I can’t rmember if Tree Beard was saying something to this effect when he was throwing stones at Isengard, or if it was Gandalf when he was remembering his fight with the Balrog.
But the quote has something to do with going over rock and stone…but I doubt Tolkien would have used the two in the same sentence together…as they basically mean the same thing. But his acumen for good verbage may have allowed him to do so…
Any Ideas? If this is too obscure feel free to tell me to Piss Off. 
“Stock and Stone” is what he said. Stock being a somewhat esoteric way of saying stream, I think.
In German über Stock und Stein (“over stick and stone”) is a very common and ancient alliteration meaning something like “off-road” or “through rough terrain.” I suspect that Tolkien uses “stock” in the in the first sense listed on this page in an English equivalent of the phrase.
IIRC, some of the maps in the books show streams (in the Shire, again, IIRC) with “stock” as part of their names.
Thats exactly it! Stock and Stone… Thank you!
And the line is something about Treebeard welcoming Gandalf to sacked Isengard and saying “Wood and water, stock and stone I can manage, but there is a wizard to deal with here.” (meaning Saruman)
There’s the Stock-brook, but isn’t that a stream that runs by the village of Stock?
It was when Sam said to Frodo, “I’ll show you my stock and stone, if you show me yours.”
Tolkien humor. Heh! Heh!
