COVERED CHAMBER AND COOKING-HOLE.

Connected with the camp on the north-east is a ruined wall that leads to an inclosure with numerous hut circles. South-west of the camp further down the hill is a pound in good preservation with eight hut circles in it. A reeve or bank to the west of the camp leads down to other collections of habitations of the same description.

CONSTRUCTION OF STONE AND TIMBER WALL.

Some ten cairns on the slopes have been investigated, but have yielded little beyond the handful of ashes sunk in a pit in the centre that represents the dead. A ruined kistvaen, much mutilated, lies between the camp and the Langstone, a menhir that gives its name to the common, and which is the starting-point of a stone row of very inconsiderable blocks that led to a cairn now demolished, and its place occupied by a pool. From Langstone a track to the south-east leads by the head of the Peter Tavy stream, which rises in a bog, to a fine circle of standing stones, and on the slope below that and above the Walkham river is a large settlement of some thirty or forty habitations. Beyond the Peter Tavy brook, moreover, are numerous clusters of dwellings. To all the population who lived in these huts, Whit Tor had served as a camp of refuge. The place deserves a visit, for we have there collected within a small radius the houses and hamlets occupied by the primeval race, the tombs of their dead, the stone row set up in memory of some chief represented by the Longstone towering above the petty stones below, the circle in which the dead were burned, and finally, the camp to which they flew to defend their beloved moor from invasion.

It may cause some surprise that the walls of the stone castles should be in such complete ruin. But, in all likelihood, they were constructed on the same principle as the Gaulish camps described by Cæsar. They were built of timber frames packed in with stones, and the logs mortised together held the stones in place. When, however, the wood rotted, this mode of construction ensured and precipitated utter ruin. At Murcens, in the department of Lot, is one of these stone camps, and sufficiently well preserved, owing to the size of the limestone slabs employed in the building, to show precisely how the whole was constructed. But the walls of Iosolodunum, that held out so bravely against Cæsar, being built of small stones compacted with timber, are now but heaps of ruin, no better than those of Whit Tor.

Brent Tor was fortified in a manner very similar to Whit Tor; the outer wall remains fairly perfect on the north side, but the inner wall has been much injured. In this instance it is not the summit, but the base of the hill that has been defended. As there is a church on the summit, as also a churchyard with its wall, these have drawn their supplies from the circumvallation. Moreover, it has been broken through to form a way up to the church.
