This was written in a Victorian style in the early 1900s I think and aside from being replete with praise for German culture, is unabashed about printing long-held stereotypes. It's very easy to read, concise, and focused on strong personalities from history. The history more or less follows that of German history museums I've visited.
There is a page or two pointing out that very large parts of Europe and the UK are essentially Germanic tribes. That includes the French and English, who should apply to Mary Parmele's ancestors to lodge their complaints. Wouldn't it be tragicomedy if European history is pockmarked with pointless quarrels between second cousins?
