“The Socialist Party of Great Britain, a young organisation and an offshoot from the  Social Democratic Party, is spreading about London and challenging the older organisations in such districts as Battersea and Tottenham. The members are Marxians and revolutionaries, preaching the Class War. The catechumens of the party are put through a rigid course of training in the principles of their creed, which they must be prepared to defend at the risk of their liberty. What is most remarkable and disquieting about this dangerous organisation is the fact that the members are unquestionably higher-grade working-men of great intelligence, respectability, and energy. They are, as a whole, the best informed Socialists in the country, and would make incomparable soldiers, or desperate barricadists. As revolutionaries they deserve no mercy : as men they command respect.”
