1796  (1911)  I gathered fox berries. They grow like small red currants on a delicate plant.
1950  "We've three things to brag about here," said a man at a filling station. "First, Newcomb, then the quarry, and then fox berries. . . ."
1964  And to this day I don't know just what a foxberry is, either. All I know is that foxberries grow wild on low bushes, and they taste quite like ordinary cranberries, only with more flavor.
