The many seeds are widely distributed by being blown over the snow and carried in hay and other crops. By some farmers it is considered one of the worst weeds with which they have to deal in bottom corn lands. Remedies: pulling or cutting before the blossoms appear; burning the mature plants before fall plowing; cultivation of hoed crops. The bast, or inner fibrous bark, of this-weed is a jute substi- tute which may be made into twine, rope and paper. In China the plant is cultivated for this fibre, which is exported under the name of China jute. The fibre from young plants takes dye readily and is fine enough to work into yarn for carpet fillings and coarse fabrics. Experiments in the cultivation and manufacture of the fibre have been made in Illinois and New Jersey. The cultivation was successful but the enterprises failed on account of the lack of economical machinery for extracting the fibre.* The St. John's-wort Family.—HYPERICACEiE.
