In future Party Committees must see to it that street cells are constructed so that in their day to day work they should help the Party Committee to strengthen its connection with the workers in big enterprises, strengthen the work of factory cells and so on. This should be the fundamental practical rule for the organization and work of street cells. At the same time it must be firmly borne in mind that along with the development of the class struggle Party Committees must not fail to carry out changes in the composition and structure of the street cells which may become necessary, make a re-grouping of the forces of the members of street cells, in order at a given moment to have a concentration of forces on the most important sectors of the front of the class struggle. For example, if some unrest should arise in a textile factory, the Party Committee must at once consider the possibility of developing that unrest into a strike inside the factory. But a strike can only be organized provided good preparatory work has been carried out. Who must carry it out? In the first place Party members and sympathizers working in the textile factory, but on the other hand, the Party Committee must organize the maximum assistance for these comrades, drawing on Party members working in other factories, and also members of street cells. There can be all kinds of combinations here. For example, it might be advisable and practicable that a Party member working as a fitter in a metal factory, a member of the factory cell of the metal factory should apply for a job in the textile factory where a fitter may be needed. Everything must be done in order by such means to strengthen the cell of the textile factory from within. Further, let us suppose that near the textile factory a street cell is working and that in this street cell there are, let us say, five more or less weak comrades living in the district. It is essential to strengthen this street cell by including in it a number of other comrades who live nearby, or even at the other end of the town, in order with the help of this street cell to strengthen the agitation among the workers of the textile factory on their way to and from work, to strengthen through this street cell the distribution among the workers of a textile factory paper, leaflets, and other literature which may be issued by the Party with the aim of preparing and organizing a strike, in this textile factory. Let us suppose that after the strike is finished a movement begins in another factory; the Party Committee must at once regroup its forces in order to concentrate them again on another fighting sector of the Party work. And so all the time. It is impossible to regard the Party structure or any local organization as something unshakably firm and not liable
