Meanwhile "Wild Bill" faced a number of problems. The
temperature had dropped to fifty degrees below zero. Speed
was important, but he could not push his team too hard. The
dogs' lungs might frost from breathing heavily in the Arctic
air. To protect his own lungs, Bill breathed only through his
nose. The bitter wind howled and hurled snow in his face.
The trail was a blur.
The only choice Bill had was to move as quickly as
possible.
Bill did not understand how to handle the cold Arctic
weather.
Moving too quickly could cause Bill and his dogs to
become ill or die
Bill could not see the trail because of how quickly his
team was moving
