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"
"The Department of Natural Resources (DNR) and other environmental agencies have determined that land spreading of contaminated soil is more acceptable," says Bob Broz, water quality specialist at the University of Missouri."Previously, farmers might have had to have soil from these sites transported to a hazardous waste incinerator. In most cases, they now can dig out petroleum-stained soil and spread it thinly across their fields, where natural biological activity breaks contaminants down," he says.
