Panther and Crane laid a wager. Panther said to Crane, "Let us see who can throw the farthest." "All right," Crane answered. They said, "Let us throw a hammer across a stream." Panther threw first, and he got it across, but when Crane stood ready to throw, he thought, "I can't get it across." The two had agreed that whichever did not succeed in getting the hammer across should be killed.
