ROW'EN, n. [Qu. Heb. רען, to be green, to thrive.]

1. Rowen is a field kept up till after Michaelmas, that the corn left on the ground may sprout into green. Notes on Tusser. Turn your cows that give milk into your rowens, till snow comes. Mortimer.
2. In New England, the second growth of grass in a season. We never apply the word to a field, nor to a growth of corn, after harvest, nor is the word ever used in the plural. The first growth of grass for mowing is called the first crop, and the second rowen.
