THE ESSEX FIELD CLUB. 311 The meeting concluded with a vote of thanks to the conductors, proposed by the President, which was heartily accorded by those present. The return walk to Loughton, through the darkened forest, under a clear starry sky, with the crescent moon sinking behind the black tree- masses, was not the least enjoyable part of a pleasurable day. ORDINARY MEETING (523rd Meeting). Saturday, 27TH November, 1920. This meeting was held at 3 o'clock on the above afternoon in the Municipal Technical Institute, Stratford, the President, Mr. Robert Paul- son, F.L.S., F.R.M.S., in the chair. The attendance was 42. The following persons were elected Members of the Club:— Lady Lloyd, of Roll's Park, Chigwell. Miss C. Osmond, B.Sc., of 36, Hanley Road, Finsbury Park, N.4. Miss Winifred Smith, B.Sc., of University College, Gower Street, W.C.1. Mr. Alfred Bell, of Oakland House, Cringleford, Norwich. Mr. John Avery exhibited a further series of Essex prints. The Curator exhibited a fine polished section of trunk of walnut (Juglans regia), which had been presented to the Club's Museum by Mr. Walter Fox, who contributes the following account of the exhibit. The section came from one of seven trees which were growing near an old farm house, known as "Frizlands," Dagenham, and are believed to have been planted by one Joseph Joyner some 3 or 4 years after he came to reside there in 1790. Joyner came from West Thurrock and purchased the Manor of Frislings, as it was then known. The mansion in those days must have been of considerable size, but the building has been reduced and the old parts incorporated with what is now a moderate and unpre- tentious farm house. A novel feature about the house is an arrangement of strong rooms in the basement, which were built by Joyner to store money, valuables and documents. Joyner was a banker, carrying on business at Romford Town (reputed to be the first bank in that town), and made it a practice to bring over daily, after business hours, all monies and docu- ments to "Frizlands" for safety. The bank is now one of the numerous branches of "Lloyds." The Curator also exhibited a fine specimen of the Great Northern Diver (Colymbus glacialis), shot in Iceland about 1888, and in full summer plumage, which had just been presented to the Club's Museum by Sir Rickman Godlee. Mr. Thompson further exhibited two Cornish Choughs (Pyrrhocorax graculus) which he had recently acquired for the Museum by purchase. Mr. Miller Christy remarked on the disappearance from the Cornish cliffs of these birds which he ascribed to interference by jackdaws, which were increasingly numerous. Miss G. Lister exhibited a rhizomorph of the agaric, Armillaria mellea, and also, under a microscope, a section of the root of the Bird's nest Orchis, showing the mycorhiza or fungus-hyphae in the cortical cells ; she remarked that this constituted an example of "two-sided parasitism," as the mycorhiza enter the root of the orchid and feed on the carbohy-
