Were there six people of your calibre in Germany, the resistance of the philistine mass and the conspiration de silence  of the experts and newspaper crowd would have been so far broken down that at least some serious discussion would have begun. Mais il faut attendre!  In these words lies the whole secret of Russian policy. I am enclosing a letter (please return it) from a German-Russian worker (a tanner).  Engels remarks, quite rightly, that the autodidactic philosophy pursued by workers themselves has made great progress in the case of this tanner in comparison with the cobbler Jakob B hm;  also that only German workers are capable of such cerebral work. Borkheim  asked me yesterday who had written the article in the Zukunft (he is a subscriber). It must come from one of our people, since you had sent him a copy of it. I said I did not know. Nota bene! One should not put all one s cards on the table. My most cordial thanks to your dear wife for the trouble she took in copying the letter. You should not exploit her so much for surplus labour . Bucher,  as, if I am not mistaken, I have already told you, has himself asked me to be the economic correspondent of the Royal Prussian Staatszeitung. So you see that if I wanted to make use of such sources, I could do so without the mediation of a third person. My illness is the old one nothing dangerous, but troublesome. With best greetings to your dear wife and Fr nzchen.
