t It may l)e mentioned iiert* that the silt and terrace deposits, 3,000 
feet above sea level, which Spencer mentions from Norway as proof 
of an analogous great submergence, are certainly not of marine 
origin, and are most i)robably analogous to the "parallel roads" in 
vScotland. They are known in many localities in the higher valleys of 
Norway and Sweden, but there is not one Scandinavian geologist who 
considers them as marine; tlie well marked marine area is much 
jower.
