cent. The increase per day from June on day work, to July on piece work, the hours each month being 1012 per day, was 37 per cent. This increase was due to the introduction of piece work. The increase per day from July to August (the length of working days in July being 1012 hours, and in August 912 hours, both months piece work) was 33 per cent.
The increase from August to September (the length of working day in August being 912 hours, and in September 812 hours) was 0.08 per cent. This means that the girls did practically the same amount of work per day in September, in 812 hours, that they did in August in 912 hours.
To summarize: the same ten girls did on an average each day in September, on piece work, when only working 85 hours per day, 2.42 times as much, or nearly two and one-half times as much, in a day (not per hour, the increase per hour was of course much greater) as they had done when working on day work m March with a working day of 1012 hours. They earned $6.50 to $9.00 per week on piece work, while they had only earned $3.50 to $4.50 on day work. The accuracy of inspection under piece work was one-third greater than under day work.
The time study for this work was done by my friend, Sanford E. Thompson, C. E., who also had the actual management of the girls throughout the period of transition. At this time Mr. H. L. Gantt was general superintendent of the company, and the work of systematizing was under the general direction of the writer.
It is, of course, evident that the nature of the
