[Footnote 4: "The province which constitutes the principal territory of Montezuma," (says Cortéz in his letter to Charles the V.,) "is circular, and entirely surrounded by lofty and rugged mountains, and the circumference of it is full seventy leagues. In this plain there are two lakes which nearly occupy the whole of it, as the people use canoes for more than fifty leagues round. One of these lakes is of fresh water, and the other, which is larger, is of salt water. They are divided, on one side, by a small collection of high hills, which stand in the centre of the plain, and they unite in a level strait formed between these hills and the high mountains, which strait is a gun-shot wide, and the people of the cities and other settlements which are in these lakes, communicate together in their canoes by water, without the necessity of going by land. And as this great salt lake ebbs and flows with the tide, as the sea does, in every flood the water flows from it into the other fresh lake as impetuously as if it were a large river, and consequently at the ebb, the fresh lake flows into the salt. "This great city of Temixtitlan, (meaning Tenochtitlan, Mexico,) is founded in this salt lake; and from terra firma to the body of the city, the distance is two leagues on whichever side they please to enter it. "It has four entrances, or causeways, made by the hand of man, as wide as two horsemen's lances. "The city is as large as Seville and Cordova. The streets (I mean the principal ones,) are very wide, and others very narrow; and some of the latter and all the others are one-half land and the other half water, along which the inhabitants go in their canoes; and all the streets, at given distances, are open, so that the water passes from one to the other; and in all their openings, some of which are very wide, there are very wide bridges, made of massive beams joined together and well wrought; and so wide that ten horsemen may pass abreast over many of them."--_Letters of Cortéz to Charles V._] CHAPTER IV. 1519-1520.
