116 BEPORT— 1880. 



that ia all the localities there were many more than wei'e visible, as they 

 were frequently met with completely buried in the soil, and about a foot 

 below its surface. He added that he had never seen a specimen in the 

 wood or copse immediately on the west, or, indeed, anywhere on that 

 side of the small stream which divided it from the orchard and the waste- 

 land. 



In an orchard on the New-well, or Newell, or Newill estate, about '5 

 mile towards the S.E., they proved to be as abundant as at Cleve, and our 

 guide, Mr. Jackson, stated that they were formerly quite as plentiful in an 

 adjoining field on the Farleigh estate, but that the ground had been com- 

 pletely cleared. In a copse on the Farleigh grounds, and on the edge of a 

 small stream, we saw a block in the form of a rectangular parallelepiped, 

 measuring 8'5 x 5 X 2'5 feet, thus containing upwards of 100 cubic feet, 

 and weighing not less than 7'5 tons. 



On Hannamoors, in the parish of Morleigh, blocks were very abundant, 

 and many of them of considerable size. 



Prom Cleve we had been continuously ascending, but not at a high 

 gradient anywhere. At the highest, that is, the southernmost, point of 

 Hannamoors there is a quarry in which, interbedded conformably with the 

 ordinary soft slaty Devonian rocks of the district, there is a bed of 

 quartzite, identical in character with the travelled blocks we had been 

 studying, and of which it is no doubt the parent. This quarry is adjacent 

 to the high road passing westward through the villages of Halwell and 

 Morleigh to the town of Modbury, and occupyiiig the crest of the hill on 

 the northern slope of which all the blocks we had seen during the day 

 Avere lying. We crossed this road a few yards west of the turnpike gate, 

 about half a mile west of the village of Morleigh,' and almost immediately 

 entered a quarry on the southern slope of the hill, where we found another 

 exposure of the quartzite bed. Indeed, both quarries are worked to obtain 

 the quartzite for the roads. The bed dips about 30° towards (true) S.E. 

 nearly. So far as has been observed, the travelled blocks of quartzite 

 existed only on the southern slope of the hill ; they formed two parallel 

 trains extending northwards, from near the ridge of the hill, along the 

 distinct secondary valleys of Newell and Cleve ; there are none on the 

 minor north and south ridge, which divides the said valleys ; the Cleve, 

 that is, the western, train is the longer and reached the lower level ; and, 

 measuring as the crow flies, is about '5 mile long. 



There can be no doubt that the blocks had been transported from south 

 to north, and from higher to lower ground. The gradient, however, is 

 very slight, and, as almost all the blocks are very angular as well as large, 

 it is difiicult to suppose that their transportation was the result of nothing 

 more than running water. 



Should blocks be also found on the southern slope of the hill, they 

 would not necessitate any further modification of the foregoing conclusions 

 than the substitution of the words ' both northwards and southwards ' for 

 the words ' from south to north.' 



None of the blocks we saw bore any scratches or traces of polish.
