The national flag of Great Rritain and Ireland, which combines the banner of St. Patrick with the crosses of St. George and St. Andrew. The word “jack” is most probably derived from the surcoat, charged with a red cross, anciently used by the English soldiery. This appears to have been called a “jacque,” whence the word “jacket,” anciently written “jacquit.” Some, however, without a shadow of evidence, derive tlie word from “Jacques,” the first alteration having been made in the reign of King James I. Wharton.
