English title: Transportation of round timber in the Lake Saimaa water system.

This paper aims at investigating which factors, in the point of view of the entrepreneur, define the choice of long-distance transport either as floating in bundles, steamship transport or barge transport in the waterway system of Lake Saimaa in 1950s. It defines the usage, kind of fleet, operation and costs of the abovesaid modes of transport. The investigation is mainly based on statistics of Enso-Gutzeit Oyj and the fuel office of the Finnish State Railways.

Location of the industrial enterprise sets the limits for use of the different modes of transport of roundwood. Previous decisions can influence the future choices, for instance, the capital the company has earler invested on the transportation system. Also, the type and amount of timber acquired by the company, transportation distance, time, and means of transport affect the choice of mode of transport. Those factors that direct decision-making, often lead the entrepreneur to stick to the chosen mode of transport.

Floating becomes the more inexpensive the larger the scale of operation is, and if the timber assortment is suitable for floating and water storage. For instance, dry wood is an asset for a wood export agency, and their sales have often time pressures, which rules floating out of their choices. Transportation in vessels has decreased to 4% of all roundwood haulage, but has its function as a supplementary way of transport.

Veijo Heiskanen. (1950). Tutkimuksia pinopuutavaran proomuun lastauksesta. Acta Forestalia Fennica vol. 58 no. 1 article id 7401. https://doi.org/10.14214/aff.7401
English title: Investigations on loading piled wood into barges.

In Finland, transportation of wood by vessels has decreased, but is still an important mode of transport especially for firewood. In 1941-1947, nearly 25% of the firewood procured by the State Fuel Board was transported by vessels. This investigation concentrates on loading of wood into barges, since the share of wages of total expenses is greatest in this phase. The loading work amounts to nearly 40% of the total wages.

Two methods of loading barges are used in Finland: loading from the shore and truck loading. This study concentrates on the more common method, loading from the shore. A time study was conducted on the different stages of loading and piling wood into barges, most of which is done by hand. Most time-consuming part of the work is transporting the logs to the barge with a wheelbarrow, comprising over 40% of the working time. Time required for loading firewood is almost twice as much as loading pulp wood. Recommendations for loading places and organization of work are given in the article to improve the efficiency of the work.
