ON THE NUMBER OF RICE SHOOTS. 



The shoots produced from seedlings obtained from a large ear 

 grown on tlie main shoot of the mother plant, are always fewer 

 than those produced from seedlings from smaller ears on the side 

 shoots of the same plant. This fact, I observed from the experiment 

 made by me at Komaba in 1893, the method of which will be 

 described in a paper entitled " On the Selection of Seeds." I here 

 quote only the result of the experiment : —
