likely to be fecundated, and there may not be enough

 When the fruit is ripe the seeds should be planted 

 and cared for as heretofore 

 directed for growing plants 

 from seed, except that es- 

 pecial care should be used 

 in all the operations to 

 avoid mixture, or injury to

and accidents are liable to 



occur all along the line, so that the result of a 

 summer's work may be, in the end, only a few 

 plants, most or all of which are worthless. Yet 

 persistent effort in this line should be encouraged, 

 and in time the results are likely to repay all the at- 

 tempts made. 



During the summer of 1890 considerable work was 

 done by the writer in crossing different varieties and 

 species of raspberries and blackberries in the hor- 

 ticultural gardens at Cornell University. A num- 

 ber of plants came through to fruiting age. Notes 

 were taken in the summer of 1894 on all those which 

 had then begun to fruit. The substance of these 

 notes is given below, and may prove of interest as 

 showing some of the tendencies exhibited. In writ- 

 ing the records of crosses, the seed -bearing parent 

 is placed first. For example, "Gregg X Shaffer" 

 means that pistils of Gregg received pollen from 

 Shaffer.
