234 TRANSACTIONS OF THE PLYMOUTH INSTITUTION. 
In concluding the last paper, reference was made to a cache or 
hiding-place for metal or tools, situated above the ruined blowing- 
house at Deep Swincombe. As previously mentioned, there are 
two more in the stream work close to the caves in the Deancombe 
Valley, which may have been used for the same purpose or for 
temporary shelter. 
There are also small huts of a circular shape to be found in 
stream works, which are too small for habitations, but doubtless 
served the purpose of small storehouses. All that have been 
examined are covered with small mounds of earth and turf, and 
were very easily and effectually concealed. Even in their present 
condition they are not easily detected, especially if approached 
from the back, and the entrance out of view. The roofs are of 
the bee-hive pattern, and are formed of stones placed one on the 
other, with each stepping nearer the centre, until a larger stone 
placed on the top completes the arch. Mr. Spence Eate has 
described some of these huts on the Avon and Erme. That 
which is on the right bank of the latter river in a stream work 
running down from Staldon Moor is quite perfect, and is just six 
feet long, four wide, and three high. The entrance to this hut 
is defended by a dwarf wall, which served not only for conceal- 
ment, but also as a barrier, should the brook, on whose bank it is 
situated, rise in flood. There is another hut similar to this, also 
in the midst of " old men's " workings, at Ladle Bottom, about two 
and a half miles above Post Bridge on the East Dart. The roof 
is partly broken in, but sufficient remains to show that it is of 
precisely similar construction. These ancient store-huts are of 
great interest, and it is to be hoped they may long remain as 
examples of the manner in which such curious little buildings 
were erected. 
At the head of the Deancombe Valley, rising nearly 1500 feet 
above sea-level, is the hill crowned with the tumulus known as 
Eylesbarrow, or, as it is spelt in the ancient map defining the 
boundaries of the Forest of Dartmoor, Elysburgh. This has been 
for centuries a tin-bearing centre, and near it are extensive 
prehistoric remains. Not far from Eylesbarrow, but closer to 
Down Tor, are the remains of a fine avenue of upright stones 
about a thousand feet long, leading from a circle to a circular 
pound a hundred feet in diameter, with a tumulus close by the 
latter. For miles around the valleys and shallow depressions have
