Answer:
The need for rest after work.
Step-by-step explanation:
William Carlos Williams' poem "The Corn Harvest" is a poem of short lines which describes a worker resting comfortably under the shade of a tree. Robert Frost's poem "After Apple Picking" also describes a worker resting after a long day's work of picking apples.
The given excerpt from both poems describe how the worker(s) needs rest after the heavy work they had been doing. Williams describes the painting of a young reaper who is "enjoying his /noonday rest/ completely/ relaxed / from his morning labors". Frost's poem also mentions a worker who is "done with apple-picking now. / Essence of winter sleep is on the night". Thus, both poems/ excerpts show the need of a deserved rest of the corn harvester and the apple picker.
