In the Appendix to the Preface of the first volume of the 'Sculptured Stones,' Mr. Stuart records excavations made in some fourteen circles, similar, or nearly so, to this one at Rayne; and in all sepulchral deposits, more or less distinct, were found. In some, as in that of Crichie, before alluded to, a sepulchral deposit was found at the foot of each of the six stones which surrounded it. Like many of our English circles, this last was surrounded by a moat, in this instance 20 feet wide and 6 feet deep, crossed by two entrances, as is Arbor Low and the Penrith circle, and within the moat stood the stones. As a general rule, it may be asserted that all the Scotch circles, having a diameter not exceeding 100 feet, when scientifically explored, have yielded evidences of sepulchral uses. Such, certainly, is the result of Mr. Stuart's experience, as detailed above; of Dr. Bryce's, in Arran; of Mr. Dyce Nicol[304] and others, in Kincardine; and elsewhere. Colonel Forbes Leslie informs me that he has not been so fortunate in some of those he mentioned in his lecture, which he either opened himself or learnt the details of on the spot. Some of these he admits, however, had been opened before, others disturbed by cultivation; and altogether his experiences seem to be exceptional, and far from conclusive. The preponderance of evidence is so overwhelming on the one side, that we may be perfectly content to wait the explanation of such exceptional cases as these. The Aberdeenshire circles are all found scattered singly, or at most in pairs, in remote and generally in barren parts of the country; so that it is evident they neither marked battle-fields nor even cemeteries, but can only be regarded as the graves of chiefs, or sometimes, it may be, family sepulchres. There is one group, however, at Clava, about five miles east from Inverness, which is of more than usual interest, but regarding which the published accounts are neither so full nor so satisfactory as could be wished.[305]
