Here we have the rhythm of the book, which resembles the surface of a pond disturbed by a thrown pebble. Anyway, there are screws in Ramelli''s book, presuming absent screwdrivers, and we have retreated another century.De Re Metallica backs up again, to 1556, with the illustration of a slotted screw to attach the leather to a bellows. An illustrated manuscript of 1475 to 1490--a sort of household manual for a castle--shows slotted screws fastening a leg iron and a pair of manacles--castle staples. This train of thought leads the author to war, a great stimulus to invention, witness radar and the jet engine. Pollard''s History of Firearms illustrates a fifteenth-century German equivalent of the sawed-off shotgun in which the stock is screwed to the metal. Research in the Metropolitan Museum of Art turned up a screw of the 1480s attaching parts of a suit of armor. Screws were slotted with a hacksaw and the threads were filed by hand until, in 1760, Job and William Wyatt in Staffordshire patented a machine that turned out more consistent screws at the rate of one about every six seconds. The author comments that, a century before the industrial revolution, "their factory was the earliest example of an industrial process designed specifically to shift control over the quality of what was being produced from the skilled artisan to the machine itself"

Martz, who produces grain and livestock on a 430-acre farm, was using a pair of 300-gallon tanks on overhead stands for gasoline and diesel storage. The facility, shown on the next page, was typical of systems on many farms. However, while serving on the Boone County Soil and Water Conservation Board, Martz became aware of its potential environmental hazards."We''ve been on this farm since 1960, and the fuel tanks were put in place about then," says Martz. "We haven''t had any major leaks or spills, but it''s easy to see how something like that could happen. The tanks we''re putting in are much safer."
