Hence the fragments appear to have travelled from the head of the valley; but in reality it seems more probable that they have been hurled down from the nearest slopes; and that since, by a vibratory movement of overwhelming force, the fragments have been levelled into one continuous sheet.

"Nous n'avons pas ete moins saisis d'etonnement a la vue de l'innombrable quantite de pierres de toutes grandeurs, bouleversees les unes sur les autres, et cependant rangees, comme si elles avoient ete amoncelees negligemment pour remplir des ravins.

On ne se lassoit pas d'admirer les effets prodigieux de la nature." "Pernety" page 526.) If during the earthquake which in 1835 overthrew Concepcion, in Chile, it was thought wonderful that small bodies should have been pitched a few inches from the ground, what must we say to a movement which has caused fragments many tons in weight to move onwards like so much sand on a vibrating board, and find their level?

An inhabitant of Mendoza, and hence well capable of judging, assured me that, during the several years he had resided on these islands, he had never felt the slightest shock of an earthquake.) I have seen, in the Cordillera of the Andes, the evident marks where stupendous mountains have been broken into pieces like so much thin crust, and the strata thrown on their vertical edges; but never did any scene, like these "streams of stones," so forcibly convey to my mind the idea of a convulsion, of which in historical records we might in vain seek for any counterpart: yet the progress of knowledge will probably some day give a simple explanation of this phenomenon, as it already has of the so long thought inexplicable transportal of the erratic boulders which are strewed over the plains of Europe.
I have little to remark on the zoology of these islands.
