Rainsford's first night of the hunt was spent "big tree with a thick trunk and outspread branches. He climbed up into the crotch and, stretching out on one of the broad limbs, after a fashion, rested. Rainsford was very careful not to leave any signs for Zaroff to follow.
On the first night that he's being hunted, Rainsford spends the whole night on the run from Zaroff. He rests in a tree at one point, and Zaroff tracks him but never looks up in the tree. This is when Rainsford realizes Zaroff is playing with him, so Rainsford then decides to set some traps. The first trap hurts Zaroff's shoulder, so he goes back to the chalet to get it seen to. At the Death Swamp, Rainsford builds the pit with the stakes and kills a dog. The next trap kills Ivan. At that point, Rainsford has to make the decision to jump off the cliff, and Zaroff goes back home.
Rainsford spends the first night of his hunt running away from General zaroff until he finds a big tree where he decides to rest in. The next morning, Gneral Zaroff comes passing the tree..... Rainsford thinks the general knows he's there
