134 UNEXPLORED FIELDS OF ESSEX ARCHAEOLOGY. as it would seem, disadvantageous conditions. This being so I suggest that the alluvium of all the Essex rivers above the tidal points is a likely field for Neolithic exploration. Excava- tions in that deposit are rare, and observations, I am afraid, have been still rarer. Of the two or three excavations that I have known relics have occurred in every case, but they were scarcely noted and certainly not preserved. With such a breadth of unexplored territory as is here presented it is easy for speculation to run somewhat rife. It is therefore the more incumbent on me that I confine myself to what I submit may be justifiably inferred. If we consider these lakes or ponds to represent places of habitations, as we are justified in doing by the quantity of relics that continually recur, then we may assimilate them to the lake dwellings of the river valley, the existence of one at least of which is placed beyond doubt. We have thus a whole county presented to our eyes inhabited by an amphibious population. Had these been in the heyday of their prosperity when the Romans invaded the land we should certainly have had some record of them, but as no record is forthcoming, we presume that that population had gone entirely. Perhaps the next relic in chronological order, if, indeed, it is not contemporary, and of which but little notice appears to have been taken, is the ancient system of roads that occur in Essex. There is one system that can very well be made out that must be of great antiquity. It is those roads that skirt the rivers from their sources to the sea. These roads often go along the edge of the Alluvium and give rise to the unmistakable inference that they at one time represented the hard path by the water's edge. It is not easy to assign any of them to a date on this side of the Roman occupation. They were certainly not made by the Romans, as there is good evidence to show. In connection with these roads are other minor roads, of which no system can be made out. They led sometimes to, and can be shown to have been in connection with, the lakes or ponds of the interior. If then we suppose the main system to have been in use by the river dwellers, then these minor roads would stand as secondaries to that system. It is chiefly because of their connection with the ponds and river system, and their total independence of the Roman roads, that I thought they may be of such great antiquity.
