En resa till norra ishafvet sommaren 1892, företage af vegastipendiet.[A Journey to the Arctic O the Summer 1892, made with the aid of the V By AXEL HAMBERG. Reprint from Ymer, 189 The author accompanied a Norwegian sealer visitin and the Spitzbergen Islands. In King's Bay a stay of several days was made, and the author studied some ice fields, which he named Lovèns névés. On the surface of the ice at this place but few small lateral moraines were to be seen, but in a fracture of the ice an inner moraine was observed. This consisted of about ten strata of assorted gravel and sand alternating with layers of ice. It was evidently a medial moraine in the lee of a projecting low mountain top, seen several miles inland. It is stated that similar features are common in the ice fields of these arctic islands. The author suggests that, if the ice were melted away, such moraines would give rise to structures much resembling åsar, both as to the contained material and as to the form and direction of the resulting topography. At one place some of these deposits were seen extending a distance at right angles away from the ice margin and resembling somewhat the Scottish kames. The névés were composed of bedded ice, in some places extending out in the sea. In several instances it had been melted away under the water and marginal blocks had evidently been detached by their own weight, leaving the edge of the ice standing in vertical smooth walls as if" cut off with a knife." A number of photographs were taken with a camera fitted for photogrammetric measurements and a map constructed from these photographs accompanies the paper. The névés represented on this map are seen to occupy valleys among several small groups of hills and extending to within less than a mile from the shore. The front edge of the ice sometimes forms an evenly rounded curve and sometimes a vertical cliff from 60 to 100 feet high. It is suggested that this difference in the behavior of the terminal edge (when resting on the land) may be due to a difference in the morainic material of the
