In Chapter 10, Strider, after encountering the hobbits in the Prancing Pony and the subsequent attack by the Nazgul on their room, the hobbits find out later that the stables too, were attacked, with the horses and ponies being run off. What I love, is that Tolkien goes into a couple paragraphs about what happens to the horses and ponies that were turned loose.
This is completely irrelevant to the hobbits or the continuation of their journey, but Tolkien thought enough of it to include it giving not only minor closure to the ponies, but also of Mr. Butterbur back at the inn. This happens again in the next chapter, as Strider and the Hobbits make camp in the dell near Weathertop. Strider tells the hobbits tales of Gil-galad, Tinuviel, Beren, and Luthien. The history of which he speaks isn't really relevant to any part of their own journey, but it gives great insight into part of the history, within Middle-earth.Bill Ferny’s price was twelve silver pennies; and that was indeed at least three times the pony’s value in those parts. It proved to be a bony, underfed, and dispirited animal; but it did not look like dying just yet. Mr. Butterbur paid for it himself, and offered Merry another eighteen pence as some compensation for the lost animals. He was an honest man, and well-off as things were reckoned in Bree; but thirty silver pennies was a sore blow to him, and being cheated by Bill Ferny made it harder to bear.
As a matter of fact he came out on the right side in the end. It turned out later that only one horse had been actually stolen. The others had been driven off, or had bolted in terror, and were found wandering in different corners of the Bree-land. Merry’s ponies had escaped altogether, and eventually (having a good deal of sense) they made their way to the Downs in search of Fatty Lumpkin. So they came under the care of Tom Bombadil for a while, and were well-off. But when news of the events at Bree came to Tom’s ears, he sent them to Mr. Butterbur, who thus got five good beasts at a very fair price. They had to work harder in Bree, but Bob treated them well; so on the whole they were lucky: they missed a dark and dangerous journey. But they never came to Rivendell.
An completely non-related to any of the above, we know how devoted Sam is to Frodo, and see him stand up to many enemies of the Fellowship, but one of the scenes I like most is when they deal with Bill Ferny. Just great stuff.
Sam turned quickly. ‘And you, Ferny,’ he said, ‘put your ugly face out of sight, or it will get hurt.’ With a sudden flick, quick as lightning, an apple left his hand and hit Bill square on the nose. He ducked too late, and curses came from behind the hedge. ‘Waste of a good apple,’ said Sam regretfully, and strode on.
