The aim of the study was to determine how different factors in the stand influence working efficiency in felling. In the eight cutting areas in Northern Finland was harvested a total of 745,200 cubic feet of timber. The factors recorded from the cutting areas were the number of stems per hectare, volume of the stems, quality of the logs (proportion of decayed trees and knottiness of the trees), topography of the site and efficiency of the workers in a team.
The bigger the stems were, the better the result of the workers was. When the size of the stem increased by one cubic ft., the efficiency of the work increased by 2 cubic ft. When knottiness and defects in the stem changed the class describing the quality of a tree by one class, the efficiency decreased by 4.5 cubic ft. The density of the forest affected the time used for loading the timber for hauling. The hauling distance affected the efficiency of the team, which was usually either 2 men and one horse, or 3 men and one horse. If the hauling distance was long, hauling impaired the efficiency. If the distance was short, logging impaired the efficiency of the work. The result show that efficiency of forest work is greatly influenced by the quality of the forest, the trees and the workers.

Forest work in Finland has generally been paid by the job. The wages in 1930s were based on variable measuring units and principles in different parts of the country. The rates did not often take into account how difficult the individual stands are to harvest. The studies have shown that the productivity of logging depends on size of the stems, density of the stand, branchiness of the trees, terrain and depth of snow cover. The article suggests a wage system which takes into account the differences of the cutting areas.
Wages of felling and hauling logs that are payed per the trunk or cubic meter should be adjusted so that the earnings of an employee depends not on the quality of the stand. The quality of the stand influences the stumpage price of the wood, because of the versatile harvesting costs. If the demands of the job in a challenging stand are not compensated for the workers, the higher harvesting costs are inequitably balanced by lowering the wages of the forest workers.

Work in the forestry, for instance, in logging operation during winter, has been important source of employment for the rural population in Finland. The study is based on statistics of forest work, felling, felled timber, workforce and horses used in the forest work in the state forests, published in the annual reports of Metsähallitus (Forest Service) in 1911-1913. The administrative and silvicultural work, for instance, sowing and planting, clearing of the felling area, building forest roads or work in the nurseries, range from 20% to 22% of all work done in the forestry. Major part of the work time is used in felling. To harvest one cubic meter of timber requires 0.3 man-days and 0.2 horse-days. The work is seasonal; felling work is available for about 90-100 days a year. Forest haulage is possible only in the winter, and for instance sowing and planting in the summer. The employees have secondary jobs in agriculture and in other sectors.
