  We explore further the proposal in paper I of this series that the
confinement time of cosmic ray nuclei in the Milky Way is determined by their
interaction with dark matter molecular clouds rather than by their escape from
the halo, as is assumed in conventional models of cosmic ray propagation. The
same proposal can be made for cosmic ray electrons. This proposal leads to a
specific age distribution for the electrons which is in agreement with Tang's
(1984) observations of the electron spectrum at high energies but not with
Nishimura et al's (1980) earlier data, which lead to a flatter spectrum.
However, the simplest leaky box and diffusion models disagree with both sets of
data so that our trapping model is supported if Tang's data are correct.
