Novel Relay Demonstrated at British Fire Service College Novel techniques in water relaying were demonstrated at the Fire Service College, Wotton House, near Dorking. England last Fall during a series of five-day courses for chief fire officers and firemasters in the United Kingdom, at which problems arising from emergency fire-fighting were discussed. With four men, (two pump men, driver, mate), a line of 6-in. diameter canvas hose was laid by the prototype “emergency pattern” hose laying appliance carrying a mile of hose. After the hose had been joined to a pre-laid polythene plastic pipe line, water was pumped from one of the new 1,000-g.p.m. pumping appliances to discharge into a lightweight fibre glass tank. From this, three light portable pumps took water to supply 12 75-ft. hose lines terminating in light alloy branches having 3/4-in. nozzles. It was estimated that 900 g.p.m. of water were being passed along the quartermile…
