“A few days ago the cheery little hunchback Wedde turned up – only to disappear again to Germany shortly after. He had a pressing commission from Geib to enlist you and me for the Zukunft. I made no secret to him whatever of our intentions of abstaining, to his great sorrow, and of our reasons for this, and explained to him at the same time that when our time allows or circumstances demand that we should again come forward as propagandists, we, as internationalists, are in no wise bound or pledged to attach ourselves to Germany, the beloved Fatherland.”
