Casgliadau Arlein

A single fragment comprising approximately 28 per cent of an upper stone which has a thickness varying between 92 and 81 mm. at the circumference, and an estimated diameter of 0.36m. A narrow margin circumscribes the upper surface, and confines a spacious, convex hopper, which has an estimated diameter of 0.26m.The section of an 'elbow-shaped' perforation is incised upon one fracture of the fragment, while the thickness of the stone contracts to a mere 29 mm. at the fracture near the bottom of the hopper. The upper surface and the gently convex, outward-splaying sides are carefully dressed with pockmarks. The depressed, slightly concave grinding face is similarly treated, and although each part exhibits signs of rubbing, the maximum wear has occurred about the skirt, where a single concentric striation is also etched upon the surface. The fragment has suffered some rough, treatment in the course of its working life, and is chipped about the sides.
