On the 28/17th April, 1769, there was a storm from the south-west, with mist, rain, and hail as large as half a bullet. On the 2nd June/22nd May a dreadful wind raged from the north-west, bringing from the high mountains a "sharp smoke-like air,"--it was certainly a _foehn_ wind. The painful, depressing effect of this wind is generally known from Switzerland and from north-western Greenland. At the latter place it rushes right down with excessive violence from the ice-desert of the interior. But far from on that account bringing cold with it, the temperature suddenly rises above the freezing-point, the snow disappears as if by magic through melting and evaporation, and men and animals feel themselves suffering from the sudden change in the weather. Such winds besides occur everywhere in the Polar regions in the neighbourhood of high mountains, and it is probably on their account that a stay in the hill-enclosed kettle-valleys is in Greenland considered to be very unhealthy and to lead to attacks of scurvy among the inhabitants. The crew remained during the winter whole days, indeed whole weeks in succession, in their confined dwellings, carefully made tight, without taking any regular exercise in the open air. We can easily understand from this that they could not escape scurvy, by which most of them appear to have been attacked, and of which seven died, among them Tschirakin. It is surprising that any one of them could survive with such a mode of life during the dark Polar night. The brewing of _quass_, the daily baking of bread, and perhaps even the vapour-baths, mainly contributed to this.
