Randall,
I found this article in the 1909 Popular Electricity magazine, "Playing Base Ball at Night". The article is talking about lighting a ball field in Cincinnati. While this article is talking about electricity and not gas, I find it quite contradictory to everything thing else I have been reading. Everything I have read (so far) talks about "electric lighting" for ball fields at a much later date?
Anyway I thought you might be interested in the article and that you might be able to Identify the players and field???
