"_After the work was well under way about two hundred new clerks were put into one room and scattered through the force already at work. They had no experience with schedules, knew nothing of the symbols, had never seen the machines. They saw those around them working easily and rapidly, and in_ THREE DAYS SEVERAL OF THEM HAD DONE FIVE HUNDRED, IN A WEEK NEARLY EVERY ONE, _while the general average was rising_. There was no longer any question of nervous strain, and one of these temporary clerks the day before she left beat the record by doing 2,230. I think the influence of the mental attitude quite as remarkable in the matter of their doing the work easily as in that of doing it rapidly. During the first month many were actually sick from overwork when doing seven hundred, while after that time the idea that the work was unusually trying was never referred to. Another significant fact is that after the posting of the daily record was abolished there was no falling off in the daily average, as had been anticipated, while complaints of overwork necessarily ceased." It is thus demonstrated that an unskilled clerk, with an environment proving the possibility of a task and suggesting its easy accomplishment, can in _three days_ succeed in doing what a skilled clerk, with a preliminary acquaintance of five weeks with the symbols to be used, could do only after _two weeks'_ practice; and this because the latter, doubtless not a whit inferior in ability, had been led to regard his task as difficult.
