In The Portable Phonograph by Walter Van Tilburg Clark, the exact quantity of various objects is frequently given. Concerning objects which appears in fours:
A small red fire is describes as coming from the burning of "four blocks of poorly aged peat." Later, the number of peat blocks is increased as another two are placed in the fire.
"Four men were seated cross-legged" around this fire, against an earthen bench.
Later in the story, "four fine, leather-bound books" are described as being wrapped in burlap.
Finally, a doctor is said to see, between the clouds of the sky, "four stars flying," with one of them quickly becoming again obscured by a flying cloud.
In total, Clark describes four distinct sets of things as appearing in fours.
