The Underwood Milk Preserving Works
The Underwood Milk Preserving Works (W. T. Murray and Co., Limited, proprietors), Wallacetown. These works were established in 1892, by the late Mr Robert Blair, and have been owned by the present company since 1896. There are two boilers, each of forty horse-power nominal, a power engine, and a Linde-British freezing machine. Large quantities of milk are received from the surrounding districts, and the principal portion is preserved in tins. The output for a single year has been as high as 40,000 cases of four dozen each, of which a large proportion is consumed in the colony, and the balance exported. From thirty to thirty-five hundredweight of sugar is used daily in the preserving process, and 100,000 gallons of cold water in condensing. The preserving plant is complete in every respect, and includes tin and box-making machinery, and there is also a butter-making department equipped with all the latest appliances. From fifty to sixty persons are employed at the works.
