WHAT IT HAS DONE (1880-1906). 7 The scientific books in the library will be supplemented largely by the special set of monographs, student treatises, and handbooks, pur- chased from "The Museum Fund"; but these cannot be removed from the building. Photographic and Pictorial Survey of Essex.—This is the most recent result of the Club's activities, having been inaugurated as lately as the 8th July 1905, at a meeting held, by invitation of the Countess of Warwick, at Easton Lodge. Nothing further need be said of it here, as full particulars will be found on page 15. General Scientific Results.—The most tangible and enduring evidences of the scientific work carried on steadily by the Club during the past quarter of a century (other than its establishment of a Library and two Local Museums, as noticed already) are to be found in its various publications. The pages of the many volumes already issued are occupied by hundreds of papers, reports, and notes, upon geology, natural history, and pre-historic archaeology. Nearly all are essentially local in character (that is to say, they relate almost wholly to the County of Essex) and are the result of original observation and research. The number of them is so great that no enumeration of them can be attempted here; but the reader may be referred to an excellent summary of the more important of them which appears in Prof. Meldola's Address already noticed.* It may be said of them, how- ever, that, from the scientific point of view, their collective value is such that no local scientific society of the kind would have any cause to feel ashamed of and that none of equally-modest member- ship, age, and means has ever exceeded the scientific output of the Club. For the greater part of the matter which has appeared in its publications, the Club has been indebted to the researches and investi- gations of its individual members. In some cases, however, the Club as a body has undertaken original investigations which have yielded interesting results. These have been carried out, for the most part, with pecuniary assistance from members and friends; for the ordinary income of the Club is barely sufficient to enable it to carry on its every-day business and routine work. In 1880 and 1882, in the very early days of the Club, it undertook exploratory work to ascertain the age and nature of the two well-known prehistoric "Camps" in Epping Forest (Ambresbury Banks and the Loughton, or "Cowper's," Camp), and very carefully- written reports on them were published. † Another investigation over which much time and money was spent was the exploration of the mysterious Deneholes at Grays Thurrock, undertaken in the years 1883 and 1887. The results were described in a very full and well-illustrated report, drawn up by Mr. T. V. Holmes. ‡ It is not too much to claim that this report embodies all that can be usefully put forward as ascertained fact and rational theory with regard to these curious pits, which have puzzled antiquaries for centuries. Past Officers.—From the outset, the Club has been able, fortunately, to secure as its officers gentlemen of high scientific stand- ing, and the services they have rendered to it demand notice here. * The Coming of Age of the Essex Field Club, pp. 3-29. † See Transactions, vol. ii, pp. 55-68, and vol. in, pp. 212-230. ‡ See Essex Naturalist, vol. i, pp. 225-276 also Meldola's Coming cf Age of the Essex Field Club, pp. 22-24.
