There is a large one in the Teign, above Fingle Bridge, that can also be made to roll with the application of a little strength.

The Rugglestone, near Widdecombe-in-the-Moor, measures 22 feet by 14 feet in one part, and 19 feet by 17 feet in another, and is 5 feet 6 inches in mean thickness. Its computed weight is 110 tons, whereas the celebrated logan in Cornwall weighs 90 tons. This stone is poised upon two points.

Roos Tor, which the Ordnance surveyors playfully render Rolls Tor, possessed two logan stones, but quarrymen have destroyed one, together with the fine mass of rock on which it stood. Near it lay a huge menhir, never removed till these depredators broke it up. I give an illustration of the head of the tor with its two logans, taken in 1852; one alone remains. On Black Tor, near the road from Princetown to Plymouth, is a small logan, with a rock basin on the top, and with a projection like a handle. It can be made to oscillate without difficulty. A small logan is near the stone rows on Challacombe in the miners' workings. Its existence is purely accidental. Another is near a collection of hut circles on the slope of Combeshead Tor.

The rock basins are numerous; they are hollow pans formed on the surface of granite slabs by the action of wind and water, assisted by particles of grit set in rotation by the wind. "That this rude and primitive species of basin formed part of the apparatus of Druidism there can be little doubt," says Mr. Rowe, "but the specific purpose for which they were designed is not clear."
