Concord (NH) New Hampshire Statesman, "Slave Stampedes," August 30, 1850

SLAVE STAMPEDES. In all the Slave States bordering on the Free States, every now and then there is a regular stampede, or an uprising and fleeing from bondage of a large number of slaves, so many and such extensive ones as to render it certain that in several of the States slavery is on the decrease. Every day adds to the depreciating of slave property in all the exposed States, as its tendency to walk off lessens its value greatly. Slavery is dying out in several of the States.
