Melville Bay, though easily navigable, was not free from ice; ice-fields lay as far as the utmost limits of the horizon; a few icebergs appeared here and there, but they were immovable, as if anchored in the midst of the frozen fields. The _Forward_, with all steam on, followed the wide passes where it was easy to work her. The wind changed frequently from one point of the compass to another. The variability of the wind in the Arctic Seas is a remarkable fact; sometimes a dead calm is followed in a few minutes by a violent tempest, as the _Forward_ found to her cost on the 23rd of June in the midst of the immense bay. The more constant winds blow from off the ice-bank on to the open sea, and are intensely cold. On that day the thermometer fell several degrees; the wind veered round to the south, and violent gusts, sweeping over the ice-fields, brought a thick snow along with them. Hatteras immediately caused the sails that helped the screw to be furled, but not quickly enough to prevent his little foresail being carried away in the twinkling of an eye. Hatteras worked his ship with the greatest composure, and did not leave the deck during the tempest; he was obliged to fly before the weather and to turn westward. The wind raised up enormous waves, in the midst of which blocks of ice balanced themselves; these blocks were of all sizes and shapes, and had been struck off the surrounding ice-fields; the brig was tossed about like a child's plaything, and morsels of the packs were thrown over her hull; at one instant she was lying perpendicularly along the side of a liquid mountain; her steel prow concentrated the light, and shone like a melting metal bar; at another she was down an abyss, plunging her head into whirlwinds of snow, whilst her screws, out of the water, turned in space with a sinister noise, striking the air with their paddles. Rain mixed with the snow and fell in torrents.
