.. Large hole

The four positions reminds of the moon phases.

It should be in the correct position for this day.

But you can't see the moon. You have to find that information somewhere else.

Look around in the camp.

There is a calendar on the wall next to the projector. Look at that. Nora will write the moon phases into the journal.

Try to find out what the current date is.

Nora keeps a journal, doesn't she.

Read the current date from the Log. ( It is November 7th, 1934. )

According to the calendar it is new moon today. Put the hole totally shut.
