On these lines the agents set to work. Having formed themselves into a secret association called the “Union for the Emancipation of the Working Classes,” they gradually abandoned the narrow limits of coterie-propaganda, and prepared the way for agitation on a larger scale. Among the discontented workmen they distributed a large number of carefully written tracts, in which the material grievances were formulated, and the whole political system, with its police, gendarmes, Cossacks, and tax-gathers, was criticised in no friendly spirit, but without violent language. In introducing into the programme this political element, great caution had to be exercised, because the workmen did not yet perceive clearly any close connection between their grievances and the existing political institutions, and those of them who belonged to the older generation regarded the Tsar as the incarnation of disinterested benevolence. Bearing this in mind, the Union circulated a pamphlet for the enlightenment of the labouring population, in which the writer refrained from all reference to the Autocratic Power, and described simply the condition of the labouring classes, the heavy burdens they had to bear, the abuses of which they were the victims, and the inconsiderate way in which they were treated by their employers. This pamphlet was eagerly read, and from that moment whenever labour troubles arose the men applied to the Social Democratic agents to assist them in formulating their grievances.
