  The neutrino propagation through the Earth is investigated in the framework
of the democratic neutrino theory. In this theory the neutrino mixing angle
theta-1-3 is approximately determined, which allows one to make a well defined
neutrino oscillogram driven by the 1-3 mixing in the matter of the Earth.
Significant differences in this oscillogram from the case of models with
relatively small theta-1-3 are discussed.
