The cane became first known, through Marco Polo, in the middle of the thirteenth century; and it was soon after introduced into Nubia, Egypt and Ethiopia; whence, about the 15th century, it reached Europe. It was first planted in Sicily, and carried to Spain, Madeira, and the Canary Isles; and, twenty-eight years after the discovery by Columbus, it was introduced into Hayti, by Pedro Atienza, and speedily spread over the West Indies and other parts of America. THE SUGAR CANE is one of the most valuable agricultural products of Mexico, and we are convinced from personal observation that the estates in the _tierra caliente_, where it is chiefly raised, are the richest, as well as most beautiful, in the republic. There is scarcely a lovelier prospect in Mexico than that which spreads before the traveller as he descends from the northern mountains into the valley or Cuernavaca, which lies south of the valley of Mexico, and may be reached easily in the course of a day. On every side, as far as the eye can reach, fields of the freshest verdure are spread out, dotted with the white walls and towers of the magnificent _haciendas_, which have been founded in this valley ever since the conquest. Screened from the cold winds of the upper table land by the protecting barrier of mountains which hem in the vales of Mexico and Puebla, the valley of Cuernavaca basks, on their southern slopes and feet, in a tropical climate. Winter never destroys the foliage in this sheltered region. Pleasant streams gurgle through its midst and afford sufficient supplies for irrigation. On the plain the tender green of the young cane, waves in the sun-light like a mass of purest velvet; whilst the palm and the plantain mingle their [Illustration: MEXICAN FOREST SCENE.] pensile and massive foliage amid the densest groves of oranges, aloes, and forest trees. The valley of Cuernavaca is one of those picturesque regions which are so well calculated to bring back a fanciful beholder to the scenes he has conjured up in youth whilst perusing the story of Paul and Virginia, or the glowing descriptions of the Arabian Nights.
