deeply buried in the soil although the seeds are scattered on the 

 surface of the soil. This is also well illustrated in the tips of 

 raspberry bushes which come in contact with the soil through 

 the bending of the stalk. Roots strike out from the tip and when 

 thoroughly established in the earth the older portions contract 

 and bury the tip in the soil. In the same way seedlings of various 

 plants are slowly pulled down into the earth so that they finally 

 become planted at considerable depths.
