of sailing. We did not get on farther in a whole month than we should have done in a day, if we had at all a fair wind."
"It strikes me," said the Doctor, "that the temperature keeps getting lower."
"That would be vexing," said Johnson, "for we need a thaw to loosen these packs, and make them drift into the Atlantic. The reason they are so numerous in Davis's Straits is the narrowness of the space between Cape Walsingham and Holsteinberg; but after we get beyond the 67th degree, we shall find the sea more navigable during May and June months."
"Yes; but how to reach it is the question."
"That's it, Mr. Clawbonny. In June and July we should have found the passage open, as the whalers do; but our orders were positive—we were to arrive here in April. That makes me think that our captain is some thorough 'go-ahead' fellow who has got an idea in his head, and is determined to carry it out. He would not have started so soon if he had not meant to go a long way. Well, if we live we shall see."
The Doctor was right about the temperature. The thermometer was only 6° at mid-day, and a breeze was blowing from the southwest, which, though it cleared the sky, considerably impeded the course of the ship, as the strong current it produced drove the loose, heavy masses of ice right across her bows. Nor did all these masses move in the same direction. Some—and those the largest among them—floated in an exactly opposite direction, obeying a counter-current below.
It is easy to understand what difficulty this caused in navigation. The engineers had not a single moment's rest. Sometimes a lead or opening was discovered in an ice-field, and the brig had to strain her utmost to get into it. Sometimes she had to race with an iceberg to prevent the only visible outlet from being blocked up; while again some towering mass would suddenly overturn, and the ship must be backed in an instant to avoid being crushed. Should frost set in, all the accumulation of floe-pieces driven into the narrow pass by the north wind, would consolidate firmly, and oppose an insurmountable barrier to the progress of the Forward.
