There are two distinct parts. What does each part describe? The first two stanzas describe a game of "Hide and Seek" between the father and the boy, and the last two, the father's intense longing for the boy whom he has lost.
What kind of day is described in the first stanza? A bright and calm June day.
What things suggest this? Sleeping trees, still winds, wandering clouds, "noonday silence".
What does the writer represent the trees and the winds to be? Persons—the trees having the ability to sleep, and the winds to move or keep still. This is called personification.
What are "fleecy clouds"? Clouds that are white and downy.
The poet speaks of them as "flocks". What is the comparison intended? The comparison of the clouds to flocks of white sheep that, instead of wandering across a meadow, are wandering across the sky.
What does the word "wandered" suggest? That the clouds are moving along slowly and leisurely without any purpose in view. They are doing this because the "winds are still".
What is meant by saying that they "Have wandered past the hill"? They have gone below the horizon at the hilltop and cannot be seen. The sky is thus clear of clouds.
What causes "the noonday silence"? The heat of the mid-day has silenced even the songs of the birds. Compare Keats:
When all the birds are faint with the hot sun
And hide in cooling trees.
