[ Sinclair / King Coal ]
Upton Sinclair (1878 - 1968) was a prolific American writer and political activist best known for The Jungle (1905), a scathing critique of early 20th-Century working conditions and the exploitation of the poor.
King Coal — a politically charged work (as were most of Sinclair's novels) about a Colorado coal miners' strike — has one (metaphorical) reference to Newfoundlands (Book 3, Section 1):
He was round-faced, like a full moon, and as jolly as Falstaff; when you got to know him better, you discovered that he was loyal as a Newfoundland dog.
