The peatmosses studied occur on the eastern side of the Oslofiord in the environs of the small town of Sarpsborg. The first part of the paper contains the description of the individual mosses. The numbers upon the table correspond to the numbers on the map. The second part treats of the use of the peat as mosslitter and fuel. The last part contains remarks upon the supposed formation of the mosses. The upper 0,5 - 3 metres of the mosses consist of sphagnum which at the surface is in full growth. In most cases one finds under this stratum another, which is more carbonized. The maximum depth is about 7 metres. At the bottom are often found remains of forest consisting of leaf-bearing trees. In some of the mosses occur near the surface chiefly at the borders roots of pine and fir, which show that conifers have extended themselves further over the peatbog than is at present the case. The author leaves unsettled the question of this former extension of the forest being contemporaneous with respect to all the peat-bogs and of its being caused by a dry climate in former times.
