large solitary pointed stone, five feet high, the only one left of 
what must have been a magnificent circle, about eighty feet in 
diameter. See sketch No. 6. 
Double circles, with ruined cromleacs, are seen west of this 
in the same field. 
Near the pond, at the bottom of the hollow, there is what 
appears to be a cist of unusual construction. There is a very 
large flag-like stone, flush with the surface, under which is a 
hollow space. I pushed my umbrella into it, through an opening 
on one side, and could swing it about. It was too dark inside 
to see anything. The peculiar feature is this:— On the top of 
the flag, and placed round it, resting partly on the flag and partly 
on the surrounding soil, are a number of large stones, as if put 
there to keep the flag down and prevent its being raised. What 
can this be ? I have never seen any similar structure. 
Just over the wall, in the field at the top of the hill, is seen 
a very remarkable cashel or fort. It may be called roughly 
square, the sides being about one hundred and twenty feet long. 
The circumscribing walls are perhaps ten feet thick, and are 
made up of earth and massive stones. There are two entrances 
on opposite sides, north and south. The interior is divided by 
cross walls at right angles, and there appears to have been a 
cist or structure of some sort in it. There are a ditch and bank 
outside the wall. Altogether, it is very difficult to say what 
this really was, its appearance being so very different to what 
is usually found in forts, &c., and excavation would be necessary 
to settle the question whether this was a place of sepulture or 
not. Can it have been the great Firbolg stronghold ? Dr. 
Petrie numbers it 46. 
Leaving the cashel and passing to the east, in the direction 
of Cloverhill, keeping near the wall, we soon come upon the 
last of the perfect cromleacs left on Carrowmore. It is Dr. 
Petrie s No. 37. It stands in the centre of a triple series of 
circles still there. The cromleac is small, the cap stone being 
about sixteen feet in circumference, and resting on five stones.
