The slaves of Maryland are naturally greatly excited by the tumult around them, and are emigrating by whole families and in great numbers into Pennsylvania. It is estimated that not less than 500 have escaped within a few days past. Nothing is more likely to bring the slaveholders to a realizing sense of the nature and tendency of their rebellion than such facts as these, The sudden disappearance of 500 pieces of property, valued at half a million dollars, is a phenomenon calculated to strike even a Plug-Ugly with dismay, especially as it is likely to be followed by much more extensive experiences of the same sort. —New York Tribune (Liberator, May 3, 1861, pg 3)
