160 A SKETCH OF THE GEOLOGY OF EPPING FOREST. Committee, through whose courtesy succeeding issues will also, I understand, be forwarded as they appear. By way of pendant to this meagre outline I must express the gratification I have had in arranging and cataloguing these papers, which, had it not been for the enlightened foresight of Mr. Johnston and of Mr. Barclay's executors, might easily have followed so many other valuable records to the funeral pyre. It is to be hoped that other residents in the neighbourhood of the Forest, stimulated by their example, may send documents of a like nature to the Library, there to be preserved for the use and instruction of those who, in the long years to come, may wander in an even nobler forest than that which we ourselves are privileged to behold. [We may add that the Librarian and Curator will be very glad to receive copies of any books, pamphlets, reports, maps, etc., relating to, or containing matter relating to, the old Waltham Forest, its Topography, Antiquities, History, and Natural History, and of the various "fights for the free forest" from the earliest periods until now. It is particularly desired to obtain copies of the Minutes of Evidence of the Epping Forest Commission ; the Minutes of Evidence at the trial of the action before the Master of the Rolls in 1874 ; and of early maps of the Forest district, particularly Chapman and Andre's fine map of Essex, etc. Any contributions, addressed as above, will be gratefully received at the Museum at Queen Elizabeth's Lodge, and donors will have the gratification of aiding in the gathering together of a perfect set of Forest literature, which at present nowhere exists, although the Field Club's Library is the most complete, probably, of any collection of such material.—Ed.] A SKETCH OF THE GEOLOGY OF EPPING FOREST. By T. V. HOLMES, F.G.S. (Permanent Vice-President). [At our request, Mr. Holmes has kindly written this short account of the Geology of the Forest District for the information of visitors, and to aid the Curators in arranging a series illustrative of the subject in the Epping Forest Museum.1—Ed.] FOR my present purpose it will be best to consider Epping Forest as the compact district included in the Perambulation of 1641. In other words, we may look on it as having the following bound- 1 The reader may be referred to the under mentioned papers, in addition to those mentioned, on the geology of certain parts of the district, recently printed in The Essex Naturalist : "Geo- logy of the Lea Valley," by T. V. Holmes, vol. viii., p. 198 ; "The Gravels near Barking Side, Wanstead, and Walthamstow," by H. W. Monckton, vol. vii., p. 115 ; "Notes on the Gravels in Epping Forest," by T.
