The site here to be described was discovered in November 1940, when the writer was examining mechanical excavations near Longdown Lane, Epsom, for archaeological material; and it consists of a shallow pit containing remains attributable to the Iron Age. The site (fig. 1) lies about 330 ft. above O.D. on a northward sloping spur of the North Downs. Thus the subsoil is Upper Chalk (Marsupites Zone); but in places this is capped with Tertiary clay, and occasionally there are deep flaws in the rock, also filled with clay. The modern plough-soil hereabouts is 1 ft. thick, and below it is a layer of old plough-soil visible as brown clay with small chalk particles, on an average 6 in. deep. In the edge of the mechanical excavation above mentioned there was seen (fig. 2) a pit sunk through the brown plough-soil into the natural clay pocket, and its top had of course been removed by modern ploughing. The pit was filled with dark soil; its floor was flat and lay 2 ft. from the surface and was 2 ft. 2 in. wide. The dark filling contained small potsherds, tiny particles of charcoal, bone burnt and unburnt, and the lower stone of a saddlequern.
The writer salvaged as much as was practicable on the spot, and later obtained permission to empty the whole pit; but it was not possible to clear any large area and search for post-holes. When cleared, the pit was seen to have a level floor and to be roughly circular with a diameter of 3 ft. The walls were not undercut, but sloped steeply down to the flat floor (fig. 2).
