This manual should bring back some memories.
Of course, many of the rules and regulations
no longer apply to us in this modern age.
However, some advice is still very good
and may well be applied today.  For instance:

pg 29-30   - how to add inches to your height
pg 30      - dealing with strong and offensive body odor and bad breath
pg 35      - on using the elbow as a fulcrum for conveying food to the mouth
pg 36      - how to use a napkin
pg 36      - zigzag eating
pg 36      - using the knife and fork as spear and trident
pg 37      - "one ought not to look away from the person to whom
              he is passing a dish as he may not be there"
pg 38      - how to eat soup
pg 39      - how to eat a baked potato

(Now be sure to listen to the "Biblical Food Parody" below).

The above eating rules bring to my mind the following
"Biblical Food Parody".  The first is a parent talking
to his children.  The second is a discussion with the
author of the parody.  Listen and enjoy.
