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.
O Near the halfway point, the movement of the
serum by dog teams was going worse than
