While the third line is:

The sound device that Frost uses is alliteration. Alliteration refers to the repetition of the same initial consonant sounds within a group of words. Alliteration is commonly used in order to cause an emotional effect or to increase the persuasiveness of a text. Alliteration is also known as "head rhyme."
