The five or six years following the collapse of the great lock-out of 1852, though constituting a period of quiet progress in particular societies, are for the historian of the general Trade Union Movement, almost a blank. The severe commercial depression of 1846-49 was succeeded by seven years of steadily expanding trade, which furnished no occasion for general reduction of wages. The reaction against the ambitious projects of the Trade Union of 1834 continued to discourage even federal action;[366] whilst the complete failure of the struggle of the engineers, followed as it was in 1853 by the disastrous strike of the Preston cotton-spinners for a ten per cent advance, by an equally unsuccessful struggle of the Kidderminster carpet-weavers, and by a fierce and futile conflict by the Dowlais ironworkers,[367] increased the disinclination of the Unions to aggressive trade action on a large scale. The disrepute into which strikes had fallen was intensified by the spread among the more thoughtful working men of the principles of Industrial Co-operation. This new development of Owen’s teaching took two forms, both, it need hardly be said, differing fundamentally from the Owenism of 1834. In Lancashire the success of the “Rochdale Pioneers,” established in 1844, had led to the rapid extension of the Co-operative Store, the association of consumers for the supply of their own wants. To some extent the stalwart leaders of the Lancashire and Yorkshire working men were diverted from the organisation of trade combinations to the establishment of co-operative shops and corn-mills. Meanwhile the “Christian Socialists” of London had caught up the idea of Buchez and the Parisian projects of 1848, and were advocating with an almost apostolic fervour the formation of associations of producers, in which groups of working men were to become their own employers.[368]
