The Great Whale of Kansas is a story about a boy that lives in Kansas who likes digging bug holes. To him digging a hole is a sort of achievement. When he wanted to build a pond in his backyard, he uncovers a fossil which was unique.
The narrator's reaction to his pond first filling with water differ from his outlook at the end of the story shows that the narrator is excited at first but then becomes disappointed.
Because scops (oral storytellers) were telling their stories orally and not from a written account, they needed something that would allow them to easily remember those stories. This why you notice that tales or epics that were first told orally have a certain cadence that makes it easier to follow. This allows the storyteller to remember and it also allows the reader to follow along in a better way.
As an interesting side note, these story tellers would also sometimes put the stories to music as that was another way to tell the stories. They would start as ballads and the storyteller would play a tune while they sang the stories.
