CONFERENCE OF CORRESPONDING SOCIETIES. 17 Mr. M. C. Duchesne read an elaborate paper on "Afforestation," a subject the importance of which had been emphasised by the war. He treated of the National timber demands, and of what had been done (or not done) for them, and alluded to the proposals of the Forestry Sub- committee of the Reconstruction Committee, himself suggesting a larger scheme as advisable, with more help from the state. He held that the obligation to ensure reserves of timber lies not only with landlords, but with the various consumers of timber. It is due to private owners, who have kept up their woods in spite of difficulties and without state assistance, that reserves of native timber have been available for war-purposes; and he asks for the removal of various handi- caps to the production of timber, and for the co-operation of scientific and practical men. The importance of the subject of a regular supply of tree-seeds was noticed and nursery-work was treated of, allusion being made to the possibilities of woman-labour. This paper, by an expert, was very well received, and led to a good discussion, in which Sir Charles Bathurst, M.P., took part, saying that Mr. Duchesne deserved thanks for the way in which, for years, he had advocated the claims of forestry. Your delegate made some more-or-less relevant remarks, in which he was supported by the President. In his reply, the author said that he was in favour of an Arbor Day, as suggested by Mr. J. Hopkinson, and offered to communicate with the secretary in the matter of tree-seeds, so that the various societies might help in collecting them. A resolution was passed to the effect that trees should be planted on Arbor Day by the delegates and other members. A Typomap, by Mr. P>. B. Woodward, was exhibited. Its object is to enable occurrences of species to be recorded with approximate, geographic accuracy, without the expense of specially-engraved maps. A summary of a paper by Mr. P. Westall, on "Grants to Regional Museums" was read by the Secretary; but there was no time 10 discuss it. The need for such grants was impressed on the author dining the formation of the Museum at Letchworth Garden City, which was founded by the local Natural History Society. Such museums serve not only their society, but also the public and schools; so that they deserve outside support. Rare Essex Bryophytes—Mr. F. W. Thorrington has presented to the Club's Herbarium at the Stratford Museum, specimens of Plagiochila asplenioides (L.) Dum., from Woodham Walter Common, and Fissidens incurvus, Starke, from Horn- church, both gathered as long ago as 1912. The former is believed to be a new record for the county, and the latter for the southern vice-county.—Percy Thompson, May, 1919.
