"That would be a pity," answered Johnson, "for a thaw is necessary to break up these masses and drive them away into the Atlantic; besides, they are more numerous in Davis's Straits, for the sea gets narrower between Capes Walsingham and Holsteinborg; but on the other side of the 67th degree we shall find the seas more navigable during the months of May and June." "Yes; but first of all we must get to the other side." "Yes, we must get there, Mr. Clawbonny. In June and July we should have found an open passage, like the whalers do, but our orders were precise; we were to be here in April. I am very much mistaken if our captain has not his reasons for getting us out here so early." The doctor was right in stating that the temperature was lowering; the thermometer at noon only indicated 6 degrees, and a north-west breeze was getting up, which, although it cleared the sky, assisted the current in precipitating the floating masses of ice into the path of the _Forward_. All of them did not obey the same impulsion, and it was not uncommon to encounter some of the highest masses drifting in an opposite direction, seized at their base by an undercurrent. It is easy to understand the difficulties of this kind of navigation; the engineers had not a minute's rest; the engines were worked from the deck by means of levers, which opened, stopped, and reversed them according to the orders of the officers on watch. Sometimes the brig had to hasten through an opening in the ice-fields, sometimes to struggle against the swiftness of an iceberg which threatened to close the only practicable issue, or, again, some block, suddenly overthrown, compelled the brig to back quickly so as not to be crushed to pieces. This mass of ice, carried along, broken up and amalgamated by the northern current, crushed up the passage, and if seized by the frost would oppose an impassable barrier to the passage of the _Forward_. Birds were found in innumerable quantities on these coasts, petrels and other sea-birds fluttered about here and there with deafening cries, a great number of big-headed, short-necked sea-gulls were amongst them; they spread out their long wings and braved in their play the snow whipped by the hurricane. This animation of the winged tribe made the landscape more lively. Numerous pieces of wood were floating to leeway, clashing with noise; a few enormous, bloated-headed sharks approached the vessel, but there was no question of chasing them, although Simpson, the harpooner, was longing to have a hit at them. Towards evening several seals made their appearance, nose above water, swimming between the blocks. On the 22nd the temperature again lowered; the _Forward_ put on all steam to catch the favourable passes: the wind was decidedly fixed in the north-west; all sails were furled.
