Why is it necessary to begin trading with other farms, and how do the animals react to this new policy?
In chapter 6, Napoleon gathers the animals and explains that he will implement a new policy by beginning to trade with humans from neighboring farms. Napoleon assures the animals that he is only trading with humans for commercial purposes since there are many tools and materials needed to construct the windmill that the animals cannot procure on the farm. After listening to Napoleon's new policy, four pigs begin to protest but are abruptly silenced by a tremendous growling from the dogs. Napoleon also announces that they will conduct business using an intermediary named Mr. Whymper. Following the meeting, the animals feel uneasy about engaging in trade with humans and vaguely remember there being a tenet of Animalism that prohibited trade and contact with humans. However, Squealer eases their minds by assuring them that a resolution against engaging in trade and using money had never been passed or even suggested.
It is necessary to begin trading with other farms even though there is a food shortage to raise money to build the windmill. The animals are also informed that if it is necessary they will also begin to sell the hen's eggs in Willingdon.
The animals are very uneasy with the announcement because they remember that they had passed a resolution to not trade with humans at the first meeting after Jones was expelled. The dogs growls and the bleating of the sheep quickly bring to an end any criticism, and Snowball goes on to tell them they must have been mistaken because there was nothing of the sort said at that meeting.
