The earth has accumulated above them to the depth of two or three feet, so that their position is like that of the Roman pavements so often found in Europe; and we may guess, from what we saw exposed, how great must be the number of such remains still hidden, and how vast a population must once have inhabited this plain, now almost deserted.
Two days afterwards we came back. In the ploughed fields in the neighbourhood we made repeated trials whether it was possible to stand still in any spot where there was no relic of old Mexico within our reach; but this we could not do. Everywhere the ground was full of unglazed pottery and obsidian; and we even found arrows and clay figures that were good enough for a museum. When we left England, we both doubted the accounts of the historians of the Conquest, believing that they had exaggerated the numbers of the population, and the size of the cities, from a natural desire to make the most of their victories, and to write as wonderful a history as they could, as historians are prone to do. But our examination of Mexican remains soon induced us to withdraw this accusation, and even made us inclined to blame the chroniclers for having had no eyes for the wonderful things that surrounded them.
