Description is made briefly of a high-speed cinematographic technique newly developed by the author for recording the manner in which a fire stream disintegrates as it penetrates through air. The essential of the new method is that the motion of a stream fraction after its emergence from a nozzle-tip is followed up for a definite distance by means of a tilting mirror placed at about 45° to the axis of the high-speed camera lens. To give some indication of the merit of the new method, selected frames from a film taken of a 3/4", 60#/□" stream are reproduced.
