The Hobbit - Queer lodgings

Inside the hall it was now quite dark. Beorn clapped in his hands, and in trotted four beautiful white ponies and several large, long-bodied grey dogs. [...]The dogs could stand on their hind-legs when they want and carry things with their fore-feet. Quickly they got out boards and trestles from the side walls and set them up near the fire.
Then baa-baa-baa! was heared, and in came some snow-white sheep lead by a large coal-black ram. One bore a white cloth in its mouth embroidered at the edges with figures of animals; other bore on their broad backs trays with bowls and platters andknives and wooden spoons. [...]
There they had a supper, or dinner such as the had not had since theyleft the Last Homely House in the West and saied good-bye to Elrond.
