At the height of the river trade, there was a town surveyed and laid out, and streets were named. This town was to house the workers at the river port of Red Bank when the paddle steamers plied the Murray River as far as Albury, carrying produce such as wool and wheat to the various towns along the river in the 1800s. As the river trade died away, this town never went ahead – one might say, “The town that never was.” A lone gum tree stands on the site today.This item is significant because it documents plans which were made for the early development of Wodonga.A black an white map depicting the proposed location of the township.

Letter dated November 12, 1937 to Paul A. Douden & Co. from W. W. Eden, Mgr. F. W. Woolworth Co. W. W. Eden mentions that since installing Scale Buoys over two years age we have had no trouble from scale or lime deposits at all in our system, except for the water used for cooling the natural gas engines. This water didn't come in contact with the Scale Buoys and they contemplated additional units to treat it. They also had no scale in the coffee makers and dish washers.sciences, instruments - general, scalebuoy, bill ashman collection, f w woolworth co, paul a douden & co, scale buoys, w w eden

This scale model of a mining plant was made by Donald Douglas Mather of Talbot. The engine shed houses the winches, which raise and lower the cages carrying the workmen. The winches also control the water-Baling tanks, which are lowered into the pump shaft to clean the water. The Pump Shaft is part of the main shaft partitioned off for keeping the water down. The old style plant (or cas commonly known poppet legs), were all of timber construction and, when erected, straddled the main shaft. This scale model allows for steel construction, and is set over the shaft to permit an unobstructed view of the operations. The Bad level is where the workmen enter and leave the shaft. The staging platform on the first level is where the trucks and mullock or other material are wheeled out on rails and then tipped to form the mine dump. The top level is to allow for maintenance of plant. Donald Douglas Mather of Talbot worked in mines in Ballarat, and made the model of the poppet head. The poppet head is a replica of those used at many mines in Ballarat. Back in the 1850s Ballarat was a god rush town and many mining claims were made and poppet heads built this is a replica of those poppet heads which are a part of Ballarat's Heritage and a full size poppet head is erected at Sovereign Hill Theme Park in Ballarat. Mining is a huge part of Ballarat's history.A timber poppet head and engine room model.
