A winding, up-hill lane conducts us in about two miles to the first genuine piece of moorland – Winsford Hill. Between the finger-post marking the cross-roads and the hedge on the right, and at the side of an old track -- I believe the former highway -- is a rude standing stone of hard slaty rock, known as the Longstone. It leans considerably out of the perpendicular, and has met with rough usage, a portion of the top having been broken off. The height is 3 feet 7 inches, the breadth 14 inches, and the thickness 7 inches. It is inscribed lengthwise with characters, but of what age or date I am unable to decide. That they have been there for many centuries, there can, I think, be no doubt, their worn appearance testifying to many an onslaught of the elements. The aforesaid fracture, the work of a mischievous youth but a few months back, has probably obliterated a part of the second line, and although I was able to find the splintered fragment, and fit it into its place, it availed me not, as the surface had flaked off. I read the inscription thus: CVRAACI FPVS. The first word apprently stands for ‘(son) of Curatacus,’ evidently the Latinized form of some British name. This is the only interpretation I can offer. The local legend says that it marks a deposit of treasure; but it is somewhat strange that there are no traces about the stone indicating that a search has been made.
