Informative blurbs at the beginning and the end of the book tell about the man who was Davy Crockett, and about the time period in which he lived, and how legends grew out of the truth of the time.  Sandwiched between these blurbs is a tall tale describing how Davy wrestled to the death a gator who was longer than two steam ships, and had been terrorizing the Mississippi River until he met his match in Davy.  It’s a great example of voice, being told in a folksy drawl that sounds like an old-timer rocking on a front porch somewhere telling the tale, full of colloquialisms that suit the era.
