Query: Too much filler that has little to do with the subject of the book

Disappointing. I was hoping for more of a look into the science of timekeeping, something as detailed and interesting as Dava Sobel's "Longitude." This book mostly contains a whole lot of rambling about Victorian attitudes and modes. Sandford Fleming himself was still enigmatic at the end of the book. I just didn't find enough here to hold my interest. Not recommended.
