Glass smells a buffalo carcass. Yummy. Unfortunately, it's already been picked clean by predators and is currently being feasted on by flies.
Throwing caution to the wind, Glass starts breaking its bones and sucking out the marrow, which happens to be "greenish" in tint (1.9.4).
Predictably, Glass spends the next few hours vomiting his brains out. It takes him a day and a half to fully recover.
With no other options, Glass starts setting up traps for small animals. He starts off by making deadfalls, which is the classic "rock propped up on a stick" method.
It takes him a while, but he eventually sets up three traps. He checks them the next morning and the first two are empty. Bummer! But what about the third?
The third trap actually worked perfectly, but when Glass approaches it, he's blasted in the face by a skunk whose leg had been snagged. Glass rushes to the river to wash off the stench.
As he thinks about how much easier this would have been if he had a rifle, Glass feels a Klingon-like desire for revenge rising in his stomach.
Glass tries a different type of trap next, this one often used by "Pawnee children" (1.9.42). He basically digs a hole and puts some rocks on top so it looks like a little den. He then starts crawling around the pit in an ever-shrinking circular pattern, driving any small creatures in the underbrush directly into his trap.
Not eager for another skunk surprise, Glass takes a stick and bashes repeatedly into the hole, killing anything inside. His take isn't huge—four mice and two squirrels—but it's something.
Glass builds a makeshift bow and spindle to start a fire and enjoys a nice, if a bit small, feast of roasted rodent.
