What holds good for Spanish holds good for even other so called natural language, including English, and more with English than any other on account of its barbarous spelling and pronunciation.
None of these objections, neither structural nor national, apply to Esperanto, which is entirely neutral and ideally simple.
(3) The U.E.A. (Universala Esperanto Asocio) has its central office at 10 Rue de la Bourse, Geneva, Switzerland. Yearly dues 50 cents for private members, $2.50 for business firms. These contributions entitle the members to use the machinery of the association for the acquisition of information--free of cost, except postage--on any subject whatever (except confidential matters), the only condition being that the request be written in Esperanto. A sufficient amount of Esperanto for this purpose can be acquired by anyone in a few days, or even in a few hours. It is not even necessary to have a teacher, the textbooks being very easy to master. In America, if local booksellers do not yet stock Esperanto literature, the would-be student may apply to Peter Reilly, Esperanto bookseller, 133 North Thirteenth Street, Philadelphia, Pa.
A growing number of Esperantists all over the world are using the services of the U.E.A., not only in correspondence, but actually traveling through many countries for pleasure or profit by means of Esperanto alone, and finding everywhere helpful hints and congenial surroundings in the local Esperanto groups.
In addition to the U.E.A. there is an international Esperanto society for the propaganda of the language; this has its world center at 51 Rue de Clichy, Paris, France, and powerful national societies in France (240 branches), in England (118 branches), in Germany (over 250 branches), etc.
(4) I should, however, add, in justice to the American people, that wherever Esperanto has been brought to their notice by press or platform it has been well received. I have myself lectured to large and sympathetic audiences in Chautauqua, Buffalo, New York, Philadelphia, Pittsburgh, and Washington. Public schools, high schools, and universities have frequently opened their doors to Esperanto, and in my own case the University of Pennsylvania and the University of Columbia have shown their open-mindedness to the extent of engaging a paid lecturer for a prolonged course.
