HAIR GRASS-A NUISANCE. I send sample of grass for name. Is it an annual? It is spreading rapidly. Seems to grow better in the shade than any other grass I know of; is very hard to cut with scythe. Some are getting alarmed, fearing it will run out other grasses on lawn and door-yard; not bad in cultivated grounds. M. B. MANTENO ILL., Oct. 30. Answer :- The specimen was sent to Prof. W. J. Beal, of the Michigan Agricultural College, who replies as follows: "The grass in question is Mulenbergia capillaris, (hair grass) and a nuisance. I have received six or more species of this genus for a name within a few years. In several cases the person sending has feared it because it was spreading and appeared troublesome. I have not heard, however, that it has amounted to much except in the shade of trees. None of them are annuals, but have underground stems which live over winter to shoot up the next spring. This is the first specimen received of this species."
