2 It has long been felt that, if systematic study were devoted to the Red-hills, further light would be thrown on questions of deep interest, connected not only with early industries, but also with the physical and geological changes through which this country has passed. With this in view, Mr. I. Chalkley Gould suggested to the Council of the Essex Archaeological Society, on the 19th April 1906, that the Society should appoint a Committee to invite the co-operation of the Essex Field Club (which had previously had the matter under its consideration) in setting on foot a systematic scientific examination of the whole problem. Ultimately, your Committee was constituted as a Joint-Committee of both the Societies named, and with power to add to its number. At its first meeting, it elected Mr. I. Chalkley Gould as Chairman, Dr. Henry Laver as Director of Excavations, and Mr. H. Wilmer as Hon. Secretary and Treasurer. To provide immediate funds, the Essex Archaeological Society voted £10 and the Essex Field Club an equal amount (payable in two equal portions during 1906 and 1907). The Society of Antiquaries also granted £10, and other smaller sums were subscribed. In order to facilitate the accurate mapping of the Red-hills, the Director-General of the Ordnance Surveys of England and Wales has presented ninety-one six-inch maps showing the Essex coast. It is hoped that the work your Committee is doing will enable the Ordnance Survey to indicate the sites of the Red-hills on its maps in future. In September last, your committee commenced the work of excavating in the parish of Langenhoe, Dr. Laver having secured permission to examine some characteristic Red-hills existing there. The work extended over five weeks, during the greater part of which time three men were employed. The scene of the digging was visited constantly by various members of your Committee, but the detailed personal supervision of the work was carried out from beginning to end by Mr. Francis W. Reader, whose training in the systematic examination of prehistoric sites and settlements, acquired under the late General Pitt-Rivers, Inspector of Ancient Monuments, renders his assistance of the greatest value. Of the three mounds which were examined systematically, the first proved the most interesting. It was, unlike most examples, quite complete, no portion of its soil having been removed for agricultural
