Sawdust Stops Fire.

Recent experiments went to prove that sawdust is useful, as. a fire extinguisher. It was found to be very successful in quenching, fires in oil, and much superior to sand for fires in tanks of inflammable liquids. Experiments were conducted with tanks of burning lacquer,' though the same principles appear to apply lairgely to tanks of burning oil. The floating sawdust forms a blanket that shuts off the air from the flames, and sawdust itself catches fire only -slowly, and then does not bum with a flame. The sawdust blanket was completely successful in putting out the fires in these tests. It made no difference whether the sawdust was ; wet or dry. ' ,
