On the coast of Sweden, it has been ascertained that iron rings fixed to rocks which formerly served for the fastening of boats are at present much too high. Flat cliffs on which, according to ancient documents, seals used to be clubbed while enjoying the warm sunbeam, are now quite out of the reach of these amphibious animals. In the years 1731, 1752, and 1755, marks were hewn in some conspicuous rocks, which after the lapse of half a century were found to have risen about two feet higher above the level of the sea. This phenomenon is confined to part of the coast, so that it is clearly the result of a local and slowly progressive upheaving. Whilst a great part of Scandinavia is thus slowly but steadily rising, the shores of Chili have been found to rise convulsively under the influence of mighty volcanic shocks. Thus after the great earthquake of 1822, the whole coast, for the length of a hundred miles, was found to be three or four feet higher than before, and a further elevation was observed after the earthquake of Feb. 21st, 1835. While to the north of Wolstenholme Sound, Kane remarked signs of elevation, a converse depression was observed as he proceeded southwards along the coast of Greenland, Esquimaux huts being seen washed by the sea. The axis of oscillation must be somewhere about 77° N. lat. At Keeling Island, in the Indian Ocean, Mr. Darwin found evidence of subsidence. On every side of the lagoon, in which the water is as tranquil as in the most sheltered lake, old cocoa-nut trees were undermined and falling. The foundation-posts of a store-house on the beach, which the inhabitants had said stood seven years before just above high-water mark, were now daily washed by the tide. Earthquakes had been repeatedly remarked by the inhabitants, so that Darwin no longer doubted concerning the cause which made the trees to fall, and the store-house to be washed by the daily tide. On the columns of the temple of Serapis, near Puzzuoli, the astonished naturalist sees holes scooped out by Pholades and Lithodomas, twenty-four feet above the present level of the sea. These animals are marine testacea, that have the power of burying themselves in stone, and cannot live beyond the reach of low-water. How then have they been able to scoop out those hieroglyphic marks so far above the level of their usual abodes? for surely marble originally defective was never used for the construction of so proud an edifice. Alternate depressions and elevations of the soil afford us the only key to the enigma. Earthquakes and oscillations, so frequent in that volcanic region, must first have lowered the temple into the sea, where it was acted upon by the sacrilegious molluscs, and then again their upheaving powers must have raised it to its present elevation. Thus, even the solid earth changes its features, and reminds us of the mutability of all created things.
