FIG. 1 IS A COMPILATION OF ALMOST ALL THE DATA. EXCEPT FOR THE EXTRA B RIGHTNESS AND RETARDATION OF A PART OF THE SPHERE NEAR THE BOTTOM, A N UMBER OF BLISTERS, AND SEVERAL SPIKES THAT SHOT RADIALLY AHEAD OF THE BALL BELOW THE EQUATOR, THE EXPANSION OF THE BALL OF FIRE BEFORE STRI KING THE GROUND WAS ALMOST SYMMETRIC, FOLLOWING THE RELATIONSHIP RADIU S TIMES TIME (TO THE 2/5), WHERE R IS THE RADIUS AND T IS THE TIME IN SECONDS. CONTACT WITH THE GROUND WAS MADE AT 0.65 PLUS OR MINUS 0.05 MILLISECONDS, THEREAFTER, THE BALL BECAME RAPIDLY SMOOTHER. FROM 1.5 TO 32 MILLISECONDS THE TIME DEPENDENCE OF THE RADIUS FOLLOWED CLOSELY THE RELATIONSHIP. RADIUS TIMES THE QUANTITY, TIME + 4 TIMES 10 TO THE MINUS FOUR (QUANTITY TAKEN TO THE 2/5 POWER). AT 3 MILLISECONDS THERE APPEARED AT THE BOTTOM OF THE BALL AN IRREGULAR LINE OF DEMARCATION, BELOW WHICH THE SURFACE WAS APPRECIABLY BRIGHTER THAN ABOVE, THIS LIN E ROSE LIKE THE TOP OF A CURTAIN UNTIL IF DISAPPEARED NEAR THE TOP OF THE BALL AT ABOUT 11 MILLISECONDS. SHORTHLY AFTER THE SPIKES STRUCK TH E GROUND THERE APPEARED ON THE GROUND AHEAD OF THE SHOCK FRONT A WIDE SKIRT OF LUMPY MATTER, AND WITHIN AND ABOVE THE SKIRT A SMOOTH BELT ( INTERPRETED AS THE MACH WAVE), ORIGINALLY BRIGHTER THAN THE MAIN FRONT BUT RAPIDLY GROWING DIMMER. TWO SUCCESSIVE VISIBLE FRONTS DROPPED BEH IND THE WELL-DEFINED SHOCK FRONT. THE BRIGHTER BUT LESS SHARPLY LIMITE D BALL OF FIRE FELL BEHIND IT AT ABOUT 0.016 SECONS. AT ABOUT 0.032 SE CONDS THERE APPEARED IMMEDIATELY BEHIND THE SHOCK FRONT A DARK FRONT O F ABSORBING MATTER, WHICH TRAVELED SLOWLY OUT UNTIL IT BECAME INVISIBL E AT 0.85 SECONDS. THE SHOCK FRONT ITSELF BECAME INVISIBLE AT ABOUT 0. 10 SECONDS, BUT WAS FOLLOWED UNTIL 0.39 SECONDS, FIRST BY ITS LIGHT-RE FRACTING PROPERTY AND LATER BY THE IMPULSE IT IMPARTED TO A BALOON CAB LE. THE MASS MOTION OF THE AIR COULD BE DETERMINED FROM A STUDY OF THE MOTION OF THE VAPOR OF THE BALLOON CABLE. THE BALL OF FIRE GREW EVER MORE SLOWLY TO A RADIUS OF ABOUT 300 METERS, UNTIL THE DUST CLOUD GRO WING OUT OF THE SKIRT ALMOST ENVELOPED IT. THE TOP OF THE BALL STARTED TO RISE AGAIN AT 2 SECONDS. AT 3.5 SECONDS A MINIMUM HORIZONTAL DIAME TER, OR NECK, APPEARED ONE-THIRD OF THE WAY UP THE SKIRT, AND THE PORT ION OF THE SKIRT ABOVE THE NECK FORMED A VORTEX RING. THE NECK NARROWE D, AND/THE RING AND THE FAST-GROWING PILE OF MATTER ABOVE IT ROSE AS A NEW CLOUD OF SMOKE, CARRYING A CONVECTION STEM OF DUST UP BEHIND IT. A BOUNDARY WITHIN THE CLOUD, BETWEEN THE RING AND THE UPPER PART, PERSI STED FOR AT LEAST 22 SECONDS. THE STEM APPEARED TWISTED LIKE A LEFT-HA NDED SCREW. THE CLOUD OF SMOKE, SURROUNDED BY A FAINT PURPLE HAZE, ROS E WITH ITS TOP TRAVELING AT 57 METERS PER SECOND, AT LEAST UNTIL THE T OP REACHED 1.5 KILOMETERS. THE LATER HISTORY OF THE CLOUD WAS NOT QUAN TITATIVELY RECORDED.
