One of its most finished creations was the workshop for the production of the instruments of labour themselves, including especially the complicated mechanical apparatus then already employed. A machine-factory, says Ure, "displayed the division of labour in manifold gradations the file, the drill, the lathe, having each its different workman in the order of skill." (P. 21.) This workshop, the product of the division of labour in manufacture, produced in its turn machines. It is they that sweep away the handicraftsman's work as the regulating principle of social production. Thus, on the one hand, the technical reason for the life-long annexation of the workman to a detail function is removed. On the other hand, the fetters that this same principle laid on the dominion of capital, fall away.
