The "Mac" Book
The book is a very small Atlas with places in it like Persia and Burma and Siam. There is also the area of French West Africa and the Belgian Congo. Turkey is listed twice as "Turkey in Asia" and later as "Turkey in Europe". "The Indian Empire" had 318 million or so people, (the book is quoting the 1921 census), and the US had 106 million in population. I can't find the copyright but I assume it was printed in the 1920's.
