78 is the plan of another “twin-barrow,” so called, the circle in the larger being about thirty-five, and the smaller twenty-four, feet in diameter. In the centre, at A B, are the remains of a stone cist, or chamber. “The mounds were both cairns of loose stones. Remains of other barrows, similarly formed, occur in the vicinity. There were two within a few hundred yards of the ‘twin-barrow’ last described, the greater portions of which have recently been taken away to build a neighbouring hedge, but of which I found enough to show how they were built. First, there was an enclosing circle of stones, some placed upright, some longitudinally (fig. 79), the intention being simply to make an enclosing fence; within this the grave was constructed; then small stones heaped over the whole, the cairn extending, by about six feet, outside the built circle.” The more perfect of the “twin-barrows” also had the cairn extending beyond the circle. [Illustration: Fig. 71.] [Illustration: Fig. 72.] [Illustration: Fig. 73.] [Illustration: Fig. 74.] [Illustration: Fig. 75.] [Illustration: Fig. 76.] [Illustration: Fig. 77.] [Illustration: Fig. 78.] [Illustration: Fig. 79.] Some larger circles, such, for instance, as the Bosawen-ûn circle, eighty feet in diameter (fig. 80), the Aber circle (fig. 81), and others, it is supposed, may have been formed around a group of interments, instead of single interments, as in many of the others. In some instances a single stone was placed to mark the place of interment. Three such exist in the barrow at Berriew (fig. 82). A large circle (fig. 83), twenty-seven yards, in diameter, on Penmaenmaur, was constructed of several uprights, connected by smaller masonry. Here the interments were apparently made beside the pillars. Against the inner side of the tallest pillar A, on the eastern part, were the remains of a small stone cist; while against the pillar B, facing it on the opposite side, was heaped up a small cairn. The whole is surrounded by a ditch, within which, at C, is another small cairn. [Illustration: Fig. 80.] [Illustration: Fig. 81.] [Illustration: Fig. 82.] [Illustration: Fig. 83.] Arbor-Low, in the High Peak of Derbyshire, to which allusion has been made, is represented in fig. 84. No sepulchral remains have been discovered within the circle, but barrows of great extent, which have yielded important remains on being excavated, are closely connected with it. It is, however, probable, that interments have existed, and been removed in past ages. [Illustration: Fig. 84.] CHAPTER V.
