{*} [As little as did Clovis and his Franks, when that doughty warrior embraced Christianity.--M.] The Conquerors settled in such parts of the country as best suited their inclinations. Many occupied the southeastern slopes of the Cordilleras towards the rich valley of Oaxaca. Many more spread themselves over the broad surface of the table-land, which, from its elevated position, reminded them of the plateau of their own Castiles. Here, too, they were in the range of those inexhaustible mines which have since poured their silver deluge over Europe. The mineral resources of the land were not, indeed, fully explored or comprehended till at a much later period; but some few, as the mines of Zacatecas, Guanaxuato, and Tasco,--the last of which was also known in Montezuma’s time,--had begun to be wrought within a generation after the Conquest.[185] But the best wealth of the first settlers was in the vegetable products of the soil, whether indigenous, or introduced from abroad by the wise economy of Cortés. He had earnestly recommended the crown to require all vessels coming to the country to bring over a certain quantity of seeds and plants.[186] He made it a condition of the grants of land on the plateau, that the proprietor of every estate should plant a specified number of vines on it.[187] He further stipulated that no one should get a clear title to his estate until he had occupied it eight years.[188] He knew that permanent residence could alone create that interest in the soil which would lead to its efficient culture, and that the opposite system had caused the impoverishment of the best plantations in the Islands. His various regulations, some of them not a little distasteful to the colonists, augmented the agricultural resources of the country by the addition of the most important European grains and other vegetables, for which the diversified climate of New Spain was admirably adapted. The sugar-cane was transplanted from the neighboring islands to the lower level of the country, and, together with indigo, cotton, and cochineal, formed a more desirable staple for the colony than its precious metals. Under the sun of the tropics, the peach, the almond, the orange, the vine, and the olive, before unknown there, flourished in the gardens of the table-land, at an elevation twice as great as that at which the clouds are suspended in summer above our heads. The importation of a European fruit or vegetable was hailed by the simple colonists with delight. The first produce of the exotic was celebrated by a festival, and the guests greeted each other, as on the appearance of an old familiar friend, who called up the remembrance of the past and the tender associations of their native land.[189]
