The perennials that follow cultivated crops are mostly such as have root- stocks or other underground parts that are car- ried by the tools; as bindweed, quack-grass and nut-grass. The weeds of dooryards are mostly perennial or, at least, biennial, as docks, bur- dock, plantains, self-heal, round-leaved mallow. In the accompanying pictures. Figs. 134 to 148 show annuals; Figs. 149 to biennials; Figs. 155 to 171 perennials. Whenever any area becomes badly infested weeds, it is safe to assume that the place should be given a radical change of treatment. Areas long used for garden are likely to become very weedy: seed down the place and make the garden somewhere else for a time. A patch of Canada thistles can be killed by seeding down heavily and mowing for a few years. Meadows badly infested with carrot, daisy or hawkweed (paint-brush or hieracium), or dandelion should be broken up, thor- oughly tilled and put in rotation until it is safe to lay them down to grass again. Roadsides and waste places should be kept clean. Most states or localities have laws to compel property owners to mow the roadsides. It is probable that these weedy roadsides are less real menace to farming lands than is popularly supposed; but the laws should be enforced, nevertheless, for the effect of attractive roadsides in elevating public taste is everywhere worth consideration. It would not be right to leave the impression that all weedy fields are necessarily poorly managed fields. In humid climates it is usually better that ground be bearing plants than that it be idle. Nature covers all the waste and raw places; and nat
