scratched

stones are decidedly in the minority, and indeed _a close search will
often fail to show them_. Clearly, then, the till is not of the
nature of a terminal moraine. _Each stone_ in the 'till' gives
evidence of having been subjected to a grinding process. . . .

"We look in vain, however, among the glaciers of the Alps for such a
deposit. The scratched stones we may occasionally find, _but where is
the clay?_ . . . It is clear that the conditions for the gathering of
a stony clay like the I till' do not obtain (as far as we know) among
the Alpine glaciers. There is too much water circulating below the
ice there to allow any considerable thickness of such a deposit to
accumulate."[1]

But it is questionable whether the glaciers do press with a steady
force upon the rocks beneath so as to score them. As a rule, the base
of the glacier is full of water; rivers flow from under them. The
opposite picture, from Professor Winchell's "Sketches of Creation,"
page 223, does not represent a mass of ice, bugging the rocks,
holding in its grasp great gravers of stone with which to cut the
face of the rocks into deep grooves, and to deposit an even coating
of rounded stones and clay over the face of the earth.

On the contrary, here are only angular masses of rock, and a stream
which would certainly wash away any clay which might be formed.

Let Mr. Dawkins state the case:
