The poem "The Cloud" by P. B. Shelley is a comprehensive explanation of the functions that a cloud performs for the creatures to survive on Earth. The poet has described what a cloud does in a day and night in such an elaborative manner that it seems as if we are listening to a person, named, for instance, Mr. Cloud, telling about the burdens of his life. By reading this poem, we realize that the Earth, the Sun, the Moon, the Stars, all of these make use of clouds in one way or the other. It is the clouds that make the sky beautiful for us and shower us with water so that our crops would grow. By calling the cloud the "daughter of the Earth and Sky", the poet is emphasising the role of the cloud in keeping the two intact. Although the verses in the poem do not rhyme much, they give a smooth flow when you read the poem in one go!
