237 THE CORRESPONDING SOCIETIES' COMMITTEE OF THE BRITISH ASSOCIATION, YORK, 1906. REPORT OF THE CLUB'S DELEGATE, F. W. RUDLER, I.S.O., F.G.S,, Secretary of the Conference of Delegates. [Read November 24th, 1906.] AT the first meeting of the Delegates held under the chairmanship of Sir Edward Brabrook, C.B., who fitly represented the new group of "Associated Societies," the chief subject for discussion was that of Meteorology. Dr. H. R. Mill, the distinguished authority on rainfall, introduced the subject by an admirable address, in which he commended the study of meteorology as one peculiarly fitted for cultivation by provincial societies, inasmuch as it needed for its prosecution comparatively simple appliances, whilst it developed habits of strict accuracy and method in the observers. At the same time it contributes to the advancement of knowledge in directions much needed. The determination of local climate can be best effected by the work of local societies, since it requires long continuous records usually beyond the power of individual observers. Dr. Mill remarked that a society should be, by its nature, immortal—a remark which, it is hoped, may be applied to the Essex Field Club. But as our Club does not contemplate the formation of a meteorological station the subject need not be enlarged upon. Of more direct interest to the Club were the proceedings at the second meeting. This was held under the chairman- ship of Mr. John Hopkinson, for many years the honorary secretary of the Hertfordshire Natural History Society, and was attended by the President of our Club. The main subject of discussion at this meeting was that of County Photographic Surveys, which was introduced by Mr. W. Jerome Harrison, of Birmingham. In an elaborate paper Mr. Harrison traced the history of the survey movement, which was really initiated by him, when, in 1889, he. proposed a photographic survey of Warwickshire. From Warwickshire the work has spread, and surveys are now in active operation in Worcestershire, Kent, Surrey, Yorkshire, and Edinburgh, as well as in Essex. Mr. Victor Taylor had kindly sent your delegate some notes on the photographic survey of Essex, which he used. Mr. Harrison
