Kits Cotty House, in Kent; the Chun cromlech, in Cornwall (figs. 39 and 40)--the covering stone of which is calculated to weigh twenty tons; the Molfra cromlech, in the same county, which consists of a compact cist closed on three sides and open on the fourth; the Zenor cromlech; the Plas Newydd cromlech, and many others which it is not necessary to enumerate, are all of the same class. The Plas Newydd (fig. 41) is a double cromlech, the two chambers being close together, end to end. The capstone of the largest, which is about twelve feet in length by ten feet in breadth, originally rested on seven stones, two of which have disappeared. The two erections undoubtedly were originally covered with a single mound. [Illustration: Fig. 41.] At Minninglow, in Derbyshire, erections of this kind occur, but, not being denuded of their mounds, are still partially buried. The mound is of large size. Under the centre and in four places in the area of the circle are large cists, which if cleared from the earth would be fine cromlechs of precisely the same form as those just described. They are formed of large slabs of the limestone of the district, placed upright on the ground, and are covered with immense capstones of the same material. All these chambers had contained interments. The accompanying plan (fig. 42) of some of these cists gives the situation of the stones forming the sides of the large chamber; of the passage leading to it; of the slabs which closed its entrance; and of the covers or capstones. The chamber is rather more than five feet in height, and the largest capstone about seven feet square, and of great thickness. A kind of wall similar to those which have been found to encircle some of the Etruscan tumuli, forms the circle of this mound, which rises to a height of more than fifteen feet from the surface of the ground.[17] [Illustration: Fig. 42.] The general arrangement of this example will be seen to bear an analogy to the Plas Newydd and others spoken of, and shows by what an easy transition the building of galleries, or a series of chambers for family tombs, in these large mounds, would be arrived at. Of this kind some very large examples exist in Ireland, and in the Channel Islands, as well as in various parts of England. [Illustration: Fig. 43.]
