3. The stone circle is called by the French a cromlech. The name means curved stone. The circle, of which Stonehenge is the noblest known example in Europe, consists of a number of stones set up at intervals in a ring. The purport is purely conjectural. Undoubtedly interments have been made within them; but none, so far, have been found in those on Dartmoor. In the great circle on Penmaen-mawr there were burials at the foot of several of the monoliths, and, indeed, one of these served as the back-stone of a kistvaen.

Among semi-barbarous tribes it is customary that the tribe should have its place of assembly and consultation, and this is marked round by either stones or posts set up in the ground. Among some of the great clan circles, if one of the constituent tribes fails to send its representative, the stone set up where he would sit is thrown down.

The areas within the circles on Dartmoor, so far as they have been examined, show that great fires have been lighted in them; the floors are thickly bedded in charcoal. It may be that they were the crematoria of the tribe, and certainly numerous cairns and kistvaens are to be found around them; or it may be that great fires were lighted in them when the tribe met for its parliament, or its games and war-dances. It has been noticed that usually these circles of upright stones are placed on the neck of land between two rivers.

Some have speculated that they were intended for astronomical observation, and for determining the solstices; but such fancies may be dismissed till we have evidence of their being erected and employed for such a purpose by some existing savage race.

The Samoyeds were wont to make circles of stones of rude blocks set up, and these are still to be seen in the districts they inhabit; and although these people are nominally Christians, yet they are secretly addicted to their old paganism. Mr. Jackson, in his Great Frozen Land (London, 1895), says:—

"The rings of stones which I frequently met with in Waigatz are the sites of their midnight services, and are made, of course, by the Samoyeds. They are called yon-pa-ha-pai. It is possible that within these circles the human sacrifices with which Samoyeds used to propitiate Chaddi were offered up; and, although these are things of the past now, it is only a few years ago that a Samoyed, living in Novaia Zemlia, sacrificed a young girl" (p. 89).

A tradition or fancy relative to more than one of these circles is that the stones represent maidens who insisted on dancing on a Sunday, and were, for their profanity, turned into stone when the church bells rang for divine service. It is further said that on May Day or Midsummer Day they dance in a ring.

There are several of these circles on the moor. The finest are those of Scaur Hill, near Chagford, of the Grey Wethers—two side by side, but most of the stones of one are fallen—the circle on Langstone Moor above Peter Tavy, Trowlesworthy, Sherberton, and Fernworthy. The diameters vary from thirty-six feet to three hundred and sixty. One that must have been very fine was near Huccaby, but most of the stones constituting it have been removed for the construction of a wall hard by.

The number of stones employed varies according to the area inclosed.
