The close relation of thre>herexpl()si(jns to the general stutly of grain-dust explosions led to the inauguration ofa special inestigation of this allied problemin the northwestern tiekl during the 11)15season. As a result of this study one hun-dred and sixty-six tires were inesligaledand reported. The investigation indicated that thewheat crop c o n t a i 11 e d alarge ])ercentage of smut (atorm of er- line, dry dust)and that tlie explosions andlires in man- cases were dueto the formation of an explo-sie n)ixluri oi snmt-dust andfc^ J air and ihe igniliiin of this niixlure by sialic electricil>(hiring the lhre>hing opera-lions.

It was estimated that a million gallons of water werepoured on the fire without subduing it. The smut-dust theory is advanced as the cause of it grain were destroyed. The grain loss dueto the fires investigated reached about$50, 000. The experimental work carried on duringthe investigations proved conclusively that, under favorable atmospheric conditions, static electricity is present on ail types ofmachines. It appears that the largestdischarges of static electricity were ob-tained from the steel machines. The fires and explosions occurred, as arule, when fall wheat was being threshed, and very rarely occurred dur-ing the threshing of springwheat. The discharge fromthe machines, while smuttywheat was being threshed, was more noticeable thanwhen clean wheat wasgoing through the process.l-all wheat, as a rule, con-tained much more smut thanspring wheat.
