The Stem Finally Selected 



The direct color photograph print above shows the stem 

 of the final white blackberry. By comparing its color with the 

 color of other stems shown, it will be seen that the dark, purplish-brown 

 of the black Lawton has given way to the light greenish stem of the final 

 white blackberry. The color of the stem, it should be understood, is 

 only a guide to the color of the berry which is later to be produced. It 

 does not form the basis oj an absolute, fixed law, for outcroppings oj 

 old heredity sometimes appear in the stem but not in the fruit. The selec- 

 tion by the stems, is, however, of sufficient certainty to warrant its use in 

 such experiments as the production oj the white blackberry. Where it 

 Jailed as a guide in three or Jour cases, it succeeded in 

 hundreds or thotisands oJ cases.
