The main entrance to these enclosures is on the south. The mural huts are placed at the north-west angle of the west court and the south-west angle of the south court. The first is the most interesting; it is contained in a small rectangular block of masonry filling up the angle, and the plan of the chamber itself is that of a joiner's square. There is no trace left of any covering to these huts, but they were probably covered with stone flags or branches of trees. Within and without the enclosures are cairns of all sizes, one of which is known as The Giant's Grave. It is remarkable that all the settlements in the Furness district are found on the fells, and never in the dales, some of them being 300 feet above the sea-level. Of any actual defensive structure there is no trace. The settlers here evidently buried their dead close to their homes, and from the calcined bones found it is clear that the bodies were burnt. These earthen burial-mounds are, however, very scarce in the district; rude-stone cists have been unearthed, but no trace of metals or ornamental workmanship except a few pieces of rude pottery. At Holme Bank, Urswick, the rampart of earthed stones encloses a five-sided figure, within which are traces of cross walls, the general plan of which points to the site of an early settlement. The rampart or entrenchment discovered at Hawkeshead Park is of a similar character. At Scrow Moss, near the foot of Coniston Old Man, is another of these enclosures, a drawing of which is given in _Archæologia_ (vol. liii., part 2). At Dunnerdale Fell is an enclosure very similar to that found at Heathwaite, though much smaller, the central homestead being formed by a single wall, near to which are several cairns and remains of walls. On Birkrigg Common, at a place called Appleby Slack, is another of these small enclosures, consisting of a single rampart or vallum of earth, enclosing a pear-shaped area, not far from which is a tumulus, and about half a mile to the south-east is a double concentric stone circle. Concerning these various remains in the Furness district, the writer of the exhaustive article in _Archæologia_[5] just referred to is of opinion that their elevated position is due to the fact that the lower ground was at that period such a dense mass of scrub and jungle that it was utterly untenable for residential purposes. These various enclosures do not appear to have been forts, as the homesteads themselves were all on the sloping sides of the hills, but were rather the dwelling-places of a very early tribe of settlers, who were living at peace with their neighbours, and had, therefore, no need of a system of defence, such as we find traces of in other parts of the county. The plan of these settlements was simple--the smaller courts were the living apartments, and were no doubt covered with some kind of roof; the larger enclosures were for the cattle, or possibly for the lower orders of the tribes who held the place.
