Superstition vs. Progress

The novel contrasts the superstitious beliefs of the Guernsey community—who see Gilliatt as a 'marcou' or devil-touched, and the steamboat as an 'atheistical construction'—with the practical, forward-thinking ingenuity of characters like Lethierry and Gilliatt.

The Durande, as a steamship, symbolizes progress, while the superstitious fears of the islanders regarding the Douvres reef represent the lingering power of superstition.

The community's superstitious view of Gilliatt contrasts with his practical skills and knowledge of the sea.

The chapter contrasts the enduring superstitions of the Channel Islands with the 'enlightenment of the nineteenth century,' highlighting the persistence of belief in sorcery and demonic visits.

The Bû de la Rue is haunted until the woman moves in; the locals accept her with proverbs like 'Witch's candle is as good as devil's torch,' blending superstition with practical acceptance.
