They saw a vast oval of more than forty leagues' circumference, surrounded, like an amphitheatre, with a girdle of mountains. On the east rose the two proud volcanoes, Popocatepetl and Iztaccíhuatl, covered with perpetual snow, their sides clothed with forests. When the Aztecs came, one vast lake occupied the basin of the broad plateau, too wide to be called a valley, as well as too elevated, for the lowest part is more than six thousand feet above the level of the sea. They saw a rocky height rising above the wet soil near the lake, out of which were doubtless even then growing huge cypress-trees, _ahuehuetl_, making a dense and pleasant shade; a large spring of water flowed constantly from the rock. Here they stopped and named the place Chapultepec, which means the Hill of the Grasshopper. In the picture-writings of the Aztecs it is depicted as a small hill with a huge grasshopper standing all over it. Here the Mexicans, or Aztecs, remained for a few years, but their place was contested by the neighboring tribes, who also all of them saw the merits of the site, and valued as much as the new-comers the spring of sparkling water. The Mexicans made themselves odious by their religious practices, and a combined array of Chichimecs and other tribes dispossessed them of the Grasshopper Hill. They betook themselves to a group of low islands in the lake, and there led a miserable existence for many years, covered with rags, living on such fishes and insects as they could lay hold of from the lake, and dwelling in wretched huts made out of reeds and rushes. They were nothing more than the slaves of the Tepanecs and Culhuas, surrounding tribes, and it is extraordinary that from such a life they roused themselves to any thing better. In the course of a battle between two of their tyrant tribes, they, the miserable slaves, the despised eaters of insects, gave such proof of unconquerable valor on the side of their masters, that these were terrified and gave them their liberty. This was nearly one hundred years after they had been driven from Chapultepec. They now shook off the yoke of their oppressors, gathered themselves together, and leaving the wretched island where they had languished so long, set forth once more in search of a permanent dwelling-place.
