midnight
All the trees were thick-boled and slippery , he could n't have climbed them on a one-G world . The sheltered spots that he investigated , under fallen trees and beneath thick bushes , were just as wet as the rest of the forest . In the end he curled up on the leeward side of a tree , and fell asleep , shivering , with the water dripping off him . The rain stopped around midnight and the temperature fell sharply . Jason woke sluggishly from a dream in which he was being frozen to death , to find it was almost true . Fine snow was sifting through the trees , powdering the ground and drifting against him . The cold bit into his flesh , and when he sneezed it hurt his chest .
