Timber rafting is a log transportation method in which logs are tied together into rafts and drifted or pulled across a water body or down a flatter river. It is arguably the second cheapest method of transportation of timber, next after log driving. Both methods may be referred to as timber floating. ==Historical rafting== Unlike log driving, which was a dangerous task of floating separate logs, floaters or raftsmen could enjoy relative comfort of navigation, with cabins built on rafts, steering by means of oars and possibility to make stops. On the other hand, rafting requires wider waterflows. Timber rafts were also used as a means of transportation of people and goods, both raw materials (ore, fur, game) and man-made. Theophrastus (''Hist. Plant.'' 5.8.2) records how the Romans imported Corsican timber by way of a huge raft propelled by as many as fifty masts and sails.〔Casson, Lionel (1995): "Ships and Seamanship in the Ancient World", Johns Hopkins University Press, ISBN 978-0-8018-5130-8, p. 4, fn. 2〕 This practice used to be common in many parts of the world, especially North America and on all main rivers of Germany. Timber rafting allowed for connecting large continental forests, as in south western Germany, via Main, Neckar, Danube and Rhine with the coastal cities and states, early modern forestry and remote trading were closely connected. Large pines in the black forest were called „Holländer“, as they were traded to the Netherlands. Large timber rafts on the Rhine were 200 to 400m in length, 40m wide and consisted of several thousand logs. The crew consisted of 400 to 500 men, including shelter, bakeries, ovens and livestock stables.〔(Beschreibung eines großen Rheinfloßes )〕 Timber rafting infrastructure allowed for large interconnected networks all over continental Europe. The advent of the railroad, steam boat vessels and improvements in trucking and road networks gradually reduced the use of timber rafts. It is still of importance e.g. in Finland. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「timber rafting」の詳細全文を読む スポンサード リンク
