"the old swimmin' hole"
by james whitcomb riley

shows the change in the speaker and the swimming hole.

The way the poem is structured allows the author to show both the changes to the swimming hole and the changes to the speaker's life. We know that the speaker is different because he claims he is now an old man, and that the passage of time can be seen in his face. We also know that the swimming hole is different because the spot is now crossed by the bridge of the railroad.
