 few years ago, and now may be seen at Mr. Waterer's American Nursery at Bagshot. A Roman stone near Silchester may be seen, and another near Finchampstead, that are presumed to have marked the measurement of stadia.

The black line on the side of the Roman road as mapped, denotes the situations where the aggeres or mounds may be found of the original site.

With respect to the geology of the Roman road, it may be remarked that Silchester is situated on the "plastic-clay formation;" the stone debris on the surface of which has been picked up about the inclosure, for not a flint-stone can be found for some distance around. The walls of the old city are built with flint, grouted with lime and sand, and bonded in a herringbone manner, with an oolite stone at every three feet in height. The road passes across Strathfieldsaye Park, over the "London clay formation," and there soon reaches the extensive range of the "Bagshot sands," occupied principally by native heath (erica), much of which is in the same wild nature as when the Romans were here 1,600 years ago. On this formation the road continues its undulatory and elevated direct course for many miles, bending only at "Duke's Hill," near Bagshot, until the vale of the Thames is reached, when a small part of the "London clay formation" is again passed near Egham.

Roman coins, pottery, and fragments of Roman tiles, have been discovered in various parts of this line, and are in the hands of Mr. Barton, tenant of Silchester Inclosure; a good collection of gold, silver, and copper coin, may be seen, with also spear-heads, bucklers, and horse-gear, picked up at various periods.
