Industry \In"dus*try\, n.; pl. Industries. [L. industria, cf.
   industrius diligent; of uncertain origin: cf. F. industrie.]
   [1913 Webster]
   1. Habitual diligence in any employment or pursuit, either
      bodily or mental; steady attention to business; assiduity;
      -- opposed to sloth and idleness; as, industry pays
      debts, while idleness or despair will increase them.
      [1913 Webster]

            We are more industrious than our forefathers,
            because in the present times the funds destined for
            the maintenance of industry are much greater in
            proportion to those which are likely to be employed
            in the maintenance of idleness, than they were two
            or three centuries ago.               --A. Smith.
      [1913 Webster]
