Replenished with the water the journey continued with haste, but somehow they find themselves separated. Professor Lidenbrook's nephew Axel found himself alone. His mind was seized with unparalleled fear and he saw memories of home flashing before him. His fiancee Grauben, his house and friends in Hamburg. He saw hallucinations of all the incidents of the journey. And, unworthy as he felt, he knelt in fervent prayer and then, in panic, e ran blindly through a tunnel only to reach a dead end, where he fell panting for breath. In the darkness he cried... voices... voices... voices... He heard voices. He heard his uncle's voice. Due to the shape of the gallery and the conducting power of the rocks, his uncle's voice was uncannily travelling around the walls. By means of their chronometers they discovered they were four miles apart, so Axel set about the task of rejoining the Professor and their guide.
