The Eastern route they had taken had come to a dead end. With three
days'walk back to the fork to find Arne Saknussemm's original
route, they found their water rations were limited to one day.
Knowing their only change of finding water was on that route, they
set off for the fork and there finally they fell almost lifeless on
the third day. After sleep, they continued down the other tunnel in
their quest for water, and whilst searching on his own, Hans, the
guide, heard the sound of water thundering behind a granite wall,
and, with a pick axe, attacked the wall so as to allow a stream of
boiling water to enter and cool in their tunnel. Not only had they
found life in the water but they had also found a flowing guide to
the Centre of the Earth. They called the stream the Hansbach.
