THE progress of scientific forestry in Norway forms the subject of an interesting article, by Mr. S. Burtt Meyer, in No. 5 of the Journal of the Board of Agriculture. No less than 21-4 per cent, of the total area of Norway is under forest, as against 3.9 per cent, in the United Kingdom. The most abundant forest tree is the Scots pine (Pinus Sylvestris), followed by the birch and the spruce (P. excelsa). The alder, aspen, and rowan are distributed pretty generally, while the oak, ash, elm, and beech are also found in favoured areas. The commercial timbers, however, are the Scots pine and the spruce, the latter being of great importance since the introduction of the wood-pulp trade. Spruce forms much the best material for wood pulp. A certain amount of pine can be added, but more than about 15 per cent, tends to spoil the colour. Spruce grows at a lower altitude than pine, and, generally speaking, in a more southern latitude. South of Trondhjem the pine usually ceases at about 2600 feet above sea-level, where it is replaced by the birch; above 3500 feet only dwarf birch and willow occur, while at some 4000 feet the snow-line stops all vegetation. The best forest land is that lying in the neighbourhood of Christiania extending north and north-east over the Glommen watershed. The management of the forest is on the whole good, and well adapted to the local conditions. The work of felling and removing the timber commences in autumn and continues throughout the winter, being greatly facilitated by the snow which covers the ground from November until March or April.
