This chapter is a science fiction story about a hunter named Eckels, who pays money to join a hunting party that will travel back to the late Jurassic Era, on a guided safari to kill a Tyrannosaurus rex. Although Eckels is initially excited about the hunt, when the monstrous Tyrannosaur approaches, he loses his nerve. Travis tells him he cannot leave, but Eckels panics, steps off the path and runs into the forest. Realizing that Eckels has fallen off the path, (...) Travis threatens to leave him in the past unless he removes the bullets from the dinosaur's body, as they cannot be left behind. He frantically pleads with Travis to take him back into the past to undo the damage, but Travis explains that the time machine cannot return to any point in time that has already been visited. Travis raises his gun, and there is “a sound of thunder”. (shrink)
