In reading The History of Middle Earth, and the early drafts of Lord of the Rings, there are some 'cold sweat moments' when you realize how horribly wrong it all might have gone - or perhaps it is just that a genius needs to make mistakes en route to a masterpiece.
Many of these relate to the character called Trotter - a friend of Gandalf whom the hobbits met at the Prancing Pony in Bree and who guides them to Rivendell.
Trotter eventually became the noble Numenorean heir to the throne of Gondor and Arnor we know as Aragorn - but he began as a brown skinned hobbit who wore wooden shoes.
The wooden shoes - whose clopping sound on the road explains the nickname of 'trotter' - seem (for reasons I cannot even begin to fathom) to have been taken by Tolkien as an immovable necessity to the story, and he expended considerable ingenuity in devising explanations for why a hobbit should be wearing clogs...
These matters come to a head in the draft chapter for the Council of Elrond (page 401 of The Return of the Shadow - volume 6 of The History of Middle Earth) :
Gandalf spoke long, making clear to
those who did not already know the tale in full the ancient history of the
Ring, and the reasons why the Dark Lord so greatly desired it.
gave an account of the finding of the
Ring in the cave of the Misty Mountains, and Trotter described his search for
Gollum that he had made with Gandalf's help, and told of his perilous
adventures in Mordor.
Thus it was that Frodo learned how
Trotter had tracked Gollum as he wandered southwards, through Fangorn Forest,
and past the Dead Marshes, until he had himself been caught and
imprisoned by the Dark Lord.
'Ever since I have worn shoes,' said Trotter with a shudder, and though he said no more Frodo knew he had been tortured and his feet hurt in some way...
Well, all this is bad. After all this build-up about the clogs we get the phrase 'Hurt in some way...
Lame, one might say.
But worse is yet to come.
The real, twenty-four carat cold sweat moment comes in Reference 20, where Christopher Tolkien reveals:
My father bracketed the passage from 'Ever since I have worn shoes' to 'hurt in some way', and wrote in the margin (with a query) that it should be revealed later that Trotter had wooden feet.
Go back and read that last sentence again...
Clogs would have been bad enough; but instead of the noble Aragorn, we very nearly had a mahogany-footed halfling.
Phew! (Wipes brow with large spotted handkerchief.)
