In this excerpt, only one character, Squealer, is shown to be speaking for himself through dialogue. Why do you think Orwell chose to include that
character's speech while only summarizing the main points of Napoleon's
and Snowball's speeches?

Every tyrant has his sycophants, and Napoleon has one in Squealer, a clever pig who (as the animals say) "could turn black into white." Throughout the novel, he serves as Napoleon's mouthpiece and Minister of Propaganda. Every time an act of Napoleon's is questioned by the other animals — regardless of how selfish or severe it may seem — Squealer is able to convince the animals that Napoleon is only acting in their best interests and that Napoleon himself has made great sacrifices for Animal Farm. For example, after Squealer is questioned about Napoleon's stealing the milk and windfallen apples, he explains that Napoleon and his fellow pigs must take the milk and apples because they "contain substances absolutely necessary to the well-being of a pig." He further explains that many pigs "actually dislike milk and apples" and tells the questioning animals, "It is for your sake that we drink that milk and eat those apples." His physical "skipping from side to side" during such explanations parallels his "skipping" words, which are never direct and always skirt the obvious truth of the matter at hand. As the novel proceeds, he excuses Napoleon's tyranny and sullies Snowball's reputation, just as Napoleon desires. The most outrageous demonstration of his "skipping" is when he convinces the animals that Boxer was taken to a veterinary hospital instead of the knacker's.
