John Mills owned a Pottery Company on the Maylands peninsular in the early part of this century. The clay used for his work was imported from N.S.W. along with the coal and this was transported up the river from Fremantle on a barge called Daisy, towed by the ‘Swan’. When the pipes were manufactured they had to be transported by the two vessels to the Public Works Department where they were tested. Around 1920, local coal and clay was being used and the pipe testing being done on site, the Daisy was no longer required and sank due to neglect and now lies on the bank opposite the Maylands slipyards.. A rudder was found on the shoreward end of this double ended vessel.
