As far as could be seen, the usually solid earth was agitated by a slow wave-like motion, which became first tremulous, and then unspeakably violent, throwing half of the houses into heaps of ruins, and yawning into wide chasm-like fissures, from which mephitic sulphurous vapours issued. Shrieks and groans of anguish filled the air, a mournful interlude shrilly resounding at intervals above the subterranean thunder, as the terrified crowd rushed to the mole, to seek refuge on board the vessels in the harbour. Scarcely had they reached this hoped-for haven of safety, when the sea, treacherous as the heaving land, glided softly back, and then rushing forward with a terrific roar, submerged the mole with its panting terror-stricken occupants, and poured on in a foaming flood over the prostrate town, where it completed the havoc the earthquake had begun. It then rushed back almost more suddenly than it had advanced, the whole fearful deluge occupying only about five minutes. Again and again the earth quivered and shook, as if about to rend asunder and drop into some unfathomable abyss below, and again the sea dashed forward as if in frantic fury, and then as suddenly recoiled, the last time shewing a perpendicular wall of water forty-five feet high, capped by an angry crest of foam. This tremendous wave swept miles inshore, where it stranded the largest ships then lying in the harbour, one of them a United States frigate. In Arica Mr Squier equipped himself for a journey over the Cordilleras. Nothing can exceed the savage wildness of these mountains, or the difficulties and dangers of the long narrow passes that intersect them. Mr Squier says: 'I have crossed the Alps by the routes of the Simplon, the Grand St Bernard, and St Gothard; but at no point on any of them have I witnessed a scene so wild and utterly desolate as that which spreads out around La Portada.' It is the very acmé of desolation--treeless, shrubless, bare of grass, with scarcely a lichen clinging to the rugged sides of the huge cliffs. Pile upon pile towering to the sullen skies, rise ridges of dark-brown hills bristling with snowy peaks, from several of which long trails of smoke stream lazily out upon the air, shewing where the pent volcano surges in ominous life beneath the wintry wastes of snow. Descending from the Cordilleras, Mr Squier examined Tiaguanuco, the Baalbec of the New World; and from thence proceeded to Cuzco, the City of the Sun, the ancient capital of the Incas, which abounds with memorials of their vanished greatness. Here stood a magnificent temple of the sun, which was lined throughout with plates of gold, two of which, preserved as curiosities, were shewn to Mr Squier. The huge stones composing this and other massive buildings which yet remain are cut and fitted together with a precision which has been equalled, but never surpassed. So accurately do they fit, that it is impossible to pass the finest-bladed knife between their edges.
