We are now ready for the stop watch, which, to save clerical work,
should be provided with a decimal dial similar to that shown in Fig. 4.
The method of using this and recording the times depends upon the
character of the time observations. In all cases, however, the stop
watch times are recorded in the columns headed "Time" at the top of the
right-hand half of the note sheet. These columns are the only place on
the face of the sheet where stop watch readings are to be entered. If
more space is required for these times, they should be entered on the
back of the sheet. The rest of the figures (except those on the
left-hand side of the note sheet, which may be taken from an ordinary
timepiece) are the results of calculation, and may be made in the office
by any clerk.

[Transcriber's note -- omitted]
As has been stated, the method of recording the stop watch observations
depends upon the work which is being observed. If the operation consists
of the same element repeated over and over, the time of each may be set
down separately; or, if the element is very small, the total time of,
say, ten may be entered as a fraction, with the time for all ten
observations as the numerator, and the number of observations for the
denominator.
In the illustration given on the note sheet, Fig. 2, the operation
consists of a series of elements.
