All students of meteorology are familiar with the atmospheric condi- 
tions which prevail when tornadoes occur as well as with the usual freak- 
ish behavior of storms of this type. The writer has not discussed these 
points for this reason, nor does he wish to make a comparative study of 
this storm in this report. He has aimed only to state as many of the facts 
concerning this one meteorological event as he was able to ascertain in 
the brief time at his disposal, trusting that they may add a smal! part 
to the great fund of information already recorded concerning these small 
but violent atmospheric disturbances.
