ANCIENT EARTHWORKS field for archaeological exploration which may set at rest the long-debated question as to their age and purpose. THE 'DENEHOLES' Hangman's Wood near Grays 1 contains the curious pits known as ' deneholes,' which have been a mystery to enquirers from the days of Camden* to the present time. Many writers have in modern days issued papers on the subject, but the gist of the information will be found in the Essex Naturalist, edited by Mr. W. Cole, who, with Mr. T. V. Holmes, has devoted much time and attention to the examination of the pits in the course of explora- tions undertaken by the Essex Field Club with a view to the elucidation of the mystery surrounding their age and purpose.* ^HP?? 4 V J i -* * ..

Holmes, F.G.S.) Seventy-two deneholes have been counted within 4 acres of Hangman's Wood mostly near together and consisting each of a ver- tical shaft carried down from 50 to 100 feet through Thanet Sand into the Chalk. The shafts are from 3 to 4 feet in diameter and end in caves or excavations branching into chambers of about 20 feet in length. The shafts have become more or less closed up by soil and debris from above, those pits which were cleared by the Essex Field Club in their explorations showing each a great heap of sand and soil at the base. 1 The wood is partly in the parish of East Thurrock and partly in Orsett. Deneholes appear also to have been found in the adjoining parish of Chadwell St. Mary.
