The wall itself is double-faced, and the two faces have fallen inwards. This shows that the core could not have been of turf, as in that case shrubs would have rooted themselves therein and have thrust the walls outward. In several places openings appear from the inside of the pound into the space between the walls. It is possible that this intermediate hollow was used for stores, and that the walls were tied together with timber, and surmounted with a parapet of turf. A trackway from Manaton to Headland Warren runs through the pound, and the wall has been broken through for this purpose in two places; but the original entrance to the S.S.E. is perfect, and is paved, and in it three steps have been formed, as the descent was into the pound, another token that the inclosure was not intended as a fortress. The entrance is 8 feet wide, and no outwork was constructed to protect it from being "rushed" by an enemy. The walls of the inclosure here and throughout are from 10 feet to 12 feet thick, and stone does not exist in any part which could raise them above 5 feet 6 inches in height. Each wall is 3 feet 6 inches wide at base, and was 3 feet at top. On the west side is a huge slab set on edge, measuring 10 feet by 5 feet, and it is from 9 inches to 1 foot in thickness, and weighs from 3 to 4 tons. Other stones, laid in courses, if not so long, are not of less weight. Such a wall as that inclosing Grimspound would cost, with modern appliances and with horse power for drawing the stone, three guineas per land yard, and a land yard would engage four men for a week. When, moreover, we consider that the circumference of the wall measures over 1,500 feet, it becomes obvious that a large body of men must have been engaged in the erection. [Illustration: GRIMSPOUND] Presumably Grimspound was not a fortified village, and was merely a pound into which cattle were driven for protection against wolves. It is just possible, but hardly probable, that it was the place of refuge for the scattered population on Hookner and Hamildon. Within the pound are twenty-four hut circles; most have been explored, and one (No. III. on the plan) has been partially restored, and is inclosed within a railing. The object of this restoration was to discover, by piling up the stones found in and about the wall of the hut, what its height had been originally, and this was determined to have been four feet. Unless wantonly injured by trippers, it will serve to exhibit what the structure of these habitations was, with its paved platform as bed, and its hearth and vestibule. A double hut (XVIII., XIX.) is interesting because a tall stone was erected beside it, as though to indicate it as being the residence of some man of importance, maybe the sheik of the community. In hut XVI. is a double bed, one couch divided from the other by upright stones.
