“From letter to Sigfrid Meyer (in New York), Hanover, April 30, 1867. Dear Friend: So far as the International Working Men’s Association is concerned, it has become a power in England, France, Switzerland, and Belgium. Do organize in America as many branches as possible. Contribution per member is one penny (about one silver groschen) yearly. Still, every community donates what it can. The Congress this year will be in Lausanne, on September 3. Each community may send one representative. Write me about this matter, about what has happened to you in America, and about the general situation. If you remain silent, I will consider it proof that you have non yet forgiven me. With warmest regards. Yours, Karl Marx” [Karl Marx, On the First International, a cura di Saul K. Padover, 1972]
