and the working conditions are such that the managers furnish the
worker with inducements to conform to the standard conditions
happily.

WORKER'S RETENTIVE POWER INCREASED.--We note in the second
place, the increased retentive power of anyone who is working with
standards. There is great difference between different people of the
same degree of intelligence as to their ability to memorize certain
things, especially such as sequences of the elements of a process.
This lack of retentive power is illustrated particularly well in the
cases often found where the student has difficulty in learning to
spell. It is here that the standard instruction card comes into play
to good effect. Its great detail remedies the defect in memorizing
of certain otherwise brilliant workers, and its standard form and
repetition of standard phrases aid the retentive power of the man
who has a good memory.

STANDARD ELEMENTS SERVE AS MEMORY DRILLS.--This use of
standardized elements makes the time elapsing between repetitions
shorter, for, while it may be a long time before the worker again
encounters the identical work or method, still, the fact that
elements are standard means that he will have occasion to repeat
elements frequently, and that his memory will each time be further
drilled by these repetitions.

GANG INSTRUCTION CARD AN AID TO MEMORY.--The gang instruction
card has been used with good effect at the beginning of unfamiliar
repetitive cycles of work to train the memory of whole gangs of men
at once, and to cut down the elapsed time from the time when one
man's operation is sufficiently completed to permit the next man to
commence his. It has been found, in the case of setting timbers in
mill construction for example, that to have one man call out the
next act in the sequence as fast as the preceding one is finished,
until all have committed the sequence to memory, will materially
decrease the time necessary for the entire sequence of elements in a
cycle of work.

INDIVIDUAL INSTRUCTION CARD AN INANIMATE MEMORY.--The
instruction card supplies a most accurate memory in inanimate form,
that neither blurs nor distorts with age.

The ranter against this standard memory is no more sensible than
a man who would advocate the worker's forgetting the result of his
best experience, that his mind might be periodically exercised by
rediscovering the method of least waste anew with each problem.
