The mounds of earth alluded to, present occasionally highly interesting and curious features, and show that, like those of a different construction, they have frequently been used for successive interments. The section of one of these is shown on the next page. It is one of a group of six barrows on Lord’s Down, in the parish of Dewlish, in Dorsetshire. It was eighty-two feet in diameter, and fourteen feet in height in the centre. The primary interment, an urn, was placed in a cist cut in the chalk sub-soil. Over the urn was raised a small cairn of flints, and the cist was then filled in, and raised a little above the surface with chalk rubble. Over this was a layer of earth, upon which an interment had taken place, and in its turn covered with a thick layer of chalk rubble, in the centre of which, in a cist, another interment had again been made. Above this rose another layer of earth, another of chalk, and then a final one of earth, on each of which interments had at different periods been made. Thus the tumulus, which was formed of alternate layers of chalk and earth, exhibited no less than six successive sepulchral deposits.[2] The interments were both by inhumation and cremation. [Illustration: Fig. 2. 1. Earth to the depth of three feet. 2. Chalk, two feet in depth. 3. Earth to the depth of three feet. 4. Loose rubble chalk, three feet in depth. 5. Earth, one foot in depth. 6. Chalk rubble, six inches in depth. Cist, filled with chalk rubble and flints, two feet in depth. ] Another example of a barrow of this period is shown in section on the fig. 3. There had originally been four small mounds, or barrows, formed in a group, on the natural surface of the ground (see the two dotted lines in the engraving). They were composed of tempered earth, approaching in tenacity almost to clay, and on these the general mound was raised to a height of about eighteen feet, and was composed of earth, intermixed with loose rubbly limestones. Nearly at the top, in the centre, a stone cist, enclosing an interment, was discovered. It was in form a perfect, though miniature, example of what are commonly called cromlechs. [Illustration: Fig. 3.] It is not an unfrequent occurrence in barrows to find that interments have been made at different periods and by different races, as will be hereafter shown. The two examples of mounds of earth already given will show the successive layers which have occurred in their formation. The simpler, and intact, mounds of earth, which are very common, require no illustration. They are simply immense circular heaps of earth raised over the interment, whether in cist or not.
