On Dartmoor, in Devonshire, many circles yet remain, as they do also in Cornwall and in other counties. Mr. Blight, who has paid a vast deal of attention to the antiquities of his native county, Cornwall, has collected together many data concerning these structures, which tend to throw much light upon their modes of construction, as well as uses. To his researches I am indebted for much of the following information regarding the Cornish circles, and also for the diagrams which illustrate it. Upright stones were, as in the case of the ring fences already named, placed at tolerably regular intervals around the barrow, either on the natural surface of the ground or on a circular embankment thrown up for the purpose. The intervening spaces were then, in many instances, filled in with small stones, so as to form a compact kind of wall, as shown in the next engraving. This mode of construction was adopted for encircling grave-mounds, and in the forming of hut dwellings, etc. It will easily be seen that in course of time the loose walled parts would be thrown down and disappear, while the uprights, being firmly fixed in the ground, would remain, and would thus form the stone circles as now seen, and as commonly called “Druidical circles.” In some instances, as in the case of the circle enclosing a perfect stone cist, covered by a mound, at Sancreed, shown on [fig. 71], the upright stones touched each other, and thus formed a remarkably fine enclosure. This circle is about fifteen feet in diameter. Another variety is shown in [fig. 72]. This is a double circle, or rather two circles, one within the other, and about two feet apart, surrounding a stone cist. The stones in this example nearly touch each other. A somewhat similar one, but with the circles farther apart from each other, exists in the Isle of Man, and is shown on the ground plan ([fig. 73]). The mound in this instance, probably, rose from the inner circle only, and covered the central cist. In several instances the interment was not in the centre of the circle, but was made in different situations within its area. For instance, in the next example ([fig. 74]), from Trewavas Head, the cist is near to the circle of stones. The outer diameter of the mound is thirty-five feet, the diameter of the circle of stones being nineteen feet six inches. Other examples, similar in arrangement, might be adduced. [Fig. 75] shows a totally different construction. In this instance the circle is composed of a number of stone cists, or sepulchral chambers, pretty close together, end to end. This curious example, of which a somewhat analogous one exists in the Channel Islands (see [fig. 76]), is on Mule Hill, in the Isle of Man. [Fig. 77] shows the remains of a stone circle surrounding the larger of a pair of “twin-barrows,” of which some of the stones have now disappeared. The circle is about seventy feet in diameter, and the stones vary from six to eight feet in height. [Fig. 78] is the plan of another “twin-barrow,” so called, the circle in the larger being about thirty-five, and the smaller twenty-four, feet in diameter. In the centre, at A B, are the remains of a stone cist, or chamber. “The mounds were both cairns of loose stones. Remains of other barrows, similarly formed, occur in the vicinity. There were two within a few hundred yards of the ‘twin-barrow’ last described, the greater portions of which have recently been taken away to build a neighbouring hedge, but of which I found enough to show how they were built. First, there was an enclosing circle of stones, some placed upright, some longitudinally ([fig. 79]), the intention being simply to make an enclosing fence; within this the grave was constructed; then small stones heaped over the whole, the cairn extending, by about six feet, outside the built circle.” The more perfect of the “twin-barrows” also had the cairn extending beyond the circle.
