The problem was in thiscondition when it was taken over by the Mechanical Researchand Development Section. At this time the whole problem wasgone over carefully to see that it was being attacked in theright angle. A conference with Major Matthews and of the Trench Warfare Division, Ordnance Departmentdeveloped that it-was not essential that a flaming liquid inthe ordinary sense should be used. A large flame- of gas orliquid preferably, from 5 to 10 feet long and 3 feet in diam-eter would be desirable. Simplification and reduction inweight were very essential factors. The final device complie-ted by the Justrite Company was successfully demonstrated -108-. oo d3 o t—! pq s o Pi o M Eh a .3392 before mempers of the Ordnane-e Department and the PyrotechnicSection. There was also present IVEajor Holland-, who hadhad considerahle experience abroad training with the jSnglishtroopg in Flanders^ He stated that the weight of a device onthe end of the gxm would offer no practical abjection orinterference with the use of the bayonet if it could be madeto function successfully. He favored the proposal to useseparate shots or cartridges rather than a single flash whoseduration could be controlled by the operator. Results ofthis demonstration were eiicouraging and work was continuedactively to attempt the use of compressed liquid gas both asa pilot flame and a means to project the flaming of compressed gas and flaming liquid were also con-sidered.
