the mills were located in the forest and tramways linked them to the railway station. henry collins set up his mill in mill road south-east of yinnar around 1911 and built a tramline along whitelaw's track. higher in the strzeleckis, where mountain ash forests grew, settlers burnt the trees they had ringbarked and felled, although some were split for palings. during the 1920s, there were advances with kiln drying mountain ash and it became highly sought after as a building timber. small sawmills such as the duff sawmill operated in the higher part of the strzeleckis until the timber became too difficult to extract.
