general as regards to pollen production. Instead of all of the anthers 
bursting when the bloom opens, the anthers of the outer cycles alone 
dehisce first, followed gradually by the other cycles as they come to 
maturity. Flowers of this sort are not completely damaged by one rain¬ 
storm, because only the loose pollen is washed away, and when the 
weather clears up the anthers of the inner cycles mature and are ready 
to supply all the pollen needed by its own flower and the flowers that 
might be in the vicinity.

For best results, the blooming periods of the different varieties should 
be coincident so far as possible. This is especially true when only a 
very few varieties are under consideration. The earliest and the last 
blooms require a pollinator equally as potent as do those blooms from 
which the main crop is expected. In the consideration of several to
