“ The situation of the Forward became really dangerous; in fact, the sea was closing behind her, and in a few hours the ice grew so hard that men could run upon it and tow the brig in perfect safety.
Hatteras, not being able to get around this obstacle, determined to attack it boldly in front. He made use of his strongest blasting cylinders, containing eight or ten pounds of powder. The men would dig a hole in the broadest part of the ice, close the orifice with snow, after having placed the cylinder in a horizontal position, so that a greater extent of ice might be exposed to the explosion ”

“ It went on in this way for thirteen days; the Forward advanced slowly through Penny Strait. The crew murmured, but obeyed; they knew that retreat was now impossible. The advance towards the north was less perilous than a return to the south; it was time to think of going into winter-quarters.
The sailors talked together about their condition, and one day they even began to talk with Shandon, who, they knew, was on their side. He so far forgot his duty as an officer as to allow them to discuss in his presence the authority of his captain. ”

“ The crew waited with folded arms. At last, September 15th, towards three o'clock in the afternoon, the ice-field, having probably run against another one, stopped suddenly; the ship was jarred violently; Hatteras, who had kept his reckoning all along, looked at his chart; he found himself in the north, with no land in sight, in longitude 95°35', and latitude 78°15' in the centre of the region of the unknown sea, which geographers have considered the place of greatest cold. ”

“ How they hurry on, as if they were racing!”
“Besides,” added Johnson, “some carry sharp lances, of which you had better take care, Doctor.”
“It's a real siege,” shouted the doctor. “Well, let us run to the ramparts!” ”
