circle of little milk pitchers set close together with their lips point- 

 ing outward. 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

 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.*
