Upon returning, I'am still interested in the-report even-if it_is for 2 days.
If'you can find a substitute to fill in for you, it would be' helpful.
Please initial each day in the dato column.

Timing:
Each correspondent will be issued a quartz timer.
This will make all correspondences accurate on-timing.

Timing Periods:
Two 30 minute, or longer,-periods, A.M.
and P.M.
preferably.
If pressed for time, a 15 minute period is okay.
Try to do this randomly.

Record intervals on standard reporting form.
7.
After extended counts are completed, set monitor switches to COUNTS PER MINUTE and ALERT until next extended count period.
Upon retiring, monitors should be near a-bedroom window set for COUNTS PER MINUTE and ALERT.
When away from home, set monitor for extended count (see #6).
Alternatively, l
the monitor can be taken to the place of business furnishing the network with an additional station.
