The general features of the Cornish group, on the other hand, are more allied to those of the Scottish area, inasmuch as they are often associated with clusters of overground habitations. One at Chapel Euny, in the parish of Saucreed, near Penzance, contiguous to the sites of four circular huts, is an underground gallery presenting features of remarkable similarity to that at Cairn Conan, in Forfarshire. The gallery, which is slightly curved, is about 60 feet in length, 6 feet wide, and from 6 to 7 feet high. A circular chamber, 16 feet in diameter, constructed of large granite blocks, each overlapping the one below it and thus forming a domed roof which must have been 10 or 12 feet high, was connected with the wider end of the gallery by a passage 10 feet long, opening off one side. Another small offset near the narrower end of the gallery, also about 10 feet long, slopes up to the surface, presenting an entrance doorway 2 feet 8 inches in height, with recesses on either side as if to retain a slab to close the doorway. The floors of the gallery and chamber were paved with flat stones, and provided with drains underneath the pavement. The relics found in the structure were whetstones; hammer-stones; spindle-whorls; several varieties of domestic pottery, red and black, mostly plain, but occasionally ornamented with markings made by a pointed instrument; an iron spear-head; and a fragment of the red lustrous ware commonly called Samian.[118] Another at Halligey, near Trelowarren, consists of a slightly-curved gallery 90 feet in length, from 3 to 5 feet in width, and about 6 feet high in the middle, becoming lower towards the extremities. It has a small rectangular chamber off one side at the farther end of the main gallery. The main gallery opens off the middle of the side of a shorter and wider gallery 28 feet in length, 5½ feet wide, and 6 feet high. At one end of this shorter gallery a narrow passage rises to the surface. The entrance passage is provided with checks for two doors, and the whole structure is strongly and substantially built and lintelled with large flags. On the surface there are traces of two embankments with an intervening ditch surrounding a large area within which there may have been a cluster of overground structures.[119] ----- Footnote 118: These details are taken from a paper by William Borlase, Esq., in the _Proceedings of the Society of Antiquaries of London_, 1868 (Second Series, vol. iv. p. 161), where a ground plan and sections, with woodcuts of the structural appearance of the building are given.
