So far as can be judged from the usually worn down and mutilated condition of these Derbyshire barrows, the prevailing original form was that of a shallow dome or inverted bowl, but various transitions ending with the disc-shaped types of Dr. Thurnam occur. Their outlines are circular, unless rendered irregular by the addition of secondary mounds or the depredations of a still later age. Their usual diameters range between 30 and 60 feet, and the heights rarely exceed 6 feet; but these dimensions are occasionally less or greater. With few exceptions, the mounds are of stone, or of stone with an admixture of earth; but whether the latter is an original ingredient is often uncertain—it may be merely blown earth and vegetable mould. Broadly speaking, therefore, these Bronze Age barrows are cairns. In most instances they consist of such stones as may be gathered from the surface, simply thrown together. A slight advance upon this is the introduction of a kerb of larger stones to define the margin of the mound (fig. 6). In a further advance, the kerb is formed of one or more rings of large, flat stones set on edge in the ground and inclining inwards. In a still further advance, the whole mound may be built up of concentric rings of such inclined stones. The barrow on Grinlow[9] (on which the tower known as “Solomon’s Temple” stands), near Buxton, showed this construction (fig. 7). In the kerbed barrows, the partial removal of the looser materials of the central portion may result in a table-like mound, the kerb forming a well-marked shoulder; and if the destructive process has gone further, this may stand out verge-like—results which have been mistaken for original designs. Examples of all these are to be met with in Derbyshire. [9] _Proceedings_, Society of Antiquaries, 1895. These barrows, again, are sometimes surrounded with a bank or a ring of stones, or a combination of the two. That known as Hob Hurst’s House, on Baslow Moor,[10] is closely invested with an annular bank, and the writer has seen a similar example on Eyam Moor. In others, the bank is further away, and is usually capped or lined with a row of standing stones, a few feet or yards apart. There was formerly a good example of this variety on Abney Moor, and others on Eyam Moor with rings apparently of stones only. As the ring expanded, the enclosed mound seems to have been smaller, and consequently more easily removed by the accidents of time; and this probably explains the origin of the smaller so-called “Druidical” circles.[11] [10] _Ten Years’ Diggings_, 87.
