It turns out when Gale said 'smaller' he really meant it. Jim had no frame of reference here but comparing the tiny booklet to the some of the full sized journals left in his pack it really is an eighth of the size. There's no way Jim would be able to read or write this tiny but it DOES make for far more room in his pack.

"That's amazing!"

"You can't Use the books like that, what's the difference between just leaving them at camp?" Shadowheart muses, but Jim's excitedly gesturing to Gale all the while.

"Gale's just said he can change them back easily. Think of all the space we can save! AND if we find larger tools or equipment that could prove useful for the camp, we might actually be able to drag it back in a smaller state! It's brilliant."
