1. Steam sterilization of the tobacco plant bed did not control ringspot. 2. The virus was not transmitted from diseased to healthy plants by the common tobacco flea beetle (Epitrix parvula) although they lived and multiplied on tobacco plants within the cages. 3. The cucumber flea beetle (Epitrix cucumeris), leaf hopper (Empoasa fabea), Aphis (Macrosiphum solanifolii) and the lightning bug (Photinus scintillans) did not survive when caged on tobacco, and no infection was obtained with them. The tobacco worm (Phlegethontius quinquemoculata) survived but did not transmit ringspot. 4. Stick weed, sometimes called yellow crown beard, (Verbisina alternifolia) and sweet clover (Melilotus alba) were found naturally affected with ringspot, infection was readily obtained on tobacco with the expressed juice from these plants. 5. Twenty-five other species of weeds were tested for ringspot with negative results. 6. The rate of spread of the disease was not definitely determined. 7. The percentage of ringspot infection in ten counties in Virginia in 1927 was 2.5. In Washington County in 1928 it was 3 per cent, and in 1929, 7.6 per cent. 8. There was an average injury of 20 per cent to the affected plants 9. It is estimated that ringspot caused a total loss of $12,768.00 in Washington County in 1929. / M.S.

Australia in the early 50s followed a decade or so of frenzy activities in the visual arts. This resurgence of Australian art which led to its recognition in the UK and the United States also brought about a renewed recognition in the quality of domestic architecture. New boundaries in the design of the Australian home were being redefined, both in theory as well as in practice. Although the decades between the two Great Wars saw the importation of such influences as the Californian Bungalow and Art Deco styles (shades of Dudok, Mendelsohn etc.), it was during the post-war years that the term organic architecture that was much discussed by a wide range of practitioners of the time. This research aims to trace the journey of organic architecture from its origin to Australia and provide some insight into the workings of those who claimed to have practiced it.
