 (luring a distanl shuiii (in June 30, 1918. The display lasted for 

 scN'cral hinirs and ihiumh ilic lit^htninj; was brilliant over a full 

 (|uaii('i- dl' ilif lii)ii/(in I'liini W'.S.W . to \.\,\\ ., ihc center seemed 

 to remain slightly north of west of the ohscrxalion point which was 

 twehe miles north of \'ictorville. 



The Hashes were almost incessant and at last after a series of un- 

 usually brilliant ones the camera was brou<j;ht out and set with open 

 shutter pointing as nearly as possible toward the heart of the storm. 

 It was a busy few minutes closing the shutter and winding the film 

 and one can not be certain that the double flashes shown were simul- 

 taneous but at least the interval must be measured in fractions of 

 seconds for the effort was made to close the shutter with the flash. 



The small trees shown in the various pictures indicate how little 

 the center of the storm moved, — at least in a northerly or southerly 

 direction. 



Several times before the camera was brought out and during the 

 intervals of resetting, flashes were seen having a complete loop in 

 their line and it was with deep regret that the camera was put away 

 with all the films exposed and no record of the looped lightning. 

 However when the roll was developed, the plate marked Xo. 1 showed 

 a looped flash which had been caught by the camera and not by the 

 eye. 



Of all the thunder storms and pictures of lightning which the 

 writer has seen this storm was the first to show the loops and the 

 record of the cajnera confirms the impression of the eye. The great 

 regret is that though several such flashes were witnessed only one 

 w^as recorded. 



The remaining pictures while not unique are at least accurate 

 records of a most remarkable electrical display. Plates Nos. 2 and 3 

 show in the horizontal flashes lines closely approximating loops 

 formed by the branching and uniting of the main flash but an ex- 

 amination of Plate Xo. 1 shows the loop in the direct line of discharge 

 and as much a part of the flash as a loop in a rope.
