earth, and was not evidently part of and adjoining to another, to be a distinct and separate body or stone by itself.

The form of this monument is not only described but delineated in most authors, and, indeed, it is hard to know the first but by the last.  The figure was at first circular, and there were at least four rows or circles within one another.  The main stones were placed upright, and they were joined on the top by cross-stones, laid from one to another, and fastened with vast mortises and tenons.  Length of time has so decayed them that not only most of the cross-stones which lay on the top are fallen down, but many of the upright also, notwithstanding the weight of them is so prodigious great.  How they came thither, or from whence (no stones of that kind being now to be found in that part of England near it) is still the mystery, for they are of such immense bulk that no engines or carriages which we have in use in this age could stir them.
