It is shown that the orientation of the dust grain body relative to its angular momentum J by the Barnett relaxation effect and the orientation of J relative to the interstellar magnetic field, by action of anisotropic gaseous fluxes, which always exist in space, is more effective than the orientation of the Davis-Greenstein mechanism. The linear interstellar polarization, which arises by scattering of radiation on oriented grains, is directed along the galactic magnetic field.
