If the ice will bear a goose before Christmas, it will not bear a duck afterward.
Originally the tenth month, December now closes the year.
If Christmas Day be bright and clear, there'll be two winters in the year.
The writer Saunders warned in 1679, "In December, Melancholy and Phlegm much increase, which are heavy, dull, and close, and therefore it behoves all that will consider their healths, to keep their heads and bodies very well from cold."
Robert Burns splendidly wrote in 1795: "As I am in a complete Decemberish humor, gloomy, sullen, stupid."
Logan Pearsall Smith (1865-1946)
