Agri cola's work was therefore prepared about three hundred 
and forty years since. 
In the previous paper 7 a description was given of the ruined 
blowing-house situated close to Week Ford. This ruin was so 
choked with debris and overgrown with vegetation that a 
close investigation was impossible. Having obtained from Mr. 
Barrington, 8 the Duchy representative on Dartmoor, the requisite 
permission, the writer determined to remove the debris with the 
view of making a careful examination of the interior. Great 
care was taken that nothing but loose stones were moved, and 
that the structural portion remained intact. The entrance was 
first cleared, laying bare the footstone and a grooved stone which 
partly carried one of the jambs of the door. Inside, another 
grooved stone forming a further instalment for the same purpose 
was found. In addition to this, five irregularly shaped stones, 
the whole of them more or less broken, and with none of the 
circular or oval shaped cavities perfect, were unearthed. One 
had five such cavities, another four, another two, and a smaller 
fragment one. The fifth was found close up toward the south 
end of the ruin, as if it had been thrown in from the higher 
ground, which here slopes up toward the south. This stone 
had three circular cavities on each side, similar to but larger 
than that which was found in a hedge at Riddipit. Close 
to the north-west angle lay a large stone having the rounded 
appearance of a river boulder. It was nearly three and a half 
feet long, two wide and two deep. On turning it over a perfectly 
smooth flat face was disclosed, having on its surface three slightly 
oval shaped cavities, two of which were quite perfect. The 
diameters of these cavities were respectively ten and a half 
inches by eight and a half, ten inches by eight, and nine inches 
by eight. These cavities were polished smooth, a result evidently 
obtained by attrition. This smoothness is characteristic of all 
the circular and oval shaped cavities, but this specimen having 
been so perfectly protected from weathering, possesses it in the 
greatest degree. 
Close by this stone lay a portion of a rectangular mould, and

8 Since this I have received from Mr. French, of Dean Prior, a complaint 
that I should have consulted him as copyholder of the property. I acted in 
ignorance of this possession, and regret it.
