Not only is the mounting and forward drive of waves repeated in mountain forms, but also the whirlpools among the rocks when sea waves reach the shore. Says the famous French geographer, Reclus[22]:
"The centre of the Pyrenees resembles a great whirlpool around which the mountains rise like enormous waves."
[22] "The Earth."
Finally we might imagine that the mountains, like the mountain streams, hear the call of the sea and are stirred by it. For, again to quote from Ruskin's wonderful chapter on the nature of the thing we call a mountain:
"Behold as we look farther into it, it is all touched and troubled. The rock trembles through its every fibre, like the chords of an Æolian harp—like the stillest air of spring with the echoes of a child's voice. Into the heart of all those great mountains and through every tossing of their boundless crests and deep beneath all their unfathomable defiles, flows that strange quivering of their substance.
"'I beheld the mountains and lo they trembled; and all the hills moved lightly.'"

This picture shows mountain-peaks carved in folded strata in the Rocky Mountains in Montana. How well it illustrates Ruskin's grand lines.
