What's the rhyme scheme of the poem? The clouds by frank d sherman The sky is full of clouds to-day, And idly, to and fro, Like sheep across the pasture, they Across the heavens go. I hear the wind with merry noise Around the housetops sweep, And dream it is the shepherd boys,— They're driving home their sheep. The clouds move faster now; and see! The west is red and gold. Each sheep seems hastening to be The first within the fold. I watch them hurry on until The blue is clear and deep, And dream that far beyond the hill The shepherds fold their sheep. Then in the sky the trembling stars Like little flowers shine out, While Night puts up the shadow bars, And darkness falls about.
