THE LAW OF CIRCULATION. the unseen wind, has fallen as a downy snow-flake upon the lofty mountain, where, penetrated by a solar ray, it has become again a little globule of water, and the chilly wind, following the sun, has converted this globule into a crystal; and the crystal takes up its wandering course again, seeking the ocean.
But where its movement was once rapid, it is now slow; where it then flowed with the river miles in an hour, it will now flow with the glacier not more in centuries; and where it once entered calmly into the sea, it will now join the world of waters in the midst of a violent convulsion.
We have thus seen that the iceberg is the discharge of the Arctic river, that the Arctic river is the glacier, and that the glacier is the accumulation of the frozen vapors of the air. We have watched this river, moving on in its slow and steady course from the distant hills, until at length it has reached the sea; and we have seen the sea tear from the slothful stream a monstrous fragment, and take back to itself its own again.
