urgent, other things equal, is the need of maintaining the proper working relations with these other industries, the greater is the industrial detriment suffered from any derangement of the accustomed working relations, and the greater is the industrial gain to be derived from a closer adaptation and a more facile method of readjustment in the event of a disturbance,—the greater is also the chance for an effectual disturbance of industry at the particular point. This mechanical concatenation of industrial processes makes for solidarity in the administration of any group of related industries, and more remotely it makes for solidarity in the management of the entire industrial traffic of the community.
A disturbance at any point, whereby any given branch of industry fails to do its share in the work of the system at large, immediately affects the neighbouring or related branches which come before or after it in the sequence, and is transmitted through their derangement to the remoter portions of the system. The disturbance is rarely confined to the single plant or the single line of production first affected, but spreads in some measure to the rest. A disturbance at any given point brings more or less derangement to the industrial process at large. So that any maladjustment of the system involves a larger waste than simply the disabling of one or two members in the complex industrial structure.
