chapter 6 ,

From the text:

Kino lay as rigid as the tree limb. He barely breathed, and his eyes went to the place where he had swept out the track. Even the sweeping might be a message to the trackers. He knew these inland hunters. In a country where there was little game they managed to live because of their ability to hunt, and they were hunting him. They scuttled over the ground like animals and found a sign and crouched over it while the horseman waited. ch. 6
