59 GEOLOGICAL NOTES ON A SUPPOSED EARTH- WORK NEAR THE RAILWAY STATION AT HARLOW, ESSEX. By T. V. HOLMES, F.G.S., Vice-President. WITH A REPLY BY I. CHALKLEY GOULD AND FURTHER OBSERVATIONS BY T. V. HOLMES. [The following paper was read by Mr. Holmes at the meeting on the River Lea on June 29th, 1895. As Mr. Holmes traverses the conclusions arrived at in the original paper in the "Transactions of the Essex Archaeological Society," we deem it only just to allow our valued member, Mr. Gould, to reply at the same time, and we have also appended some further observations by Mr. Holmes, written after perusal of Mr. Gould's reply.] AT the beginning of this month (June, 1895), my friend, Mr. T. Hay Wilson, asked me to go with him to Harlow to see some new sections in Glacial Drift in that neighbourhood. I did so, and as we left Harlow Railway Station, he pointed out the supposed earthwork, and was also good enough to lend me a short paper thereon, by Mr. I. C. Gould, which had been read before the Essex Archaeological Society on May 17th, 1894, and since published in "Trans. Essex Archaeological Society," vol. v. (n.s.), pp. 95-98, with plate. Mr. Gould, in concluding his paper, remarks: "Having thus touched upon the various possible dates of the construction of this earthwork, the question arises, to what are we to attribute it ? I suggest that we have here a natural oblong hill turned into a fort, which was in its origin British." And he then discusses in what ways the "fort" or "earthwork" may have been modified by races occupying the district at later periods. Mr. Gould notes that an account of the discovery of Roman remains at Harlow, together with a brief notice of this earthwork, may be seen in the "Archaeologia" for 1821, p. 409; also in the "Gentleman's Magazine" for the same year, part i., p. 66. In the "Gentleman's Magazine Library," no mention is made of anything at Harlow in the two volumes devoted to "Archaeology," or in those treating of Romano-British antiquities. And in "English Topo- graphy," part iv., though there is a notice headed "Harlow," in the portion assigned to Essex (p. 118), there is no mention of this earthwork, though there is some account of the discovery, in 1841,
