The weeds which infest grass-lands vary in differ-ent sedlions. In the North, whiteweed {Erigeron phila-delphicus) is one of the most troublesome. In pasturesthis can be held in check by mowing, but when ameadow becomes infested with it the best remedy isto plow it up. Sorrel (^Rumex acetosella) is probablythe next most troublesome weed in grass-lands in theNorth. It is particularly troublesome in old grass-lands, and its presence is believed to indicate an acidcondition of the soil. A good application of lime, tocorredl acidity, and manure or fertilizer to produce avigorous growth of the grasses and clovers, is said to. FIG. 3—QUACK-GRASS MEADOWS AND PASTURES 51 be the remedy for it. Sorrel seldom appears in grass-lands that are so treated as to keep up a vigorousgrowth. Its presence is a pretty good indication thatit is time to plow up the sod and run it through arotation which will give an opportunity to kill weedsand put the land in good heart. Some old timothymeadows are much overrun with plantain, especiallyon worn soils where the grass makes a feeble is unwise to keep meadows down on such soils afterplantain becomes troublesome. In middle latitudes and in the Southern Statesbroom-sedge {Andropogon virginicus) is probably themost troublesome weed in grass-lands. It may bekept out by prompt removal with the hoe or spud assoon as it appears. Broom-sedge doe
