THE MOORLAND PLYM.

activity on the part of the streamers. A leat which is taken out 
of the brook on the west side is carried for some distance along 
the steep slope of the hill in made ground, and to support this a 
retaining wall of considerable height has been erected. A little 
further up, and on the eastern side of the combe, is a ruin which 
may once have been a blowing-house ; but I hazard this statement 
with caution. 
Near the head of Langcombe, on the eastern hill, is the kistvaen 
known as Grimsgrove, or Grave. The tomb is better built than 
is usual, and the cover-stone, which has now fallen in, was trimmed 
square to fit it. The measurements of the kist are 3ft. 3 in. by 
2ft. 9in., by 2ft. deep, and a circle of stones fourteen feet in 
diameter surrounds it. This circle contains nine stones, all of 
which are standing. (See figures 7 and 8.) 
Near Calveslake Tor is a mound eighteen feet in diameter, 
supporting a kistvaen 1ft. 6in. wide, by 3ft. 7in. long, and 1ft. 
7in. deep. (See figure 9.) 
The cover-stone has been removed, and rests in a slanting 
position partly overhanging the tomb. It is irregularly shaped, 
and its longest diagonal is seven feet, its shorter being six feet. 
In Evilcombe, opposite Calveslake, are the remains of a beehive 
hut, the wall of which still stands to a height of 4ft. Bin. The 
extreme inside diameter of the hut cannot be obtained, but is 
probably seven or eight feet, while at three feet from the floor the 
diameter is five feet. This is the only hut in the Plym valley in 
anything approaching a perfect condition. (See figure 10.) 
From Evilcombe to the Abbot's Way the whole ground has been 
disturbed for tin. Nature left this stretch of country in an ex- 
ceedingly rough and incomplete condition ; but subsequent efforts 
on the part of the miners in many ages have most certainly not 
improved it. As a rough bit of walking this portion of the valley 
cannot be excelled. Natural quagmires, artificial ponds of varying 
sizes and depths, rabbit burrows covered only by thin crusts of 
fragile soil, short galleries driven into the ground by tin-searchers, 
and mounds of spoil fetched forth from the galleries, all conspire 
to render broken limbs, if not premature decease, possible inci- 
dents for the adventurous traveller. 
This district has been mined within recent years ; and in the 
valley above Evilcombe are the remains of a complete crushing 
plant for tin ore.
