And now, the sum -of it all is this : Encourage in every way crosses within 

 the limits of the variety and in connection with change of stock, expecting 

 increase in vigor and productiveness ; hybridize if you wish to experiment, 

 but do it carefully, honestly, thoroughly, and do, not expect too much ! Ex- 

 tend Darwin's famous remark to read : Nature abhors both perpetual self- 

 fertilization and hybridization.
