This was what they had to tell the governor. Far away towards the Pacific Ocean there stood, in a beautiful and most fertile valley, the capital of a great and powerful empire, called by its inhabitants 'Tenochtitlan,' but known to the Europeans only by its other name of 'Mexico,' derived from 'Mexitli,' the war-god of the Aztecs. These Aztecs seem to have come originally from the north, and after many wanderings to have halted at length on the south-western borders of a great lake, of which there were several in the Mexican valley. This celebrated valley was situated at a height of about 7,500 feet above the sea, and was oval in form, about 67 leagues in circumference, and surrounded by towering rocks, which seemed to be meant to protect it from invasion. It was in the year 1325 that the Aztecs paused upon the shore of the lake, and saw, as the sun rose, a splendid eagle perched upon a prickly pear which shot out of a crevice in the rock. It held a large serpent in its claws, and its broad wings were opened towards the rising sun. The Aztecs saw in this a most favourable omen, and there and then set about building themselves a city, laying its foundations upon piles in the marshy ground beside the lake, and to this day the eagle and the cactus form the arms of the Mexican republic.

The allies were completely successful, and this led to an agreement between the states of Mexico, Tezcuco, and Tlacopan, that they should support each other in all their wars, and divide all the spoils between them. This alliance remained unbroken for over a hundred years and under a succession of able princes the Aztec dominion grew, till at the coming of the Spaniards it reached across the continent, from the Atlantic to the Pacific Ocean. The Aztecs had many wise laws and institutions, and were indeed in some respects a highly civilised community. When their emperor died a new one was chosen from among his sons or nephews, by four nobles. The one preferred was obliged to have distinguished himself in war, and his coronation did not take place until a successful campaign had provided enough captives to grace his triumphal entry into the capital, and enough victims for the ghastly sacrifices which formed an important part of all their religious ceremonies. Communication was held with the remotest parts of the country by means of couriers, who, trained to it from childhood, travelled with amazing swiftness. Post-houses were established on the great roads, and the messenger bearing his despatches in the form of hieroglyphical paintings, ran to the first station, where
