Washington (DC) Union, "Stampede of Slaves," April 13, 1858

   STAMPEDE OF SLAVES.––From information which has reached us, says the Baltimore Sun, there would seem to have been a considerable stampede of slaves from the border valley counties of Virginia during the late Easter holidays. We have heard of seven having made their escape from the plantation of Mr. Mason, in Loudon county, near the Point of Rocks, and two from Berkeley county. It is supposed others have also gone.
