A weed is a plant growing where we wish something else to grow, and a plant may, therefore, be a weed in some locations and not in others. The mullein is grown in greenhouses in England as the American velvet- plant. Our grandmothers considered "butter-and-eggs," a pretty posy, and planted it in their gardens, wherefrom it escaped, and is now a bad weed wherever it grows. A weed may crowd out our cultivated plants, by stealing the moisture and nourishment in the soil which they should have; or it may shade them out by putting out broad leaves and shutting off their sunlight. When harvested with a crop, weeds may be unpala- table to the stock which feed upon it; or in some cases, as in the wild parsnip, the plant may be poisonous. Each weed has its own way of winning in the struggle with our crops, and it behooves us to find that way as soon as possible in order to circum- vent it.
