To quickly assess the difficulty of the text, read a short excerpt:
Rock-foldings vary in size from tiny bends an inch in depth, to great wrinklings or creasings of the earth's crust, extending through miles of country. Many a range of mountains is an example of such huge wave-like bendings, each crease or wrinkle, divided by a hollow from the next, being thousands of feet in depth. If no after-change took place, it would be possible to trace in unbroken continuance the lines of the bent layers, running up each mountain and down each hollow. Take half-a-dozen p...ieces of thick cloth, and fold them backwards and forwards into several massive plaits, to make the matter more clear. Each piece of cloth rising and falling through the bends will picture a layer rising and falling through the mountain-folds. But in reality the upper layers cannot be so traced, for mountains do not remain unchanged. Frost and rain, wind and torrent, glacier and avalanche, are ever pursuing their work of destruction. The mountains are lower, now than they were a hundred years ago, for they are incessantly losing a part of their material.
