Bertie Wooster quotes a poem

I always wondered where Bertie Wooster found this statement, which he made< I believe, about Aunt Agatha's country place: "Where every prospect pleases, and only man is vile."

What though the spicy breezes Blow soft o'er Ceylon's isle; Though every prospect pleases, And only man is vile; In vain with lavish kindness The gifts of God are strown; The heathen in his blindness Bows down to wood and stone.

Turns out it is, as they say, from a missionary hymn, by a Bishop, no less.

I don't know why I am surprised--Bertie did win a Scripture Prize (a statue of the Infant Samuel at prayer) when he was a boy. He waas obviously well informed about things ecclesiastical.
