Methods of Destroying: the Ox-Eye Daisy.— The following observations are offered as based on experience: (1) When the infested field is in sod, turn it under and devote it to a corn crop. Or (at any time in the rotation) have re course to a hoed crop. (2) Resort to a bare fallow. This will de- stroy all the plants then living. The few seeds that may escape and germinate subse- quently, must, when they appear, be removed by the spud, as described in (3)

(3) When the above methods are inappli- cable, resort to the spud, running it under the root a short distance below the surface. 261. The Burdock.—The burdock is a perennial plant, with great rhubarb-like leaves, and large burs filled with seeds. Its seed is dissemin- ated by falling to the ground over which it is blown by the wind, or by the burs adhering to animals, by which they are carried from one place to another. 262. Methods of Destroying the Burdock.—The following observations are offered as based on experience: (i) Like the blue-weed, the burdock also cannot stand before the cultivation necessary for either a summer-fallow or a hoed crop. (2) But if it is found in bye-places, it is destroyed by being cut with a spade below the crown, before it has had a chance to form seed. Two or three years of this treatment will eradicate it utterly. 263. Pigfeon-Weed.—Pigeon weed, or red root, is an annual plant, with a branching disposition. It has a red root, and from this it derives one of its names. Its seeds are of great vitality, and as these ripen in June, the plant is most troublesome in wheat, rye, meadow land, and pasture. 264. Methods of Destroying Pigeon-weed.—The fol- lowing observations are oftered as based on experience: (l) For the fields that are infested let winter wheat and rye, '.
