appears to be round, and contains a small iron plug run in with 
lead. 
The native previously referred to said it was formerly used as 
a weight. It may have been employed for this purpose, and the 
iron plug in the central hole might be the remains of a hook, 
although the size of this hardly appears sufficient to carry so 
heavy a weight. Whatever it may have been recently used for, 
it has all the appearance of originally serving the purpose of the 
upper stone of a small mill, such as might have been used for 
hand power only. The smoothly ground base and triangular holes 
in the top for the reception of prongs which carried the cross bar 
favour this assumption. 
Eunning east of Eiddipit is a gully which has been streamed. 
It terminates about a quarter of a mile distant, at the remains of 
Keaglesburrow mine, which ceased working in 1810. Here also 
may be seen evidence of mining operations of an ancient character, 
and quite unlike the ruins of the modern mine. 
A little further east is Clazywell Pool. It is about an acre in 
extent, and has been excavated out of the slope of the hill facing 
south. When well filled with water it has a depth of from fifteen 
to twenty feet. The banks on all sides, excepting the south, are 
high and steep. Here the tin probably " bunched," and hence the 
pit. The only other pool like this on Dartmoor is that of 
Bradford, or Bradmere, near Drewsteignton, which however is 
larger and said to be much deeper. Although the latter sheet of 
water has excited the imagination of those who see the Druids' 
handiwork in all the riddles of the Moor, the popular notion that 
it was connected with tin mining is correct. 1 
From the southern side of Clazywell, a deep stream-work leads 
down to and intersects the rough moorland track which runs from 
Kingsett to Nuns Cross and Whiteworks. Across the track and 
under the northern boundary of the adjacent field is a ruin, but 
there is nothing particular about it to determine its character. 
The whole of the valley right up to Nuns Cross has been pulled 
about and disturbed in a most remarkable manner. The ruins of 
Plym Consols and Nuns Mine can be more plainly seen, but the 
more ancient remains have been buried up or obliterated. 
1 Mr. Ormerod states, in an article on "Tin Streaming near Chagford," in 
vol. i. of Devonshire Association Transactions, 1866, that the water in this 
pool has accumulated during the last seventy years.
