subs. (American).A Confederate nickname for vessels of the Monitor type; first applied during the Civil War [186065]. Cf., TINCLADS (q.v.).
1871. DE VERE, Americanisms, p. 335. The great inventor has not made it known what induced him to choose the name [Monitor]: hence etymologists have evolved it out of their inner consciousness that he must have borrowed it from Grays Monitor Dracæna, a large lizard covered with impenetrable armour. Irreverent Confederates called the hideous-looking vessels CHEESE-BOXES, and apparently one designation is, etymologically, though not æsthetically, as good as the other.
