fleshy masses were spotted, and some cheer returned.
    Barthel watched the temperature rise on the ship's thermometers as they entered the region of the Ocean Obelisk. He frowned each time he stood at the base of the mainmast, where the instruments were mounted on a mahogany plaque. He scratched his head and squinted comically. Then, when the Obelisk was in plain view, just before nightfall as the sky dimmed and turned gold and green, his frown cleared. He looked at the thermometers with astonishment and started to shout.
    “It's simple!” he yelled. “It's so beautifully simple!”
     
     
     
     
     
     

Hegira

Twelve
    Bar-Woten and Kiril took turns leaning on the wrench, grunting and straining in the close dark heat of the engine room bilge. The wrench was wrapped around a fist-sized nut that held a tension plate in position, keeping a secondary rod on the high-pressure cylinder in line with its swing alley. It had been rubbing for a day, causing a hideous screech with each pump and swing that echoed through the engine and made the crankshaft tremble and buck. With the gradual loosening of the nut the tension plate could be shifted by deft hammer blows until the cylinder rod crept back into line. It was rough, filthy work with old paint rubbing off on their pants and sweat flooding over their cotton brow-bands and prickling in their eyes. They set the wrench and hammer down for a rest. Bar-Woten rubbed the blisters on his hand.
    Feet banged down the ladder from the upper engine room catwalk. “I've figured it out!” Barthel shouted. “I've got it!”
    He sat down next to them on one of the main bearings, squirming on the uneven surface, and told them. It came out in a quick and happy babble, in Mediwevan, which most of the attending engine hands didn't understand, leaving them to sit and listen blankly on the port stringer beam and bilge keelson.
    “That means the Obelisks have light and heat on top,” he concluded. “That explains why some deep canyons are dark the same way all the time and others aren't.”
    Bar-Woten nodded, too tired to think. Kiril leaned against a condenser pipe and said it sounded convincing.
    “It's very important,” Barthel said, disappointed that his excitement wasn't communicating itself. He looked from face to face and tried to explain it to the other sailors in broken Teutan. They nodded agreeably. Frustrated, he stood and brushed his pants off, turned around, and looked at the engine as though he distrusted it and all other deaf and dumb things he couldn't explain himself to. He climbed out of the engine-well and went about on deck to look for Avra.
    Kiril and Bar-Woten switched with another pair of sailors, and the wrenching and hammering continued.
    The water became warmer and more turbulent. Great spouts tore the sea into ragged shards to the west. In a few days the water cooled slightly, but the temperature increased the closer they approached the Ocean Obelisk.
    Avra helped Barthel put his theory into writing, and together they gathered facts and figures to back it up. He was disappointed to find the idea wasn't original with him, but he still worked to prove his assertions, and Avra tutored him on how to go about the research.
    The Ocean Obelisk passed on the port side the day after the engine overhaul was completed. Kiril watched it from the railing and thought about Barthel's theory, wondering how correct he was. His world was taking shape more each day. He thought he might have it all in the palm of his hand in a few more years. The Obelisks were higher than the air, and the sun did not rise or set on the Second-born, but grew bright or dim, and perhaps hid where nothing but its light could be seen ... He daydreamed for an instant, and the Obelisk turned scaly and writhed like the tail of a dragon. He shook his head briskly to clear it. In a week the Obelisk was in the horizon haze.
    The smell of the sea changed as they approached the waters of the Bicht. Islands grew more
