Edipon's good mood remained and Jason took advantage of it by extracting as many concessions as possible. By hinting that there might be more traps in the engine permission was easily gained to do all the work on the original site instead of inside the sealed and guarded buildings. A covered shed gave them protection from the weather and a test stand was constructed to hold the engines when Jason worked on them. This was of a unique design and built to Jason's exacting specification, and since no one, including Mikah, had ever heard of or seen a test stand before Jason had his way.

The first engine proved to have a burnt-out bearing and Jason rebuilt it by melting down the original bearing metal and casting it in position. When he unbolted the head of the massive single cylinder he shuddered at the clearance around the piston; he could fit his fingers into the opening between the piston and the cylinder wall; by introducing cylinder rings he doubled the compression and power output. When Edipon saw the turn of speed the rebuilt engine gave his caroj he hugged Jason to his bosom and promised him the highest reward. This turned out to be a small piece of meat every day to relieve the monotony of the krenoj meals, and a doubled guard to make sure that his valuable property did not escape.

Jason had his own plans and kept busy manufacturing a number of pieces of equipment that had nothing at all to do with his engine-overhauling business. While these were being assembled he went about lining up a little aid.

"What would you do if I gave you a club?" he asked a burly slave whom he was helping to haul a log towards his workshop. Narsisi and one of his brothers lazed along out of earshot, bored by the routine of the guard duty.

"What I do with club?" the slave grunted, forehead furrowing and mouth gaping open with the effort of thought.

"That's what I asked. And keep pulling while you think, I don't want the guards to notice anything."

"If I have club, I kill!" the slave announced excitedly, fingers grasping eagerly for coveted weapon.

"Would you kill me?"

"I have club, I kill you, you not so big."

"But if I gave you the club wouldn't I be your friend? Then wouldn't you want to kill someone else?"
