em charcoal and fragments of
pottery have been found. A brook, dipping under the walls, and passing
through the enclosure, supplied the camp with water.

Drizzlecombe, near Sheep's Tor, is rich in a variety of antiquities, for
it has three stone rows, a large tumulus, a kistvaen, and a later
relic--a miner's blowing-house. One of the avenues is two hundred and
sixty feet long, and one is double for a part of the way, and each of
the three starts from a menhir, or long stone. Near Merivale Bridge are
two double stone rows, but the stones are small. Close by are a sacred
circle, a kistvaen, a pound and hut-circles, and one cairn, besides the
ruins of others that have been destroyed. It would be absurd to pretend
to enter on such a wide subject here. Some idea of its extent may be
gathered by considering one single branch of it: Mr Baring-Gould has
stated that no fewer than fifty stone avenues have been observed in
different parts of the moor. And hut-circles and ancient track-lines are
unnumbered, although very many antiquities of all kinds have been
destroyed when granite was wanted for rebuilding churches, or for making
doorways or gate-posts, or even for mending roads.

The early antiquaries discovered the hand of the Druids in certain
unusual rock-shapes, now known to be the work of Nature--such as
rock-basins, which are developed in the granite by the action of wind
and rain; tolmens, or holed stones; and logans, or rocking-stones.
Granite on the moor generally weathers irregularly, and if the lower
part of a piled-up mass partly crumbles away, a huge layer of harder
granite remains balanced on one or two points, and becomes what is
called a logan-stone. In some cases, though the slab is almost
impossible to remove, it will rock at a finger-touch. Perhaps the most
striking example on Dartmoor is the Rugglestone, near Widdecombe, which
it has been calculated weighs about one hundred and ten tons; but there
are several in the neighbourhood, and a logan called the Nut-Crackers is
perched among the thickly scattered boulders on Lustleigh Cleave. This
lovely little valley lies on the eastern edge of the moor, and the River
Bovey flows through it. Masses of granite crown the ridge; lower on the
hill-side is a jungle of tall bracken, and the stream is overshadowed by
a wood, crowded with matted undergrowth and with innumerable rocks
tumbled together.

Granite more consistent than that found on most of the tors--that is,
