but do not taste amiss in salads. Johnson * says the leaves are often employed by cotmtry

 to the whole of Europe, northern Asia and Arctic America, extending to Vermont and 

 Wisconsin. It has a piquant savor and is used as water cress. It is recorded as culti- 

 vated in the vegetable garden in France by Noisette,^ 1829, and by Vilmorin,'" 1883, yet,

 and as having become naturalized to a limited extent, a fact which implies a certain culti- 

 vation. Its seed is not offered in our catalogs.
