Rh would be difficult when looking down from it, upon the stream below, and, following with the eye the vast opening through which it seeks an issue, to conceive that the whole is, indeed, the work of man, did not the mounds on either side, as yet but imperfectly covered with vegetation, and the regular outline of the terraces, denote both the recentness of its completion, and the impossibility of attributing it to any natural convulsion.

"The Obra del Consulado, as the opening cut is called, was concluded in the year 1789. It cost nearly a million of dollars; and the whole expense of the drainage from 1607 to the beginning of the present century, including the various projects commenced and abandoned when only partially executed,—the dykes connected with the desague,—and the two canals which communicate with the lakes of San Cristoval and Zumpango,—is estimated at six millions two hundred and forty-seven thousand six hundred and seventy dollars, or one million two hundred and forty-nine thousand five hundred and thirty-four pounds.

We have judged it better to group together in this place all the facts relative to this most important national work,—so as to afford the reader a complete picture of the undertaking,—than to relate the slow and tedious history of the work as it advanced to completion during the reigns of many viceroys. The present condition of the desague and its advantages will be treated in another portion of this work; and we shall therefore revert at once to the year 1609, in which a large number of negroes rebelled against the Spaniards. It seems that the blacks in the neighborhood of Cordova, who were in fact slaves on many of the hiciendas or plantations, having been treated in an inhuman manner by their owners, rose against them in great force, and gathering together in the adjacent mountains menaced their tyrannical task-masters with death, and their property with ruin. Velasco sent one hundred soldiers, one hundred volunteers, one hundred Indian archers,
