English title: Timber transportation of the floating associations in 1922¬‒1927.

 The numerous waterways have promoted the development of forest industry in Finland by offering an easy way to transport timber almost in the whole country. Floating associations arrange the floating for its members. This study, accomplished in the Forest Research Institute, compiles the statistics of the different associations in 1922­‒1927.  The volume of timber transported by the floating associations increased by 40% during the 6-year period, reaching 10.5 million m3 in 1927. The increase has been supported by the number of collectively used floating channels. The number of the floating associations increase from 17 to 26 and the length of the floating channels used by them to 8,300 km in 1922‒1927. About 70‒80% of the transported timber was logs and the 20‒30% small timber. Floated timber comprised 70-80% of the all roundwood used in the forest industry in Finland at the time. Majority of the logs were softwood.
