Timber Floating and Rafting: The transportation of logs bound together to form rafts was common in Austria until the 19th century. Salt and iron were also transported in this way on the Danube and its tributaries; after the goods arrived, the rafts were disassembled and the logs sold. Wooden rafts were also common on smaller rivers and streams which were dammed for this purpose (gorges). In the 18th and 19th centuries Vienna was provided in this way with timber and fire wood. After the railway system was built, the practice of using rafts for transportation purposes became obsolete.
