The consumption of wood and the value of the wood in the forest manufacturing industry in 1925‒1935 was studied using the official industrial statistics as the main source of data. The annual wood consumption of sawmills, plywood industry, match production, wood-wool industry, spool production, mechanical pulp mills, sulfite pulp mills and sulfate pulp mills was in average 15.6 million cubic meters, of which 4.0 million m³ was pulpwood, 11 million m³ saw logs and 0.44 million m³ veneer timber. The spool production used 163,200 m³, match production 39,900 m³ and wood-wool production 7,900 m³ of wood. When the wood consumption is at its maximum levels, the fellings cannot be increased sustainably. Thus, the sawing cannot be increased from the present level. The growth of pulp industry has created demand for small timber, and in that industry there is room for expansion.

The article presents six fasciations found in Finland on bird cherry trees. Based on the literature it seems that fasciations are the precondition for witches’ brooms. The witches’ brooms on bird cherry trees are rare, but they have been mentioned in literature. Some views on their occurrence and development are represented. Also the possible causes behind the developments are discussed based on literature.

The financial accounting of the forestry needs redefining in Finland due to the effect of forest improvement, especially peatland drainage, on timber balance and valuation of forest land. The aim of the study was to develop methods to determine the timber balance using a separate forest land account. The problems of timber balance are related to the technical methods to assess timber balance and the cost of the work, quantitative determination of the profit, and qualitative determination of the profit. One main problem is to whether to define the quantitative profit as a sustainability of timber resources or difference in the allowable cut and outturn. The article discusses the strengths and weaknesses of the methods, and concludes that regardless of the method that is used to calculate the timber balance, profit or loss accounts have less exact nature in forestry than in other sectors. Replacing reliably calculated revenue surplus with operating result based on timber account would lead to tentative results.
