We move further down the hole and it becomes narrower. The water is pushed into gigantic swells, waves half a mile high!

At the top we glimpse something intensely hot in the far distance - the inferno at the center of the Earth? While most of the crew are determined to carry on even if means their death, some of the men want to go back. They are very agitated, and I can't blame them!

Should we listen to what they say and all turn back? Or should we give them a small boat and let them try to get back on their own? Or should we make them stay? We didn't hire "spare" sailors, and might need every man. Or do something else?
