Taraxacum dens-teoWis. Dandelion, (p.) An intro duced plant, and now so extensively naturalized in our grass-plots, fields, and meadows that although not very obnoxious as a weed, it will be found a difficult task to extirpate it. The leaves and flower buds are frequently used, wilted, as a salad, and boiled as greens, and the root has been much employed recently in domestic econ omy, and is esteemed a pleasant and salutary substitute for the coffee berry.
Lobelia injtata. Eye-bright, Indian tobacco, (b.) A native weed possessing acrid properties, and sometimes employed as an emetic, and as an expectorant in asthma. Andromeda mariana. Stagger-bush, (s.) This native shrub is very abundant in the sandy districts of New Jersey, where it is reputed to be injurious to sheep when the leaves are eaten by them, producing a disease called the staggers. The evidence on this point ie not quite conclusive, but if established would cause the hush to be deservedly ranked among the pernicious plants Ptantago major. Common plantain, way-bread, (p.) This foreign plant is remarkable for accompanying civil ized man, growing along his foot-paths and flourishing around his settlemen' e. It is alleged that onr aborigines call it the white man's foot, from that circumstance. Another foreign species, the P. tanceolata, known as English plantain, rib-wort, ripple-grass, aad buckhoni plantain, is becoming psrticularly abundant in our upland meadows or clover grounds. The farmer shouldkeep its seeds from mingling with those of the red clover, and thus injuring the sale of clover seed in the market Teroma radicans. Trumpet-flower, (p.) This showy native climber ie often cultivated and admired in the northeastern States, hut in the West, along the Ohio i river and its tributaries, it is regarded as an intolerable nuisance.
rerbascwn thaps eta. Common Mullets, (b.) An intro duced, homely weed in our pastures and cultivated grounds. There is no surer evidence of a slovenly and negligent farmer than fields overrun with mulleins. As the plant produces a vast number of seeds it can only be kept in due subjection by eradication before the Trait is mature. There is another species called moth mullein, V. blattaria, more slender, and equally worthless, becom ing frequent in our pastures.
Linaria vulgarts. Toad-flax, Ranstead weed. (p.) A rather showy, but foetid weed, said to have been introduced into Pennsylvania by a Mr. Ranstead, from Wales, as a garden flower. It inclines to form large, dense patches in our pastures by means of its creeping roots, which take almost exclusive possession of the soil.
Nepel a cataria. Catmint, cat-nip, (p.) This is com mon about old settlements. Another perennial species, Glechama, (Benth..) called ground-joy, and gill, is also common iu moist, shaded places about farmhouses. Lamium amplexicaule. Dead nettles, hen-bit, (a.)

Leonurus cardiaca. Motherwort, (p.) A homely, ob noxious weed, found in waste places about houses and farm-yards.
Teucriurn Canadense. Wood-sage, germander, (p.) This native plant, which is frequently seen in low, shaded grounds along streams, where it is harmless, has recently got into the fields of some of the best farms of eastern Pennsylvania, where it is now regarded as an obstinately persistent nuisance.
Echium vulgare. Blue-weed, vipers bugloss, blue devils, (e.) A showy, but vile weed, extenalvily natural ized in some portions of our country, especially in Mary land and in the Shenandoah Valley, Va. Wherever it makes its appearance the farmers should act promptly on the Ovidian maxim, Principlis obsta, etc.: Meet and resist the beginning of evil.
Echinospermumlappula. Stick-seed, beggar's lice, (a.) The slovenly farmer is apt to get practically and vexa tiously acquainted with this obnoxious native weed in consequence of its racemes of bur-like fruit entan„ling the manes of his horses and the fleeces of his sheep.
Convolvulus arvensis. Bind-weed, (p:) This foreign plant has been introduced into some portions of our Country, and will give the farmers much trouble if they do not carefully guard against it.
Cuseula epilioum. Dodder, flax-vine, (a.) This re markable parasitic plant, somewhat resembling copper wire in appearaoce, was introduced with ourflax croP, and wag formerly a great pest in that crop, by winding round and entangling branches of stalks so as to spoil them; but the vine has become rare, and has nearly died out since the culture of flax has declined among us.
Solanum nigrum. Night-shade, (a.) Frequent in shaded, waste places about dwellings. It is reputed to be deleterious in its properties, and ought, therefore, to be excluded from the vicinity of all farm-houses, where its berries may tempt children to pluck and eat.
Solarium Carolinense. Horse Nettle, (p.) An exceed ingly pernicious weed, and the roots are so penetrating and so tenacious of life that it is difficult to get rid of. It was probably introduced from the South by Humphrey Marshall into his botanic garden at Marshalltou; Pa, whence it has gradually extended itself round the neigh borhood, and forcibly illustrates the necessity of caution in admitting mere botanical curiosities into good agricul tural districts.
Datura stramonium. Thorn Apple, Jamestown (or Jimson) weed, (a.) Two varieties of this coarse, foetid, narcotic plant (which is probably of Asiatic origin) are common among us as an obnoxious weed, and they should be carefully excluded from the vicinity of all farm houses.
Enslenia albtida. Whitish Enslemia, (p.) This twining plant, allied to the Asclepius or Milk-weed family, and as yet nnknown to the farmers of the Eastern States, is reported by Prof. Short, a distinguished botanist of Kentucky, to be an intolerable nuisance on the farms along the river banks in Ohio, Illinois, etc.
