The Meat ledger is an optional artifact in the back room of the butcher shop in Lakeside Resort. After Joel picks up Ellie's backpack, look at the shelf on the right; the ledger is on the middle shelf.
A long list of dates and weights in pounds, with a few scribbled reactions: a big haul in one summer, a good spring, and a worried line when the totals drop.
Read in the butcher shop where Ellie's bag turned up, the ledger points to what the hunters have been storing to survive the winter.
