Hi Tad,
In fact, this article appeared first in English in Answers magazine (London) in 1902.
«The future of the submarine. An instructive article by Jules Verne»
Answers. A Weekly journal of instruction, literature, interesting facts, amusing anecdotes, and jokes
vol. 15, nº 759, December 13, 1902, p. 79.
Before its publication in Popular Mechanics, it also appeared in several papers around the USA.
There's no known French MSS of this text and a publication existed in French in 1903 in a French journal titled Mon dimanche.
Best,
Ariel
