RIGA, LATVIA—Lenine's personality and the faith that most Russian peasants and workingmen have in him, despite their dissatisfaction with conditions under which they are forced to live, is perhaps the one big factor that holds the Bolshevik regime in power, says Captain M. C. Cooper, of Jacksonville, Fla., who escaped from a prison camp near Moscow. Coptain Cooper was flying for the Polish dry when made prisoner in July, 1920. "Lenin is still the most popular man in Russia," said Captain Cooper, "much more so than Trotzky. I found that the majority of peasants and workingmen, even those in prison, believed in him. They are terrorized by the 'Tcheka,' or Counter Revolutionary committee, which really is running things, in Russia. But I believe that if the 'Tcheka' were abolished practically everybody would be for Lenin." This, said Captain Cooper, is not hard to understand, for Lenin's pictures have been distributed everywhere. Travelers in Russia will see two of his pictures for every one of Trotzky.
