In addition to writing, Frost continued to teach at Amherst College of Arts and Letters and during this period, he churned out his third collection of poetry - “Mountain Interval”. This collection also followed the footsteps of the previous collections that showed his deep regards for Mother Nature and his respects for people aspirations. He used imagery from the everyday life such as stars, houses, trees and brooks, among others. An example of a Frost’s poem that was inspired by nature in this collection was “Birches”. The speaker is said to have seen some birch trees that were being blown over by an ice storm. This reminded him (speaker) of time when he was a child and was swinging on the trees. In this piece, he has included unique and easily distinguishable comparisons of the ice storm and the child playing on the trees (Magill 722-723).
