Such is the information which we may collect from this mineral
description of the Russian Dominions.
If we compare some of the Oural mountains with the general strata of
the Russian plains, then, as to the contained minerals, we may find a
certain diversity in those two places; at the same time, no greater
perhaps than may be found betwixt two different bodies in those same
plains, for example, chalk and flint. But when we consider those bodies
of the earth, or solid strata of the globe, in relation to their proper
structure and formation, we surely can find in this description nothing
on which may be founded any solid opinion with regard to a different
original, however important conclusions may perhaps be formed with
regard to the operations of the globe, from the peculiar appearances
found in alpine.
From this detail of what is found in the Oural mountains, and in the
gradation of country from those mountains to the plains of Russia, we
have several facts that are worthy of observation. First extensive
mountains of jasper. I have a specimen of this stone; it is striped red
and green like some of our marly strata.
