XV. enormous number of fragments of pottery, bricks, and vessels, although not one of these seems by any chance to be entire, and very few are sufficiently per- fect to indicate the capacity, or even the shape, of the vessel or article to which the formerly belonged. An old man who has lived all his life in the neigh- bourhood, and has, for many years, been in the habit of carting away earth from a mound, or "Red Hill," as he called it, says that he had moved many hundreds of loads, but has never found a single piece of whole pottery or a coin. He sometimes sees flints, but has not sufficient knowledge to distinguish between a worked or chipped flint and another ; nor can he be taught to see the difference, even with the strong inducement offered him of unlimited beer and five shillings apiece for all he found. Mixed with the earth in this and all the other mounds are large quantities of charcoal and wood- ashes, though occurring very irregularly, but there is no trace of coal. Clinkers in some places are not only common, but almost abundant, and show that great heat must have been thrown out by the fires that burnt out. In only one instance has a natural cross-section of any mound been seen or heard of, and the position of this happens to be readily accessible. It is quite close to the high road from Colchester to Mersea, there consisting of a raised causeway, called the Strood, crossing the creek mentioned above as connecting the Colne and Blackwater. This mound is about five feet thick, and is intersected by a small creek, much haunted by crabs. Of the little pottery it yielded, two pieces were Roman turned-ware, the only occurrence of such pottery yet found in the mounds. There was also much cellular semi-vitrified earth and burnt clay, with impressions of the sea-grass, Enteromorpha com- pressa. This mound has also its upper surface left in a series of narrow stetches, giving evidence of cultiva- tion during Saxon times, when that form of tillage was usually followed. Mr. H. Laver, F.L.S., of Colchester, says that another mound, at Tollesbury, was also tilled during this period, and, having been apparently abandoned to the sea, it remains outside the sea-wall, still retain- ing the characteristic narrow stetches. The total number of these mounds in Britain, or even in Essex, must be considerable, when, after centuries of destruction, eighteen still remain between Virley and the Strood, a distance of only six miles. Others are said to exist on the Crouch in Essex, in Kent, along the wide rivers of Suffolk, on the Norfolk coast, in Lincolnshire, Yorkshire, and Durham. Still they seem to occur in the greatest number and of the largest size in Essex, which is a
