One of the finest gravel-pits in the world for flint implements is in process of extinction, and a final opportunity has been given for studying its stratification with a view to classifying, however roughly, the thousands of specimens from this site that have passed into public and private collections both at home and abroad. Every collector is familiar with the name of Swanscombe, a village on the south bank of the Thames between Dartford and Gravesend, and many have procured implements from the workmen on the spot without realizing to the full the necessity of fixing the horizon of each, if their purchases are to be of scientific value.
Smith et al. (Wed,) studied this question.
