18 PKOCEEDINGS OF THE GEOLOGICAL SOCIETY. [Mar. 24, 



and two on the southerly boss ; and of these the particulars are given 

 in the Table. One large basin on the central platform will require 

 description. This basin was discovered by the Author on 17th Sept., 

 1856. The opening at the top, as marked by the line to which water 

 stands when it is full, is oval, measuring 8 feet from N. to S. and 

 6 feet 8 inches from E. to W. A few inches below this level the basin 

 is nearly circular ; the diameter half way down is 50 inches ; at the 

 bottom 24 inches : the perpendicular depth is 31 inches. The bottom 

 is flat, rounding up at the edges to the sides, which curve outwards 

 in the form of the mouth of a trumpet, and two indentations, caused 

 by decay, run round the basin. The bottom and sides up to the 

 lowest indentation (12 inches) were covered with dead Sphagnum, 

 which formed a compact mass, adhering so closely as to have taken 

 a cast of the granite ; between these there were not any stones, nor 

 the small fragments of quartz and felspar usually found in rock- 

 basins. At the bottom of the basin, above the Sphagnum, there was 

 a thin layer of fine black peaty soil, and the remaining contents — 

 evidently of a later date — consisted of, first, a compact mass of fine 

 dark sand and gravel 6 inches in thickness, and above this a brown 

 peaty soil containing fragments of quartz and felspar, which filled 

 the basin to the level, and the whole was covered over by a thick 

 growth of heath. This arrangement is such as would arise from a 

 maceration of peat exposed to the wet and storms that occur at this 

 spot. Attention having been attracted by the opening of this basin, 

 the Author has received information derived from an old " Moorman," 

 which leads him to suppose that the basin was filled with peat be- 

 tween 100 and 150 years ago to prevent accidents to sheep. This 

 basin has not been empty of water since it was opened in Septem- 

 ber, 1856. A short distance below the junction of the North and 

 South Teign Rivers, at Legh Bridge, on a spur projecting on the 

 right hand of the valley, a rock-basin is found on the top of a large 

 transported block of granite known as the Puckie stone. This basin is 

 irregular in shape, and measures 40 inches from N. to S. and 43 

 inches from E. to W. The longest diameter is nearly N.W. to S.E., 

 58 inches ; the sides are nearly upright, and from 2 to 5 inches 

 high ; the bottom is nearly flat, but rough from the projecting fel- 

 spar ; it was covered with fine sand composed of disintegrated granite. 

 The rock is broken through the centre, and the fracture must have 

 taken place since it was placed in its present position. The Eiver 

 Teign runs in a hoUow about 80 feet below this stone ; and it seems 

 very probable that the spur on which this stone is deposited, formed 

 part of the lower bank of a small lake extending upwards to the 

 commencement of a narrow gorge above Gidley Park. On Middle - 

 ton (or Meldon) hill, above Chagford, there are several basins. In 

 Pushford woods, near that town, to the north of the Teign, there is 

 a basin called " The Punch Bowl," on an insulated piece of rising 

 ground known as " The Bowling Green," and a small irregular basin 

 is formed on the Tors at Sandsgate near the same locality. At Wil- 

 listone, as before mentioned, there is a perforation in the side of a 

 basin. Near Bridford, at Hell Tor, we find several basins. A cleft
