Well known as a cultivated plant from time immemorial; 

 invaluable for its fibre and oil. The fibre of the inner bark is 

 very strong and tough, is valuable for spinning, and is used 

 in the manufacture of fine linen threads and cloths, also a 

 great variety of coarser cords and fabrics. The seeds are the 

 source of linseed oil, and the residue, under the name of " oil 

 cake," is considered a valuable food for stock. Linseed meal 

 has important medicinal uses.
