All the animals were now present except Moses, the tame raven, who slept on a perch behind the back door. When Major saw that they had all made themselves comfortable and were waiting attentively he cleared his throat and began: "Comrades, you have heard already about the strange dream that I had last night. But I will come to the dream later. I have something else to say first. I do not think, comrades, that I shall be with you for many months longer, and before I die I feel it my duty to pass on to you such wisdom as I have acquired. I have had a long life, I have had much time for thought as I lay alone in my stall, and I think I may say that I understand the nature of life on this earth as well as any animal now living. It is about this that I wish to speak to you."
