COLUMBIA, S.C. — On the campus of Mr. Jefferson’s university in Charlottesville, Va., it is said that ghost dogs stalk the old football field. The dogs were named Seal and Beta, and they were campus mascots 20 years apart. Seal was the dog of the walk in the 1930s, until he got hit by a car, and then they gave him a funeral procession through the campus. In the 1950s, there was Seal, who died from somewhat more natural causes but also was widely mourned. The two of them are buried just outside the fenceline of the university’s cemetery, but it is said that both of them can be seen wandering the grounds of old Lambeth Field.
