As I have previously observed, striated boulders, brought from a great distane by what geologists term the “glacial drift,” are especially regarded as debris resulting from giant warfare or amusement. Many rocks of this class lying to the south of Pendle Hill, near Great Harwood, I am informed, are still looked upon by the vulgar as stones which have been hurled by giants from the surrounding hills.
