Amateurishly Peter shoveled coal into the little furnace while the stranger in the black cloak juggled with steam-valves and levers, "Don't be worried," he advised Peter, "You'll get the hang of things after a while." He glanced at a watch. "Here we go," he said, yanking the whistle-cord.
The train started off into its tunnel, sliding smoothly and almost silently along, the only noise being from the driving rods, "Why doesn't it clack against the rails?" asked Peter.
"Levitation. Didn't you notice? We're an inch off the track. Simple, really."
"Then why have a track?" asked Peter.
The stranger smiled and said, "Without—" then stopped abruptly and looked concerned and baffled. And that was all the answer Peter got.
"Wake up," shouted the
stranger nudging Peter.
"We're in the war zone!"
"Zasso?" asked Peter, blinking. He had been napping after hours of steady travel. "What war zone?"
"Trolls—you know."
"No, I don't!" snapped Peter. "What side are we on?"
"Depends on who stops us," said the stranger, speeding the engine, They were out of the tunnel now, Peter saw, speeding along a couple of inches above the floor of an immense dim cave. Ahead the glittering double strand of the track stretched into the distance.
"Oh—oh!" muttered the cloaked stranger. "Trouble ahead!" Peter saw a vague, stirring crowd before them. "Those trolls?" he asked.
"Yep," answered the engineer resignedly, slowing the train. "What do you want?" he asked a solid looking little man in a ragged uniform. "To get the hell out of here," said the little man. He was about three feet tail, Peter saw. "What happened?" he asked.
"The lousy Insurgents licked us," said the troll. "Will you let us on the train before they cut us down?"
"First," said the engineer methodically, "there isn't room. Second, I have to keep friends with the party in power. Third, you know very well that you can't be killed."
"What if we are immortal?" asked the troll agitatedly. "Would you like to live forever scattered in little pieces?"
"Second," said Peter abruptly, "you get out of it as best you can." He was speaking to the engineer. "And first, you can dump all the freight you have for Almarish. He won't want it anyway when I'm through with him."
"That right?" asked the troll.
"Not by me!" exploded the engineer. "Now get your gang off the track before I plough them under!"
"Hugo," whispered Peter. With a lazy growl the bandur scorched the nape of the engineer's head.
"All right," said the engineer. "All right. Use force—all right." Then, to the leader of the trolls, "You tell your men they can unload the freight and get as comfortable as they can,"
"Wait!" interjected Peter. "Inasmuch as I got you out of this scrape—I think—would you be willing to help me out in a little affair of honor with Almarish?"
"Sure!" said the troll. "Anything at all. You know, for a surfacedweller you're not half bad!" With which he began to spread the good news among his army.
Later, when they were all together
