THE ESSEX FIELD CLUB. 241 Societies and the Control of Plant Extermination," which gave rise to considerable discussion. Mr. R. H. Whitehouse, of Belfast, afterwards read a paper on "The Best Means of Preventing the Extinction of Local Species." After dis- cussion on this paper, the Chairman submitted the following resolution of the Council on the subject in these terms :—" That the British Associa- tion for the Advancement of Science deplores the rapid destruction of fauna and flora throughout the world, and regards it as an urgent duty that steps should be taken by the formation of suitably placed reserves or otherwise, to secure the preservation of examples of all species of animals and plants irrespective of their economic or sporting value, except in cases where it has been clearly proved that the preservation of particular organisms, even in restricted numbers or places, is a menace to human welfare." This was seconded by Sir Edward Brabrook, and agreed to. The Chairman then drew the attention of the Conference to fresh evidence which it was desired to gather regarding the working of the Wild Birds' Protection Acts, and suggested that the various societies represented ought to be able to furnish valuable information to the Departmental Committee, which it was understood would shortly be appointed. Cordial thanks were accorded to Mr. Wilson for the report, and for having represented the Club as Delegate.
