The Late Thunderstorm

Abstract

THE thunderstorm which has just broken up the spell of hot weather for the past week presented some peculiar features as seen from this place. Commanding rather a wide horizon, I noticed about 8.30 last evening two distinct centres of disturbance, one S.W., the other N.E. It is impossible to estimate the distance by sound, as the thunder was inaudible. The electric spark, however, was visible enough, and I noticed that with one exception it went invariably from S. to W. in the one case, and from N. to E. in the other, and always horizontally from cloud to cloud. When I came out again at 10.15 I found the two centres had moved, so that one was slightly S. of E., and the other N. of W., but still directly opposite each other. It seems, too, that they had gone in the direction in which the electric spark had passed.
