"On Sunday afternoons the city pours forth its legions to breath the fresh air and enjoy the sunshine of the parks and rural enjoyments of a London citizen on Sunday, but to me there is something delightful in beholding the poor prisoner of the crowded and dusty city, enabled thus to come forth once a week and throw himself upon the green bosom of nature. He is like a child restored to the mother's breast; and they who first spread out these noble parks and magnificent pleasure-grounds which surround this huge metropolis, have done at least as much for its health and morality, as if they had expended the amount of cost, in hospitals, prisons, and penitentiaries." Washington Irving.
