to the truck as the "Marguerite" to differentiate it from other equipment and the nickname stuck. The name was later painted onto the side of the unit.(16) TECHNOLOGY AND OPERATIONS Techniques and tactics for extinguishing uncontrolled structure fires and protecting the contents thereof would evolve over time. In America's Colonial Period, when an uncontrolled structure fire almost guaranteed that the building would burn to the ground due to a lack of adequate firefighting capability, volunteer organizations of concerned citizens rescued victims and carried out furniture, specifically the costly bed first,(17) and any other property that could be reached and removed as the only option open to them. By 1800, volunteer fire brigades were common in most cities, the first of which was formed in Philadelphia by Benjamin Franklin in 1736. Most of these were ineffectual bucket brigades or used hand-powered engines of little capacity although somewhat better than buckets alone.(18) In 1852, Alexander Bonner Latta, a railroad locomotive builder in Cincinnati, in cooperation with Abel Shawk and Miles Greenwood, a local foundry operator and future Chief of the new Cincinnati Fire Department, created the first successful steam-powered piston-pump fire engine.(19) This advance in technology would rule firefighting until the early 20th Century when fire trucks with gasoline engines replaced pumpers powered by steam and drawn by horses. By mid-century, centrifugal pumps would replace piston pumps on all fire fighting vehicles.(4) Advances in salvage operations followed advances in fire fighting. In Cincinnati in 1836, Mathew Carey, known locally as "Old Mat", is credited with innovating the use of wet mats, wet carpets, and wet blankets hung on adjacent buildings as a form of protection from taking fire from the burning theater next door. Fifty years later, this innovation would become the centerpiece of Salvage Corps operations. Made of "duck", a course woven cotton clothe graded by weight from 1, the densest, to 12, the lightest, as set by the Federal Bureau of Standards, these 12 by 18 foot covers, like tarpaulins, were used in a variety of ways depending upon their Salvage Corps classification - Class A's were new, Class B's were older covers and contained tears or holes that had been patched at some prior time, Class C's were older still, had been patched many times and were only used to cover broken windows. When Class C's were no longer serviceable, they were cut up and used as patches. The
