Lousy Lane is a road which runs near Dr. Montgomery's house. It is bordered by "a handful of scraggly trees produce apples so sour that one only has to look at them to feel ill" and runs across a river said to be made almost entirely of mud. It smells strongly of horseradish from a nearby factory, later revealed to be part of Anwhistle Aquatics, manufacturing horseradish as an antidote to the Medusoid mycelium. It ends in a cul-de-sac.[source needed]
