EXPLORATION OF SOME "RED-HILLS" IN ESSEX. 183 " One of the two pieces from Peldon appears to belong to the class of ware known as late-Celtic.8 "As there was an overlapping of the late-Celtic and Roman period, and the forms of the fictile vessels of both these sources of culture appear to have been made simultaneously, it is common to find the two in association. The occurrence of late-Celtic types, therefore, does not necessarily indicate an earlier period. I have already drawn attention to this elsewhere, but it is a point that cannot be too strongly insisted upon. There is no reason why some Red-hills should not have originated in pre-Roman times, but this can only be determined by extended enquiry; such a conclusion cannot be drawn from isolated specimens. The weight of evidence so far points to their origin in Romano-British times." As before stated, I simply put forward the above supposi- tions in a tentative way to suggest further enquiry, which the newly-appointed Committee of the Essex Archaeological Society and the Club will doubtless give to the matter, to confirm, extend, or possibly confute, the conclusions here set forth. There are numerous very interesting questions connected with geology, topography, and even the biology of our coast suggested by the problems of the Red-hills. The density and salinity of the estuarine waters as compared with the open sea is one of them, and the age of the alluvium and the older sea-walls, are others. It is a large and very interesting subject, and one worker can do very little, but my brothers and I have had much satisfaction in making up the above sheets, and recalling the many pleasant days spent on the breezy Essex marshes with the Red-hills and the curlews. [The Club is indebted to Mr. H. A. Cole, for the drawings accompanying this paper. It should be stated that the drawings on pp. 175 and 176 are one-half the natural size of the objects.] 8 These pieces came from Mr. Stopes, and ate presumably the fragments alluded to in his paper, E.N. I., page 99.
