This is a variety of cress, of quick growth, used as lettuce. On a rich,
finely-pulverized soil, sow the seeds in drills, fifteen inches apart,
and cover very lightly. Sow thick and water in dry weather. For use, cut
the tops while they are very tender. A second crop will grow, but
inferior to the first. The water-cress, growing spontaneously by rills
and springs, is a kind of wild peppergrass, and is by some persons more
esteemed than the garden variety. We prefer early lettuce to cresses or
peppergrass, and see no reason for their cultivation, but their rapid
growth.
