we kept more below deck; when the weather was finer we lived more in the open air, often paying visits to the observatory in the ice-house, and among the Chukches living in the neighbourhood, or wandering about to come upon, if possible, some game." The snow which fell during winter consisted more generally of small simple snow-crystals or ice-needles, than of the beautiful snow-flakes whose grand kaleidoscopic forms the inhabitants of the north so often have an opportunity of admiring. Already with a gentle wind and with a pretty clear atmosphere the lower strata of the atmosphere were full of these regular ice-needles, which refracted the rays of the sun, so as to produce parhelia and halos. Unfortunately however these were never so completely developed as the halos which I saw in 1873 during the sledge-journey round North-east Land on Spitzbergen; but I believed that even now I could confirm the correctness of the observation I then made, that the representation which is generally given of this beautiful phenomenon, in which the halo is delineated as a collection of regular circles, is not correct, but that it forms a very involved system of lines, extended over the whole vault of heaven, for the most part coloured on the sun-side and uncoloured on the opposite side, of the sort shown in the accompanying drawings taken from the account of the Spitzbergen Expedition of 1872-73. [Illustration: REFRACTION-HALO. Seen on Spitzbergen in May 1873, simultaneously with the Reflection-halo delineated on the following page. ] Another very beautiful phenomenon, produced by the refraction of the solar rays by the ice-needles, which during winter were constantly mixed with the atmospheric strata lying nearest the surface of the earth, was that the mountain heights to the south of the _Vega_ in a certain light appeared as if feathered with fire-clouds. In clear sunshine and a high wind we frequently saw, as it were, a glowing pillar of vapour arise obliquely from the summits of the mountains, giving them the appearance of volcanos, which throw out enormous columns of smoke, flame-coloured by the reflection from the glowing lava streams in the depths of the crater. A blue water-sky was still visible out to sea, indicating that open water was to be found there. I therefore sent Johnsen the hunter over the ice on the 18th December to see how it was. In three-quarters of an hour's walking from the vessel
