It may perhaps be thought slightly suggestive of a tradition of public ceremonies having been performed at this place that, when a wedding occurs in the neighbourhood, the miners repair to these stones, and, having drilled a hole or holes, load them with powder, and fire them instead of cannons. Accidents frequently happen on these occasions, but it is satisfactory to know that the miners suffer from them more than the stones do; the latter are, however, full of the holes made in this manner, which must not be mistaken for ancient markings or wedge holes.
