William W. Mann, Esperanto Self-Taught with Phonetic Pronunciation
“ Esperanto is not merely a language for tourists, but already possesses a rich literature of considerable extent, the beginnings of that "Weltlitteratur" foreseen by Goethe; it has a press of its own representing every country of importance in the world, and is constantly being made use of for professional purposes by doctors, scientists, teachers, lawyers, soldiers, sailors, merchants, etc., in every quarter of the globe. It is undoubtedly destined, ere many years have passed, to become a very important factor in the progress of the world. ”
