How a Salesman Lost an Order An officer of the Topeka, Kan., Fire Department was persuaded by a salesman to permit a demonstration of a new type fire extinguisher. Five gallons of gasoline were poured on the ground near the station and then ignited. Nothing happened. When the flames started to scorch the doors of the station, the flames were extinguished with the department’s equipment. Although this proved an interesting few moments, no order followed.
