The animals had their breakfast, and then Snowball and Napoleon called them together again. "Comrades," said Snowball, "it is half past six and we have a long day
before us. Today we begin the hay harvest (сенокос). But there is another matter that must be done first." The pigs now revealed that during the past theree months
they had taught themselves to read and write from an old spelling book which had belonged to Mr Jones's children. They explained that by their studies of the past
three months the pigs had succeeded in reducing the principles of Animalism to seven commandments. These seven commandments would now be written on the
wall; they would form an unalterable law by which all the animals on Animal Farm must live for ever after. With some difficulty (for it is not easy for a pig to balance
himself on a ladder) Snowball climbed up and set to work. The commandments were written on the wall in great white letters that could be read thirty yards away.
They ran thus:
THE SEVEN COMMANDMENTS
1. WHATEVER GOES UPON TWO LEGS IS AN ENEMY.
2. WHATEVER GOES UPON FOUR LEGS, OR HAS WINGS, IS A FRIEND.
3. NO ANIMAL SHALL WEAR CLOTHES.
4. NO ANIMAL SHALL SLEEP IN A BED.
5. NO ANIMAL SHALL DRINK ALCOHOL.
6. NO ANIMAL SHALL KILL ANY OTHER ANIMAL.
7. ALL ANIMALS ARE EQUAL.
Snowball read it aloud for the benefit of the others. All the animals nodded (кивали) in complete agreement, and the cleverer ones at once began to learn the
commandments by heart.
It was soon found that many animals such as the sheep, hens and ducks were unable to learn the Sevev Commandments by heart. After much thought
Snowball declared that the Seven Commandments could be reduced to a single saying, namely:"Four legs good, two legs bad." This, he said. contained the
essential principle of Animalism.
