EXPLORATION OF SOME "RED-HILLS" IN ESSEX, 173 These thick pieces are apparently portions of large vessels, some at least cylindrical in form, and as much as twenty inches in diameter, with the ware an inch or an inch and a-half in sub- stance.2 The larger fragments found were very soft and fragile whilst moist, and readily broke up on attempted removal from the matrix. There is an appearance on some pieces of careful smoothing of the clay on the inner side, but we saw no indications of glazing on the Burnham specimens. These coarse pot-shards constituted in some places quite one-fourth of the whole mass of rubble excavated. We often found portions of curious objects, which we termed "T-pieces"; they were largely fragmentary, but one of the most perfect found at Burnham is shown at B, Fig. 1. The "shaft" had apparently been much longer, but had been broken off. Wedge-shaped bricks of the same kind of clay also occurred not uncommonly; two are figured at C and D, Fig. 1. A small number of fragments of a harder and better kind of pottery were picked out of the mass of debris; it is of the kind commonly called Romano-British. Specimens from the Bower Hall Farm, Red Hill, East Mersea, are pictured in Fig. 3, post. They formed a very small percentage of the rude pottery fragments. Some of it is apparently wheel-turned. Two small fragments of Samian ware occurred at Burnham; we found no trace of it in any other Red-hill. At the time we considered them accidental, and fancied that they might have been carried down from the surface by the burrowing of rabbits, or by rain-wash. Our next experiences of Red-hills explored in any careful way, were during our summer vacations in Mersea. One very considerable "hill" was found on Bower Hall Farm, East Mersea. This mound is situate on the saltings bordering the Pyefleet Channel, outside the sea-wall (it is marked on the 6in. Ordnance Map, "Sheet 47, N.W, East Mersea," very near the B.M., 13-5.). The Red-hill is partly cut through by the Pyefleet, so causing a natural section, which exhibits the characteristic features of such remains excellently—the usual pottery is seen sticking out from the exposed burnt earth.
