I was in a position to give more than verbal tidings of the new tendency. We had succeeded, despite all official scrutiny, in smuggling various prohibited writings into the prison, and among them the first publication of our group, Plehànov’s _Socialism and the Political Struggle_. For a long time no forbidden literature had penetrated to Kara; the excitement was great, and the new material for thought was seized on with avidity. I was very anxious to discover Sundelèvitch’s attitude towards this problem, for in the old days, when we were nearly all Terrorists, he was considered as more or less of a Social Democrat—at any rate, he had been known to approve of the German development on those lines, so far as that country was concerned. We had been acquainted in 1878, when he had in charge the transport of forbidden literature for the _Zemlyà i Vòlya_ (Land and Liberty) group; and he had made use of his special experience in such illegal traffic to get Stefanòvitch and myself safely across the frontier after our flight from Kiëv prison. At that time we had had many hot discussions with Sundelèvitch over the methods of conducting our struggle in Russia; for I was then a decided opponent of the Social Democrats, and as a Terrorist and “Naròdnik” (_i.e._ member of the party whose object it was to organise revolts among the peasants) held the peaceful tactics of German Socialists to be utterly ineffectual—naturally, therefore, I would have all the more scouted the idea of introducing them into Russia. Sundelèvitch, on the contrary, did not believe in “the People,” and thought agitation among the Russian working-classes quite futile. In his opinion the first thing to do was to fight for political freedom; and then, as soon as that was obtained, to resort to the constitutional methods of the German Social-Democratic party. Consequently, he did not join the terrorist party till it began its political activity in 1878; and he was one of the first to enunciate the idea that its methods were only temporarily adopted because they offered the sole possible means in Russia of overthrowing the existing political order. He was one of the most energetic in organising terrorist conspiracies, and the party owed much to his help in carrying through their active work; he was invaluable in striking out the most effective and practical suggestions. He was arrested quite by chance in a public library in Petersburg during the autumn of 1879, and was prosecuted in the “Case of the Sixteen,” when Kviatkòvsky and Pressnyàkov were sentenced to death, and he himself to lifelong penal servitude.
