No further clues needed - I took the time to work it out and found the quote! It's from Roverandom, and the passage names the speaker: Did this remind you of the snow in Switzerland at this time of year? :)

d and h added

Esty pokes Guinevere - I already solved it!

correct, of course !
 

*slaps head*
I'm sorry, I had only been looking at the bottom of the previous page, and didn't notice the next page at all.
Well, in town the snow really is grimy ! :p But in 2 weeks I'll go skiing in the mountains! :)

http://www.travar.de/Templates/Webpr...mages/idea.gif It's the description of Niggle's picture:
("innumerable" and "fantastic" were the clues ;) )
I remember this because it reminds me of Tolkien's description in the foreword of how the LotR developped .

*Esty applauds

Wonderful, Guinevere! Fast work! Yes, it is a lovely quote that fits in with the autobiographical character of Niggle. Your turn next.

*fühlt sich gebauchpinselt* :D Thank you Esty!

Well, I will do something completely unexpected and ask for the Ts, please. ;)

(I am very curious what anyone trying to translate your comment will think, Guinevere! :D )

Ah, that one was a bit tricky, but now I found it - it's Tom, speaking to the Troll in The Adventures of Tom Bombadil:

It's Roverandom speaking to the Man-in-the-Moon:

"I've got a pain in my inside," he said. "I want to go back to the little boy, so that his dream can come true."

Excellent, with so few letters to go by, Guinevere! I found that quote so cute - a very childlike definition of longing and homesickness. Now I look forward to your new quote!

Thank you, Esty! :)

Ts, please

lots of t's
