Common northward in shallow lakes and in the borders of slow 

 streams, also found in Siberia and Japan. Qual.ty of grain fully 

 equal to the common rice, but dark in color; more difficult to col- 

 lect, as the grain drops, a few kernels at a time, as soon as ripe. 

 Gathered by Indians ; attractive to water-fowl. At the South it is 

 cut for hay, offering two large crops in one season.
