There is a very remarkable tumulus a few 100 yards south of the Long Stone, which on being opened in the year 1870 was found to contain a sepulchral chamber 8 feet long, 4 feet wide, and 5 feet 6 inches high, with an entrance porch 3 feet square and covered by a massive stone 9 feet 6 inches long and 5 feet 6 inches wide. In this sepulchral chamber was found a skeleton in a sitting position at the furthest end.
