Doctor Dorn stopped to let us think about what he had told us. _Earth Surface_--nothing above but nothing--and nothing beyond nothing--the thought is more than the mind can hold. That men could have lived on such a place is too much to be believed. There were some things written in the Forbidden Books that could not be true, Doctor Dorn said, like the plants called trees that grew to be many times taller than a man; or lakes called oceans that were larger than a thousand Red Lakes together. But even though these and some other things the books said were not possible, there was something about the story of men living on Earth Surface that made him wonder. All sleep he had not slept, but had thought how the old passage we had found near the statue might be one of the surface passages the books told about. He could not imagine any City in the Earth building a passage so steep and so rough. Doctor Dorn stopped talking for a moment, and he looked at me. He seemed very excited. "Jon," he said, "my own feeling now is to take Surface Passage. I cannot do this alone with one lamp. You know how Nina feels. Will you and Nina come with me?" My thoughts must have been like those of the lost-mind men in the hospital at Central City. Even now I do not know why I said we would. Maybe it was because of the way Nina's eyes shone when Doctor Dorn talked about Earth Surface. Nina is a wonderful girl and I love her very much, but sometimes I think I do not understand her completely. Ralf and Mari talked together for a long time. Then Ralf told Doctor Dorn he thought Hope Passage was the best chance for finding life. They would not come with us. Doctor Dorn said he understood. He was sorry we had to separate now, but each must do what was in his own thoughts and heart. Then he asked Bruno if he was coming with us, and Bruno shook his head no, and did not say anything. Theodor thought for even a longer time than Ralf and Mari. He kept biting the nails on his fingers and every little while his eyes would look at Bruno. I knew he was afraid to come with us; but also he was afraid to be alone with Bruno with only Ralf to help him if anything happened. Finally, in a very low voice, he said he would come with us. Doctor Dorn said fine, now there was one more thing we must do before we started. We must take the oil from one of the lamps and put it in the other six lamps so there would be the same amount in each one. Then each group would take three lamps. Theodor said this was not fair. There were four of us so we should have four lamps. Doctor Dorn said four people needed no more light than three people. It was very sad when we had to separate. Mari and Nina cried a little. For a long time after we found Surface Passage and were climbing in it, no one said anything. Perhaps after next sleep, our sadness may be less. * * * * * Twenty-First Awake, 22 Juli 2207
