Free The Practice Effect by David Brin Page B

engine noises. It was puzzling. Perhaps antigravity merited another consideration.
    There was only one way to find out more. He got up and brushed himself off, then shouldered his pack and headed down to town.

    The market outside the city wall was like almost any small riverfront bazaar on Earth. There were shouts and calls and sudden gangs of running boys obviously up to no good. Shops and warehouses gave off pungent aromas, from rich food to the high musk of the grunting draft animals.
    He entered the bazaar with what he hoped was an expression of somebody going confidently about his business. By the variety of clothing he saw, Dennis didn’t feel outlandishly dressed. Boots, shirt, and trousers seemed to be conventional attire here. Some people even carried burdens on their backs, as he did.
    He passed men lounging at the tables of a sidewalk cafe and gathered a few looks. But nobody seemed to stare with more than passing curiosity.
    Dennis began to breathe more easily.
Maybe I can bluff my way all the way to whatever passes for a university in these parts
, he thought hopefully. He had a clear idea of the type of individuals he wanted to contact in this culture.
    Even in ancient and feudal societies on Earth there had always been patches of enlightenment, and these people clearly enjoyed higher technology and culture than that. The aircraft had definitely raised Dennis’s hopes of finding the kind of help he needed.
    The sharp odors of drying fish and tanning hides hit him as he reached the dockyards. The piers were solid-looking structures of dowel and peg construction. They looked almost new, right down to the glossy pilings. The upper surfaces were coated with the same resilient stuff that made up the Coylian roads.
    He stopped to look over one of the boats. Dennis had sailed enough to recognize a sophisticated ship design when he saw one. The hull was thin, light, and sleek. Its mast was stepped elegantly and a little rakishly over the center of gravity.
    Once again, it was built of beautifully glossy laminated wood.
    But if they had the technology to build boats like these, why did they use sails? Did the people of Coylia have some sort of taboo against engines? Perhaps their only machinery was in the factories where they produced these wonderful things.
    Dennis wanted very much to find one of those factories and talk to the people who ran them.
    Not far away, a workgang carried heavy sacks from a warehouse to the hold of a waiting boat. The sacks must have weighed forty kilos each. The stocky, barrel-chested men hummed as they shuffled along the wharf, stooped under their heavy loads.
    Dennis shook his head. Could it be against their religion to use
wheelbarrows
?
    After each stevedore deposited his sack in the hold, he did not return down the narrow ramp but climbed the boat’s gunnels instead. In time with the groaning beat of his comrades, he chanted a brief verse, then dove into the water to make room for the next man.
    It did seem like a good idea, taking a dip before swimming around the pier for another of those heavy loads. Dennis made his way around bales of waiting cargo until he was close enough to hear the chant. It seemed to be a repetitious variant of the phrase
“Ah Hee Hum!
”
    The workers shuffled along to the steady beat. Dennis approached as a giant with a blue-black moustache dropped his load into the hold, then leaped lightly onto the railing. With one hand on the shrouds, he slapped his sweat-glistened chest as the men chanted.
    “Ah Hee Hum!”
    The giant sang:
    The Mayor is wise, but we all know
      The fact is—
    (Ah Wee Hoom?)
    What he misses in wisdom he makes
      Up in mass!
    (Ah Hee Hum!)
    Only two parts of him get enough
      practice—
    (Ah Wee Hoom?)
    One part is his mouth and the
      Other’s his …
    The last part was drowned out by a hasty “Ah Hee Hum!” from the gang. The big fellow let himself fall into the water with a great splash. As
