The air grew colder, and, July 19th, fell as low as 26°; the next day was warmer, but this harbinger of the arctic winter warned Hatteras not to linger longer. The wind seemed to blow steadily from the west and delayed his progress. And yet he was in haste to reach the point whence Stewart saw an open sea. The 19th he resolved to enter the channel at any price; the wind blew dead against the brig, which, with her screw, could have made headway against the violent snow-squalls, but Hatteras had before all to be economical with the fuel; on the other hand, the channel was too broad to permit of the brig being towed.
