I. The glaciers do not produce striated stones.
II. The glaciers do not produce drift-clay.
III. The glaciers could not have formed continental sheets of "till."
IV. The glaciers could not have existed upon, and consequently could not have striated, the mountain-tops.
V. The glaciers could not have reached to the great plains of the continents far remote from valleys, where we still find the Drift and drift-markings.
VI. The glaciers are limited in number and confined in their operations, and were utterly inadequate to have produced the thousands of square miles of drift-débris which we find enfolding the world.
