68 FURTHER REMARKS BY T. V. HOLMES. in which, if I remember rightly, no water appears to spring within the works, but in each case a brook is at the foot ot the slope. But in the case of the Harlow hill, there is evidence not only of a supply of water from outside, but of a pond or reservoir on the earthwork itself! Just below the lower court or terrace are the remains of a pond, provided with a ditch to carry the surplus water to the deep dyke on the N. of the works. I do not claim to be a geologist, and hesitate to raise a ques- tion in that field against so redoubtable a champion ; but, as a mere layman, I would ask if, as Mr. Holmes says, the hill is all London Clay, whence comes the water to this pond, which is some feet above the alluvial ground of he marsh ? FURTHER REMARKS ON THE ABOVE PAPERS. By T. V. HOLMES. Since the foregoing notes were read at the meeting of the Essex Field Club, on the River Lea, June 29th, I have been favoured with a sight of Mr. Gould's reply to them. It seems best to notice here, as briefly as possible, the points brought forward by Mr. Gould. He remarks, in the first place, that my explanation of the way in which this Harlow hill was shaped, by a change of course of the Stort, has no bearing upon the archaeological question. But as Mr. Gould has no explanation of any kind to offer on this fundamental point, and as the writers in the "Gentleman's Magazine," and "Archaeologia," quoted by him, were evidently ignorant of the explanation given, it became necessary to bring it forward. It would have been absurd to consider other questions without settling that one first. The discovery of Roman coins on the hill would show nothing as to its occupation.3 Coins may be found anywhere. They were buried in thousands of places by thousands of people, from the earliest periods up to the present day, and are as likely to be found near an old tree as an old house. Besides, the question is whether this Harlow hill is an ancient earthwork or castellum, on which coins can tell us nothing. Then, as to the ditches at the base of the hill, Mr. Gould seems to think that because one of these ditches keeps for some distance 3 I do not gather, however, from "Archaeologia," and the "Gent. Mag." that any have been found on the hill itself.
