This is another of those grasses with a dual character, a most 

 valuable plant under certain conditions, and a veritable pest 

 when growing where it is not wanted. It is too well 

 known to need any description, and we will only add 

 that we regard it as a valuable pasture-grass for the 

 eastern part of the State at least, but its intro- 

 duction into new land should be made with caution 

 on account of its habit of taking complete possession 

 of the soil, and the difficulty presented in extermin- 

 ating it. It is strictly a summer grass here, for its 

 Fig. 11. leaves and stems are turned brown by the first frosts 



rjM^/o«^/>arf//f)/j of autumn. It is propagated by means of sets or 

 rooting stems. These are chopped up with a 

 cutting-knife, and then sown broadcast or dropped in shallow 

 furrows and lightly covered with earth. For holding steep 

 banks, or binding sandy soil subject to wash, this grass isespeci- 

 allvvaluable.
