A similar structure (Fig. 255) at Culsh, in the parish of Tarland in the same county, differs from this one only in being curved to the right instead of to the left. It is 47 feet in length and 2 feet wide at the entrance, the width increasing gradually to about 6 feet at the farther end. The walls are partially formed of large boulders set on end or on edge to form the lower course, with rudely-built masonry over them. They converge but slightly, and the roof is formed in the usual manner by large heavy slabs laid across from wall to wall. The floor is formed of the natural underlying rock, and the height from floor to roof increases from 5 feet near the entrance to an average of about 6 feet farther in. When cleared out in 1853, the earth which filled the chamber was found largely mixed with ashes on the floor, and the only relics obtained from its excavation were fragments of coarse unglazed pottery, a large bead, the bones of cattle, and two querns.

It measures 57 feet in length, 2½ feet wide at the entrance, suddenly widening to about 8 feet at about 20 feet within the entrance. At a short distance from the entrance there were checks for two doors about 8 feet apart. The covering stones had been removed from the first 15 feet of the narrow part, but the roof remained entire over the whole of the wider part of the structure, at an average height of about 6 feet from the floor. The earth with which the chamber was filled was largely mixed with charcoal and bones of animals, among which those of the horse and dog were recognised. No manufactured relics were found, but two of the stones in the walls, one being a large boulder, were covered with the small hemispherical pits known as cup-markings. ----- Footnote 111: _Proc. Soc.
