foghorn

noun, a deep sounding instrument for warning ships in fog (COD); see also horn

“In ’41 he went to the lighthouse. He still farmed a bit but he couldn’t do both. That’s just because back in those days you had to be up there, eh, with the old foghorn and that.”

“My great-great-grandfather and grandmother, they were lightkeepers out there. And they had a house down on Four Mile … They used to row out there and light the light. There was never a foghorn. But anyway, they got pneumonia one fall, and they died out there.”
