In a retrospect from the present time, it seems as if one of the causes that led to my conservative position was the extreme exaggeration of some glacialists, who found in glacial erosion a destructive agency competent to accomplish any desired amount of denudation - an opinion from which I recoiled too far. Since the publication of my previous essay I had gradually come to accept a greater and greater amount of glacial erosion in the regions of active ice motion; but in spite of this slow change of opinion, the maximum measure of destructive work that, up to last year, seemed to me attributable to glacier~ was moderate; and it was therefore with great surprise that I then came upon certain facts in the Alps and in Norway which demanded wholesale glacial erosion for their explanation.

The one is the incomparably limpid water of Petrarch's fountain; the other an offset from the river Durance, which has carried into the heart of this sun-burnt region the unequivocal mark of its birth amidst the perpetual snows of Monte Viso. This is the pulverizing action of ice. Most erroneously have those argued who object to this theory that ice cannot scratch quartz -ice is only the setting of the harder fragments, which first round, then furrow, afterwards polish, and finally scratch the surface over which it moves.

Rlitimeyer and A. Heim on this question are as follows: Riitimeyer gave an excellent account of hanging lateral valleys thirty years ago in his description of the valley of the Reuss {1869, 13-24). He recognized benches or Thalstufen on each side of the valley above the basal cliffs of the existing bottom trough, and regarded them as the remnants of a former, wide open valley floor. Side valleys of moderate fall enter the main valley about at the level of the Thalstufen, and their waters then cascade down over the basal cliffs to the Reuss.
