NOTE.-For guns, to compute the deviation in yards with reference to line joining tug and target multiply the average of the mils observed by the three observers by rob of the length of the towline in yards. Example.-Suppose the observers to have reported the splash 100, 105, and 110 mils, respectively, beyond the target, and suppose the towline to be 290 yards long. The average of the observations is 105 mils, 105 x 30.45 yards.

This form will be used by the officer in
charge of range observers for recording devia-
tions in mils observed with range rake and
the computed deviations in yards with respect
and target.
to the proper target and the line joining gun

The officer in charge of observers will date,
sign, and deliver his report, accompanied by his
computations of deviations in yards, to the fire
commander as soon as practicable after the
practice. Any one of Form 823 delivered will
contain data relating to one battery only.

This report will be filed with the retained
copy of Form 819 to which it relates for one
in which the firing took place.
year after the completion of the practice year
