I found Soda Springs School on a 1911 survey map. It appears it was at the intersection of present Hwy 266 and Soda Springs Road (which is a section road three miles east of US Hwy 69). I don't know for sure where the spring(s) was located but it seems it must have been near the school. These are neighborhood schools that are only three or four miles apart so it seems unlikely the school would be named Soda Springs if the springs weren't at least within three miles or so. Just a guess. This is several miles north of Needham where I was guess it might be.
