On January 29, Edgar Nollner waited in a dark cabin at
Whiskey Creek, close to the halfway point. Suddenly
he sat up. Bells! Was he hearing things? He ran to the
window and found that it was Bill McCarty, who had
tied sleigh bells to his dogs, coming in from the Ruby
relay cabin. Mushers, either by choice or in some
towns by law, often tied bells on their lead dogs to
warn people they were coming up behind them. Edgar
had not expected to hear Bill's bells for several days,
but he wasted no time. He took the serum and started
north along the frozen Yukon River.
