Editorial comment on this plate:

We take pleasure in presenting our readers, this week, with a page of lightning photographs from negatives by W. N. Jennings, of Philadelphia. Mr. Jennings has long made a study of this interesting branch of photographic work, and has probably obtained more remarkable results than any other photographer in this country. In the interesting article which follows, he tells us how the negatives were obtained, as well as much of value about the lightning itself.
The reproductions were made by F. Gutekunst, of Philadelphia, and are “excellent” in Mr. Jennings’ opinion. “The upper right-hand photograph,” he writes, ” represents a bunch of ‘knotty’ sparks taken to identify ‘artificial’ with ‘natural’ discharges.”
The other photographs show three different kinds of lightning flashes, and all are highly interesting and instructive.
