A combination of circumstances having recently brought the Canterbury gravels into prominence, a preliminary survey of some implement-bearing deposits in the Stour valley is now offered to the Society for comparison or contrast with the report on the Swanscombe and Dartford areas in the Thames valley published in Archaeologia, lxiv and lxv. The map of Kent issued by the Geological Survey in 1865 showed only the solid geology, not the Drift deposits, which date from the human period and provide abundant (if often puzzling) evidence as to the sequence of primitive dwellers in this region. The geological map is now being revised, four sheets having already been published; and as the series of memoirs accompanying the sheets includes a survey of the palaeolithic relics and conditions, a special effort is required to disentangle the recent geology of the Stour valley, which, in comparison with the lower Thames, has been unaccountably neglected.
