You're welcome. I tried to be consistent with the HTML formatting of the entire series. I corrected lots of OCR errors (hopefully I got them all) and added em-dashes where appropriate. Nothing fancy, just the basics. If anyone finds more errors, let me know and I'll correct them.
Although some may classify these stories as juvenile adventures, I found them quite enjoyable. If I had read them when I was a kid, I don't think I would have gotten as much out of them. Burroughs has a way of telling a very good story.
