[Illustration: Fig. 145.—Ornamented Stone Ball found at Fordoun, Kincardineshire (2¾ inches in diameter).] A ball of fine-grained clay slate (Fig. 144) found at Freelands, near Glasterlaw, Forfarshire, has six projecting discs of slight convexity arranged upon its surface; but the discs are small in proportion to the size of the ball and the interspaces wide. The discs themselves are plain, but the interspaces are partially ornamented. In the space between three contiguous discs is a pattern composed of three triangular figures within each other, formed by the meeting of curved or segmental lines. In the next contiguous space is a double spiral. A ball of fine-grained dark-coloured sandstone (Fig. 145), found at Fordoun, in Kincardineshire, has its surface divided into seven circular compartments, some of which are simply incised with concentric circles, while in others there is a border of chevrony ornament enclosing the concentric circles. [Illustration: Fig. 146.—Ornamented Stone Ball, in the collection of Sir J. Noel Paton (2¾ inches in diameter).] An example in the collection of Sir J. Noel Paton (Fig. 146) presents a different style of ornament. It is of hornblendic schist, 2¾ inches in diameter, and has its surface divided into six projecting discs, carved with concentric bands of slight convexity, the bands increasing in width and prominence towards the centre of the disc. The spaces between the discs are ornamented by irregular scoopings of the surface as if with the point of a gouge-like tool—a variety of decoration also seen in the gold object found on Cairnmuir (Fig. 114). [Illustration: Fig. 147.—Ornamented Stone Ball found at Ballater, Aberdeenshire (2⅞ inches in diameter).] On the top of Craig Beg, near Ballater, previous to 1864, three stone cists were found containing interments which, from the presence of ashes and bones, were assigned to the Pagan custom of cremation. Each cist was also surrounded by a number of boulder-stones arranged in a circle of about 15 feet in diameter. Close to one of these cists a stone ball (Fig. 147) was found, having its surface divided into six circular discs of slight convexity, and some of the interspaces between the discs ornamented with small, rounded, slightly projecting knobs.
