number of clusters outside the bags. Table 8 sliows the results of an 

 experiuient in hand pollinating with Angouleme pollen emasculated 

 flowers on the same tree. 



It will be noticed that the number of flowers pollinated, as well as 

 the number of clusters, is here recorded. The per cent of fruit is com- 

 puted directly from the number of flowers. The uncovered clusters in 

 the following table will also serve for comi)arison with the pollinated 

 flowers in table 8.

Eesult : 65.9 per cent. 



It may not be quite fair to compare these pollinated flowers with the 

 uncovered ones on the same tree, as shown in table 7, and attribute all 

 the difference to the change in pollen, since removing some of the flow- 

 ers in these clusters may have been of advantage to those remaining. 

 The general truth will, however, be brought out. It will also be seen 

 iu the tables tliat the larger the nund^er of clusters involved in an 

 experiment the greater its importance. The statements of per cents 

 secured should not all be considered of etxual importance. Eei)etition
