In the latter, owing to there being no definite standard, it is quite possible that the prices may be raised too high for competitive efficiency, or depressed to too low a point to recoup the workmen for the extra exertion and initiative induced by the very nature of piecework. In such work as that of rivetters, iron fitters, and platers and...
