Vague and visionary as these speculations must seem to many, to others who are acquainted with the enormous glaciation to which America has been subjected they will appear to be based on substantial truths. The immense accumulation of ice over both poles, reaching far down into the temperate zones, in some meridians encroaching on the tropics, and in Equatorial America certainly all the land, lying 2000 feet above the level of the sea, supporting great glaciers, involve conditions which must have greatly drained the sea. Lands now submerged must have been uncovered, and on the return of the waters at the close of the glacial period many a peopled lowland must have been overwhelmed in the nearly universal deluge.

WE got back to Ocotal, from Depilto, before dark, and made arrangements for setting out on our return to the mines the next morning. Whilst sitting under the corridor, looking across the pretty flower-garden at the glowing western sky, illumined by the last rays of the setting sun, a poor fettered criminal, holding up by means of a string the thick chain that bound together his ankles, came limping along, with a soldier behind him armed with gun and bayonet. He had been brought out of prison to beg. In most of the towns of Nicaragua no food is given to the prisoners, whether convicted or merely charged with crime. Those that have no money to buy food are sent out every day with an armed escort to beg. The prisoner that hobbled up to me was under twenty years of age, and had been convicted of murder and condemned to death. He had appealed against the sentence to a higher court, but I was told that there was scarcely any chance of a decision in his favour, and that he would probably be shot in a day or two. Notwithstanding his critical position, he was lively and cheerful, and when I gave him a small piece of silver was as overjoyed as if he had got news of his reprieve. Jumping away, his clanking fetters making ghastly music, he gleefully showed to his guard the coin that would probably procure him food the few days he had to live. His wretched appearance, impending fate, and shocking levity had chased away the peaceful feelings with which I had watched the quiet sunset; but as he hobbled off, night, like a pall, fell over the scene; the trembling stars peeped out from the vault of heaven, and soon a million distant orbs proclaimed that the world was but a grain of dust in the vast universe, that the things of earth were but for a moment, and, as a shadow, would pass away.
