In "The Quick One" in The Scandal of Father Brown by G. K. Chesterton, the author was describing two strange men entered a hotel with beach, saying:
Two quaintly assorted figures did, indeed, enter that quiet hotel on that sunny afternoon; one being conspicuous in the sunlight, and visible over the whole shore, by the fact of wearing a lustrous green turban, surrounding a brown face and a black beard; the other would have seemed to some even more wild and weird, by reason of his wearing a soft black clergyman’s hat with a yellow moustache and yellow hair of leonine length. He at least had often been seen preaching on the sands or conducting Band of Hope services with a little wooden spade; only he had certainly never been seen going into the bar of an hotel.
I found that "Band of Hope" is a charity that educates children and young people about drug and alcohol abuse.
But I can't get the link between "little wooden spade" and "educating teetotalism"?
Or do clergymen usually use spades?
