The process in this country, so far as I can make out, was different, though tending to a similar result. The stone circles in Europe appear to have been introduced in supercession to the circular earthen mounds which surround the early tumuli of our Downs. These earthen enclosures still continued to be used, surrounding stone monuments of the latest ages, but, if I mistake not, they first gave rise to the form itself. Such a circle, for instance, as that called the Nine Ladies on Stanton Moor, I take to be a transitional example. The circular mound, which is 38 feet in diameter, enclosed a sepulchral tumulus, as was, no doubt, the case from time immemorial, but, in this instance, was further adorned and dignified by the circle of stones erected upon it. A century or so afterwards, when stone had become more recognized as a building material, the circular mound may have been disused, and then the stone circle would alone remain. [Illustration: 10. Nine Ladies, Stanton Moor. From a drawing by L. Jewitt.] These stone circles are found enclosing tumuli, as in the Dolmen de Bousquet (woodcut No. 8), in three rows, and sometimes five or seven rows are found. They frequently also enclose dolmens, either standing on the level plain or on tumuli, but often, especially in this country, they are found enclosing nothing that can be seen above ground. This has led to the assumption that they are "Things," comitia--or places of assembly--or, still more commonly, that they are temples, though, now that the Druidical theory is nearly abandoned, no one has been able to suggest to what religion they are, or were, dedicated. The spade, however, is gradually dispelling all these theories. Out of say 200 stone circles which are found in these islands, at least one-half, on being dug out, have yielded sepulchral deposits. One-quarter are still untouched by the excavator, and the remainder which have not yielded up their secret are mostly the larger circles. Their evidence, however, is at best only negative, for, till we know exactly where to dig, it would require that the whole area should be trenched over before we can feel sure we had not missed the sepulchral deposit. When, as at Avebury, the circle encloses an area of 28 acres,[65] and the greater part of it is occupied by a village, no blind digging is likely to lead to any result, or can be accepted as evidence.
