Here is an illustration of West End from a book published in 1874.

The author describes the place:
"And by-and-bye we reached the West End, a collection of hotels of the usual light summer-resort pattern, with broad verandas all around, and the waves of the wide and blue Lake Pontchartrain lapping the thresholds. We had dinner on a ground-veranda over the water--the chief dish the renowned fish called the pompano, delicious as the less criminal forms of sin. Thousands of people come by rail and carriage to West End and to Spanish Fort every evening, and dine, listen to the bands, take strolls in the open air under the electric lights, go sailing on the lake, and entertain themselves in various and sundry other ways."

The book--Mark Twain, Life on the Mississippi.

I was amazed when I found that. Didn't realize that Clements wrote about the Lake as well as the River.
