Summary and Analysis of the poem To One Who Has Been Long in City Pent:-

The poet describes the experience of a city-dweller who goes out to the countryside on a holiday. After a long stay in the city, he is delighted as he moves and breathes in the open atmosphere of the countryside. The sight of the clear blue sky fills heart with joy. There is no dust and smoke, no din and bustle as in the city. He prays to God in gratitude. When he feels tired he lies down on a bed of soft wavy grass and reads a sweet love-story. At that moment he feels he is the happiest man on earth.
At the end of the day, the city-dweller must return to the city. While returning home, he hears the sweet notes of the nightingale and sees the patches of clouds sailing across the sky. He has enjoyed the day so much that he cannot understand how the day has rolled by quickly. He feels sad for the sweet day has passed by rather too soon.
