What is Black Beauty's first impression of his new home?

From the text:

I was quite happy in my new place, and if there was one thing that I missed it must not be thought I was discontented; all who had to do with me were good and I had a light airy stable and the best of food. What more could I want? Why, liberty! For three years and a half of my life I had had all the liberty I could wish for; but now, week after week, month after month, and no doubt year after year, I must stand up in a stable night and day except when I am wanted, and then I must be just as steady and quiet as any old horse who has worked twenty years. Straps here and straps there, a bit in my mouth, and blinkers over my eyes.
