This is addressed in the article. "Paul Gravett writes in his new book about Tove Jansson: ‘Her Gollum towered monstrously large, to the surprise of Tolkien himself, who realized that he had never clarified Gollum’s size and so amended the second edition to describe him as ‘a small, slimy creature’."
We have Jansson to thank for the clarification, it seems!
The man took retcons as an intellectual challenge. Sometimes the retcon itself spun off a whole new story. But it makes The Hobbit really incompatible with its own sequel, even after his changes. (You have to read it as having a very unreliable narrator.)
Perhaps even Bilbo himself. :) One can imagine him telling a heavily fictionalized version of his adventures to some impressionable young hobbits.
Actually - in the creative process did he kick off the Hobbit then expand into the world building as an after thought and turn the one ring into this wild expansive creative endeavor? I always assumed it had been pre-built in his mind then spilled out in ink (As a sequence of events).
It's doubtless still possible to find that version, I read it in an old country library that had it on the shelf since the 1950s.
> There are of course other very minor changes. For instance, Gandalf tells Bilbo to bring out the chicken and tomatoes in the unrevised edition vs. the chicken and pickles in the revised edition. But I'll skip over these inconsequential changes.
Bit of medievalism there (tomatoes being a Colombian Exchange thing).
There's something so fundamentally European about potatoes, despite being (comparatively) new there. And British in particular. They're stodgy, bland, filling, comforting, and really tasty in a dull way. They displaced things like turnips, which had too much flavor and a dispiriting watery texture.
He could so easily have written that passage for turnips, but it would have been less comforting. (It is often read as if the word "potato" was used to translate some extinct native-European root vegetable, but I find that doubtful.)
> Now it is a curious fact that this is not the story as Bilbo first told it to his companions. To them his account was that Gollum had promised to give him a present, if he won the game; but when Gollum went to fetch it from his island he found the treasure was gone: a magic ring, which had been given to him long ago on his birthday. Bilbo guessed that this was the very ring that he had found, and as he had won the game, it was already his by right. But being in a tight place, he said nothing about it, and made Gollum show him the way out, as a reward instead of a present. This account Bilbo set down in his memoirs, and he seems never to have altered it himself, not even after the Council of Elrond. Evidently it still appeared in the original Red Book, as it did in several of the copies and abstracts. But many copies contain the true account (as an alternative), derived no doubt from notes by Frodo or Samwise, both of whom learned the truth, though they seem to have been unwilling to delete anything actually written by the old hobbit himself.
