I am not sure which poem you are referring to here, but one poetical technique is called enjambment. This occurs when a line continues to the next line without a pause. Even if there is a stanza break in between, the lines are meant to be read continuously. For example, consider these lines from a poem by William Wordsworth called Beauteous Evening:
"The holy time is quiet as a Nun
Breathless with adoration; the broad sun
Is sinking down in its tranquility"
Here, Wordsworth is not intending that you pause after you read "Nun" or "sun." He wants you to read these lines as a continuous sentence or thought. Hope this helps.
Using Huck Finn as the narrator of the book allowed Mark Twain to add more life, excitement, and realism in his writings. We can only think how good Mark Twain was at languages by how he writes.
