    A survey of farm water supplies in central parts of Victoria 1956-7
    De Laine, Robert James. (University of Melbourne, 1959)
    The aim of this survey was to assess the present level of stock and household water facilities on farms in a selected area of Victoria. 149 farms, chosen at random from 5 shires lying in the 20.25 inch rainfall country between Stawell and Benalla, were visited. Details of all the features associated with the collection, storage, and use of both stock and household water were obtained for each of these farms. In order that the standard of stock water supply could be compared with the management of the rest of the farm, personal particulars of each farmer and general details of the farm were also recorded. The survey found that the majority of farms had inadequate provision for stock water, for example 60% of the farms visited were unable to water more than 60% of their farm area, when stocked at the rate of 1 sheep to the acre. It was also found that the standard of household water was low, for example, 28% of farms were restricted to 10 gallons per person per day, or less.

    Studies on plant pathogenic bacteria with emphasis on serological identification
    Naylor, Jill. (University of Melbourne, 1954)
    The major problem in the recognition of bacterial diseases of plants, and hence their prevention or cure, is the rapid isolation and identification of the causal organism from the infected host. Although isolation procedures are adequate, provided the diseased organ is not heavily infected with secondary invaders, the identification of the phytopathogen is very difficult as is its distinction from saprophytic species. Because of these difficulties, this investigation was commenced in order to study the present methods of classification, and the prospects for using serological tests in the rapid identification of phytopathogenic bacteria.

    The biology of the silverfish, Ctenolepisma longicaudata, esch. with particular reference to its feeding habits
    Lindsay, Eder A. (University of Melbourne, 1939)
    The long-tailed silver fish - Ctenolepisma longicaudata, Escher. - is the only common species in houses in Australia. Materials normally eaten have "been determined from an examination of their crop contents. The cause of the selective attack on certain household goods, including wallpaper and writing paper, hag been examined, and a protective spray of tricresylphosphate in petroleum solvent prepared. The effect of temperature and humidity on the stages of the life cycle is described and methods of control are outlined.

    The effect of air-drying on the level of extractable manganese and cobalt in the soil
    Zende, G. K ( 1953)
    The work presented here, was carried out to study' mainly one side of the problem, namely the slow reduction of manganese oxides by the organic matter during the process of air-drying. The other possibility - colloidal effect - needs further investigation. The effect of air-drying was studied In two alkaline soils and four acidic soils, limed to different pH. From the consideration of these results, the following conclusions can he drawn. (1) The effect of air-drying on the extractable manganese is seen only in soils with pH less than 6. (2) The effect is dependent on the amount of active manganese oxides and the amount of organic matter. (3) The, kind of organic matter and the nature of the oxide contribute to the effect of drying (but some further work is necessary.). Cobalt was included to check these factors with the assumption that it will behave as an unoxidized model for Mn. In general, there is no increase in the level of extractable cobalt after drying. Introduction of cobalt raised some new problems and an attempt was made to get some Information on the various aspects of the chemistry of, cobalt In the soil.
