The second tube should be bent to a right angle above the stopper and
its projecting end filed to a sharp point. Without removing the bag from
around the pistillate blossoms, the hybridizer forces the point of the
atomizer through the cotton wadding between bag and branch. The pollen
in the vial is blown through the tube into the bag in a cloud, covering
all the enclosed blossoms. It is advisable to repeat this on several
successive days to make certain of reaching the female blossoms during
their most receptive period.
