52 THE STOCKFEEDER'S COMPANION 



ground-nut is grown largely in North America. It is 

 also called earth-nut and monkey-nut. The plant is 

 remarkable for the fact that after fertilisation of the 

 flower, the flower-stalk pushes the fruit into the ground, 

 where it ripens. The fruit consists of a sausage-shaped, 

 straw-coloured husk or pod about an inch long, with 

 two seeds or pea-nuts enclosed. These pea-nuts are 

 rich in oil (41 per cent), and on this account are utilised 

 as a source of oil. 



Sunflower Seed (Helianthus annuus}. The sun- 

 flower seed is largely imported from Russia, and 

 contains approximately 30 per cent, oil ; hence the oil 

 is often extracted. The seed is sometimes fed to 

 poultry. 



Rape Seed. This is the seed from rape, and comes 

 chiefly from Russia, Germany, Austria Hungary, and 

 East India, where it is grown on account of its richness 

 in oil. 



The seed contains 35 to 45 per cent. oil. It is apt 

 to contain mustard seed, which may cause harm to live 

 stock if present in quantity. It may also contain 

 considerable quantities of sand. 



The expressed oil is used very largely for lubricating 

 machinery, and the residual cake is rape cake. 



Kapok Seeds. These seeds are obtained from 

 a tropical plant called Eriodendron anfractuosum, 

 which is related to the cotton plant. It is largely 

 grown in Java, Sumatra, and the Philippine Islands, and 

 to a small extent in India, Ceylon, and Central 

 America. 



The seeds contain 24 to 26 per cent, oil, 22 to 24 

 per cent, albuminoids, and 20 to 22 per cent, fibre. 

 They are peculiarly-shaped seeds, dark in colour, and 

 approximately the size of vetches. The narrow end of
