  The existence of the cosmic ray Halo in our Galaxy has been discussed for
more than half a century. If it is real it could help to explain some puzzling
features of the cosmic ray flux: its small radial gradient, nearly perfect
isotropy and the low level of the fine structure in the energy spectra of the
various particles. All these features could be understood if: (a) the Halo has
a big size (b) cosmic rays in the Halo have a unform spatial distribution and
(c) the cosmic ray density in the Halo is comparable or even higher than that
in the Galactic Disk. The main topic of the paper concerns the present status
of the anisotropy and a model for its formation. In our model the extremely
small amplitude of the dipole anisotropy is due to the dilution of the
anisotropy in the Disk by the dominating isotropic cosmic rays from the Halo.
Some minor deviations from complete isotropy in the sub-PeV and PeV energy
regions point out to the possible contribution of the Single Source with the
phase of its first harmonic opposite to the phase produced by the Disk.
