Moreover, if the organisational work of the trade-unions is for the most part of a very difficult and troublesome kind, it is, with the exception of a few cases and some districts, not merely because on the whole, the soil has not been prepared by the social democratic plough, but also because the trade-union seed itself, and the sower as well, must also be "red," social democratic before the harvest can prosper.
