Neolithic implements are of stone, but in many cases they are unlike the older implements in being of polished stone. In the Reading Museum there is a fine polished flint chisel from Englefield, and also polished axes from Broadmoor, from Pangbourne, and from the beds of the Thames and Kennet. In the British Museum there is a beautiful dagger of flint from a barrow on Lambourn Down. Pretty little arrow-heads have been found at many places on the downs and in the Wallingford district. There was in Berkshire a long interval between the Palaeolithic and the Neolithic Periods, but so far as we know there was no such break between the Neolithic Period and the Bronze Age. All we can say is that there was a time when the inhabitants of our district began to use implements of copper, or of copper alloyed with tin, i.e. bronze, for some purposes, but they still continued to use implements of stone, and it is not always possible to say whether a stone implement belongs to the Neolithic Period, to the Bronze Age, or to an even later date. Many remains of the Bronze Age have been found in burial-mounds or barrows, and the barrows of this period are circular, with a diameter of fifty to one hundred feet, and hence termed round barrows. Many pieces of sepulchral pottery of this age from Berkshire will be found both in the British Museum and the Reading Museum. A considerable number of bronze implements were found in one place at Yattendon, and another hoard of them was discovered at Wallingford. A great many bronze swords, daggers, and spear-heads have been found in the river Thames, and are to be seen in the Museums. A cemetery of this period was found at Sulham, and many earthenware urns from it are in the Reading Museum. There are also in the Museum some urns from Neolithic barrows at Sunningdale. The extensive deposits of peat at and around Newbury show that it was a marsh and lake district until historical time, and remains of pile dwellings have been found in the market-place, in Bartholomew Street, and in Cheap Street. Their date cannot be fixed with certainty, but they are almost certainly prehistoric in age. The substitution of iron for bronze indicates a considerable advance in knowledge, for, except in meteorites, pure iron is not found in nature, and no small skill is required to separate the metal from the earth or rock in which it occurs. There is, however, no definite division between the Bronze and the Iron Age, for implements and ornaments of both bronze and stone continued to be used. Nor is there any definite end to the Iron Age: it passes onwards into the period of written history. A number of bones and various objects found in a grave on Hagbourne Hill seemed to show that a man, a horse, and possibly also a chariot had been buried there.
