- Why, only last trip I was offered a refrigerating plant in Chicago!" - "Love, The Fiddler", Lloyd Osbourne.
- When the quantity of moisture in the air is small, the refrigerating process continues until frost is produced, and many a moonlight night in spring destroys half or even the whole of the fruit of a new season. - "Moon Lore", Timothy Harley.
- At Medora it was customary, when the Little Missouri was high, to ride to the western side on the narrow footpath between the tracks on the trestle; and after the Marquis built a dam nearby for the purpose of securing ice of the necessary thickness for use in his refrigerating plant, a venturesome spirit now and then guided his horse across its slippery surface. - "Roosevelt in the Bad Lands", Hermann Hagedorn.
