"He was feeling very low now, low and despondent, and taking all the circumstances into consideration it seemed to him that the best thing to do was to step into the park and take a look at the ducks on the Serpentine.  He had often found the spectacle of these agreeable birds act as a sedative in times of mental stress, soothing the soul and bringing new life and courage. And, indeed, there is always something very restful about a duck. Whatever earthquakes and upheavals may be afflicting the general public, it stands aloof from them and just goes on being a duck."
