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.
The doctor could not miss such an occasion of getting wet to the skin; he remained on deck, a prey to that emotional admiration which a scientific man must necessarily feel during such a spectacle. His nearest neighbour could not have heard him speak, so he said nothing and watched; but whilst watching he was witness to an odd phenomenon, peculiar to hyperborean regions. The tempest was confined to a restricted area, and only extended for about three or four miles; the wind that passes over ice-fields loses much of its strength and cannot carry its violence far out; the doctor perceived from time to time, through an opening in the tempest, a calm sky and a quiet sea beyond some ice-fields. The Forward would therefore only have to take advantage of some channels left by the ice to find a peaceful navigation again, but she ran the risk of being thrown on to one of the moving banks which followed the movement of the swell. However, in a few hours Hatteras succeeded in getting his ship into a calm sea, whilst the violence of the hurricane spent itself at a few cables’ length from the Forward. Melville Bay no longer presented the same aspect; under the influence of the winds and the waves a great number of icebergs, detached from the coast, floated northward, running against one another in every direction. There were several hundreds of them, but the bay is very wide, and the brig easily avoided them. The spectacle of these floating masses was magnificent; they seemed to be having a grand race for it on the open sea. The doctor was getting quite excited with watching them, when the harpooner, Simpson, came up and made him look at the changing tints in the sea; they varied from a deep blue to olive green; long stripes stretched north and south in such decided lines that the eye could follow each shade out of sight. Sometimes a transparent sheet of water would follow a perfectly opaque sheet.
“Well, Mr. Clawbonny, what do you think of that?” said Simpson.
“I am of the same opinion as the whaler Scoresby on the nature of the different coloured waters; blue water has no animalculae, and green water is full of them. Scoresby has made several experiments on this subject, and I think he is right.”
“Well, sir, I know something else about the colours in the sea, and if I were a whaler I should be precious glad to see them.”
“But I don’t see any whales,” answered the doctor.
“You won’t be long before you do, though, I can tell you. A whaler is lucky when he meets with those green stripes under this latitude.”
“Why?” asked the doctor, who always liked to get information from anybody who understood what they were talking about.
“Because whales are always found in great quantities in green water.”
“What’s the reason of that?”
“Because they find plenty of food in them.”
“Are you sure of that?”
“I’ve seen it a hundred times, at least, in Baffin Sea; why shouldn’t it be the same in Melville Bay? Besides, look there, Mr. Clawbonny,” added Simpson, l............
