One day, a little before noon, while lunch was being cooked, the sun broke through the clouds, and for upward of half an hour the ice-pack was one blinding, diamond glitter. Bennett ran for his sextant and got an observation, the first that had been possible for nearly a month. He worked out their latitude that same evening.
The next morning Ferriss was awakened by a touch on his shoulder. Bennett was standing over him.
"Come outside here a moment," said Bennett in a low voice. "Don't wake the men."
"Did you get our latitude?" asked Ferriss as the two came out of the tent.
"Yes, that's what I want to tell you."
"What is it?"
"Seventy-four-nineteen."
"Why, what do you mean?" asked Ferriss quickly.
"Just this: That the ice-pack we're on is drifting faster to the north than we are marching to the south. We are farther north now than we were a month ago for all our marching."
