"If glaciers descended, as they did, on both sides of the great
Alpine ranges, then we would expect to find the same results on the
plains of Northern Italy that present themselves on the low grounds
of Switzerland. But this is not the case. On the plains of Italy
there are no traces of the stony clay found in Switzerland and all
over Europe. Neither are any of the stones of the drift of Italy
scratched or striated."[2]

But, strange to say, while, as Geikie admits, no true "till" or Drift
is now being formed by or under the glaciers of Switzerland,
nevertheless "till" is found in that country _disassociated from the
glaciers_. Geikie says:

"In the low grounds of Switzerland we get a dark, tough clay, packed
with scratched and well-rubbed stones, and containing here and there
some admixture of sand and irregular beds and patches of earthy
gravel. This clay is quite unstratified, and the strata upon which it
rests frequently exhibit much confusion, being turned up on end and
bent over, exactly as in this country the rocks are sometimes broken
and disturbed below till. The whole deposit has experienced much
denudation, but even yet it covers considerable areas, and attains a
thickness varying from a few feet up to not less than thirty feet in
thickness."[1]
