) was brought before Commissioner Ingraham, Philadelphia, and by him delivered to his claimant, and he was taken into slavery. _New Athens, Ohio, July 8, 1851._ Eighteen slaves, who had escaped from Lewis County, Kentucky, were discovered in an old building in Adams County, Ohio. Some white men, professing to be friendly, misled them, and brought them to a house, where they were imprisoned, bound one by one, and carried back to Kentucky. [The enactment of the Fugitive Slave Law is the direct stimulating cause of all these cases of kidnapping.]
