Documenting the accidental discovery of successful oyster cultivation in the Conwy mussel tanks, which led to the experiments of the 1920s and the building of special heated oyster tanks below the mussel tanks. Opens with a quotation from G Bouchon Brandely (1886) referring to the seductiveness of the idea of keeping and raising embryo oysters in closed waters. Primarily of scientific interest [includes many photographs of oysters in varying stages of growth], the album also includes many site pictures with tanks in varying stages of completion; members of staff carrying out the tasks involved in rearing oysters artificially; Dr Dodgson with contractors building the oyster culture tanks; a small number of pictures re mussel fishing; the installation of heating equipment for the oyster tanks; oyster pools in the Conwy Estuary; oyster beds in the Menai Straits, pa. Llanidan; the boat 'Himalaya'; the laboratory and office at Castle Bank, Conwy; equipment used in the culture experiment of 1924.
