CHAPTER VI.
1607—1621.
Don Luis Velasco,—the Second,—Conde de Santiago and First Marques de Salinas, XI. Viceroy of Mexico. His Second Administration. 1607—1611.
Don Luis Velasco had been seven years viceroy of Peru since he left the government of Mexico, when he was summoned once more to rule a country of which he felt himself almost a native. He was tired of public life, and being advanced in years would gladly have devoted the rest of his existence to the care of his family and the management of his valuable estates in the colony. But he could not refuse the nomination of the king, and at the age of seventy, once more found himself at the head of affairs in New Spain.
The government of this excellent nobleman has been signalized in history by the erection of the magnificent public work, designed for the drainage of the valley, of which we spoke during the last viceroyalty. The results of Velasco's labors were permanent, and as his work, or at least a large portion of it remains to the present day, and serves to secure the capital from the floods with which it is constantly menaced, we shall describe the whole of this magnificent enterprise at present, though our description will carry us, chronologically, out of the period under consideration, and lead us from the seventeenth to the nineteenth century.
​The valley of Mexico is a great basin, which although seven thousand five hundred feet above the level of the sea, and of course subject to constant and rapid evaporation, is yet exceedingly humid for so elevated a region. No stream, except the small arroyo, on rivulet of Tequisquiac, issues from the valley, whilst the rivers PapaIotla, Tezcoco, Teotihuacan, Guadalupe, Pachuca and Guautitlan pour into it and form the five lakes of Chalco, Xochimilco, Tezcoco, San Cristoval and Zumpango. "These lakes rise by stages as they approach the northern extremity of the valley; the waters of Tezcoco, being, in their ordinary state, four Mexican varas and eight inches lower than the waters of the lake of San Cristoval, which again, are six varas lower than the waters of the lake Zumpango, which froms the northernmost link of this dangerous chain. The level of Mexico in 1803 was exactly one vara, one foot and one inch above that of the lake of Tezcoco, and, consequently, was nine varas and five inches lower than that of the lake of Zumpango; a disproportion, the effects of which have been more severely felt because the lake of Zumpango receives the tributary streams of the river Guautitlan, whose volume is more considerable than that of all the other rivers which enter the valley combined.
"In the inundations to which this peculiarity in the formation of the valley of Mexico has given rise, a similar succession of events has been always observed. The lake of Zumpango, swollen by the rapid increase of the river Guautitlan during the rainy season, forms a junction with that of San Cristoval, and the waters of the two combined burst the dykes which separate them from the lake of Tezcoco. The waters of this last again, raised suddenly more than a vara above their usual level, and prevented from extending themselves to the east and south-east, by the rapid rise of the ground in that direction, rush back towards the capital and fill the streets which approach nearest to their own level. This was the case in the years 1553, 1580, 1604 and 1607, in each of which years the capital was entirely under water, and the dykes which had been constructed for its protection destroyed."
Such is a topographical sketch of the country accurately given by a careful writer; and to protect an important region so constantly menaced with inundation, the viceroy now addressed himself. Accordingly he commissioned the engineer Enrique Martinez, in 1607 to attempt the drainage of the lake of Zumpango, by the ​stupendous canal now known under the name of the Desague de Huehuetoca.
"The plan of Martinez appears to have embraced two distinct objects, the first of which extended to the lakes of Tezcoco and San Cristoval, while the second was confined to the lake of Zumpango whose superfluous waters were to be carried into the valley of Tula by a subterraneous canal into which the river Guautitlan was likewise compelled to flow. The second of these projects only was approved by the government; and the line of the canal having been traced by Martinez between the Cerro or hill of Sincoque and the hill of Nochistongo to the north-west of Huehuetoca, where the mountains that surrounded the valley are less elevated than in any other spot,—the great subterraneous gallery of Nochistongo was commenced on the 28th of November, 1607. Fifteen thousand Indians were employed in this work, and as a number of air shafts were sunk, in order to enable them to work upon the different points at once, in eleven months a tunnel of six thousand six hundred metres in length, three metres five in breadth and four metres two in height, was concluded.
"From the northern extremity of this tunnel called la boca de San Gregorio, an open cut of eight thousand six hundred metres conducted the waters to the salto or fall of the river Tula, where, quitting the valley of Mexico, they precipitate themselves into that of Tula, from a natural terrace of twenty Mexican varas in height, and take their course towards the bar of Tampico where they enter the gulf of Mexico. An enterprise of such magnitude could hardly be free from defects, and Martinez soon discovered that the unbaked bricks, of which the interior of the tunnel was composed, were unable to resist the action of water, which, being confined within narrow limits, was at times impelled through the tunnel with irresistible violence. A facing of wood proved equally ineffectual, and masonry was at last resorted to; but even this, though successful for a time, did not answer permanently, because the engineer, instead of an elliptical arch, constructed nothing but a sort of vault, the sides of which rested upon a foundation of no solidity. The consequence was that the walls were gradually undermined by the water, and that the vault itself in many parts fell in.
"This accident rendered the government indifferent to the fate of the gallery which was neglected, and finally abandoned in the ​year 1623, when a Dutch engineer, named Adrian Boot, induced the viceroy to resume the old system of dyke and embankments, and to give orders for closing the tunnel of Nochistongo. A sudden rise in the lake of Tezcoco caused these orders to be revoked, and Martinez was again allowed to proceed with his works which he continued until the 20th of June, 1629, when an event took place, the real causes of which have never been ascertained."
"The rainy season having set in with unusual violence, Martinez, either desirous to convince the inhabitants of the capital of the utility of his gallery, or fearful, as he himself stated, that the fruits of his labor would be destroyed by the entrance of too great a volume of water, closed the mouth of the tunnel, without communicating to any one his intention to do so. The effect was instantaneous; and, in one night, the whole town of Mexico was laid under water, with the exception of the great square, and one of the suburbs. In all the other streets the water rose upwards of three feet, and during five years, from 1629 to 1634, canoes formed the only medium of communication between them. The foundations of many of the principal houses were destroyed; trade was paralyzed; the lower classes reduced to the lowest state of misery; and orders were actually given by the court of Madrid to abandon the town and build a new capital in the elevated plains between Tacuba and Tacubaya, to which the waters of the lakes, even before the conquest, had never been known to extend.
"The necessity of this measure was obviated by a succession of earthquakes in the dry year of 1634, when the valley was cracked and rent in various directions, and the waters gradually disappeared; a miracle for which due credit should be given to the Virgin of Guadalupe, by whose powerful intercession it is said to have been effected.
"Martinez, who had been thrown into confinement in 1629, was released upon the termination of the evils which his imprudence was said to have occasioned; and was again placed by a new viceroy,—the Marques de Cerralvo,—at the head of the works by which similar visitations were to be averted in future. Under his superintendence the great dyke, or Calzada of San Cristoval was put in order, by which the lake of that name is divided from that of Tezcoco. This gigantic work which consists of two distinct masses, the first, one league, and the second, one thousand five hundred varas in length, is ten varas in width or thickness ​throughout, and from three and a half to four varas in height. It is composed entirely of stone, with buttresses of solid masonry on both sides, and three sluices, by which, in any emergency, a communication between the lakes can be effected and regulated at the same time. The whole was concluded, like the gallery of Nochistongo, in eleven months, although as many years would now be required for such an undertaking. But in those days the sacrifice of life, and particularly of Indian life, in public works, was not regarded. Many thousands of the natives perished before the desague was completed; and to their loss, as well as to the hardships endured by the survivors, may be ascribed the horror with which the name of Huehuetoca is pronounced by their descendants.
"It is not our intention to follow the progress of the canal of Huehuetoca through all the various changes which occurred in the plans pursued with respect to it from 1637, when the direction of the work was again taken from Martinez and confided to the Franciscan monks, until 1767, when, under the viceroyalty of the Marques de Croix, the Consulado or corporate body of Mexican merchants, engaged to complete this great national undertaking. The necessity of converting the tunnel of Martinez into an open cut, had long been acknowledged, it having been found impossible to prevent the tunnel from being continually choked up by the sand and rubbish deposited by the water on its passage; but as the work was only prosecuted with vigor when the danger of an inundation became imminent, and was almost suspended in the dry years, two thousand three hundred and ten varas of the northern gallery remained untouched, after the expiration of one hundred and thirty years when the Consulado was intrusted with the completion of the arduous task. As the old line of the gallery was to be preserved, it became necessary to give the cut which was to be sunk, perpendicularly upon it, an enormous width at the top, in order to prevent the sides from falling in; and in the more elevated parts, between the mountains of Sincoque and the hill of Nochistongo, for the space of two thousand six hundred and twenty-four feet, the width, across, varies from two hundred and seventy-eight to six hundred and thirty feet, while the perpendicular depth is from one hundred and forty-seven to one hundred and ninety-six feet. The whole length of the cut from the sluice called the vertideros to the salto or fall of the river Tula, is sixty-seven thousand five hundred and thirty-seven feet or twenty-four thousand five hundred and thirty Mexican varas. The highest point of the hill of Nochistongo is that called Boveda Real, and it ​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. It is supposed that one-third of this sum would have proved sufficient to cover all the expenses, had Martinez been furnished in the first instance with the means of executing his project upon the scale which he had judged necessary; for it is in the reduced dimensions of the gallery of Nochistongo, which was never equal to the volume of water to which at particular seasons it afforded an outlet, that all the subsequent expenditure has originated."
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, ​together with two hundred Spaniards and Mestizos, to attack them in their fastnesses. Several skirmishes took place between the slaves and these forces, and at length the negroes yielded to the Spaniards,—craving their pardon, inasmuch as their "insurrection was not against the king,"—and promising that they would no longer afford a refuge to the blacks who absconded from the plantations. Velasco at once granted their request, and permitted them to settle in the town of San Lorenzo.
In 1610 and 1611, there were but few important incidents in the history of New Spain, which was now gradually forming itself into a regularly organized state, free from all those violent internal commotions, which nations, like men, are forced to undergo in their infancy. The viceroy still endeavored to ameliorate the condition of the Indians, and despatched a mission to Japan in order to extend the oriental commerce of Spain. The true policy of Castile would have been, instead of crushing Mexico by colonial restrictions, to have raised her gradually into a gigantic state, which, situated in the centre of America, on the narrowest part of the continent between the two oceans, and holding in her veins the precious metals in exhaustless quantities, would have surely grasped and held the commerce of the east and of Europe. Such would seem the natural destiny of Mexico if we examine her geographical features carefully; nor do we venture too much in predicting that the time will come when that destiny will be fulfilled.
Velasco was now well stricken in years and required repose. His master, appreciating his faithful services and his unquestionable loyalty, added to his already well earned titles that of Marques of Salinas, and creating him president of the Council of the Indies recalled him to Spain where he could pass in quiet the evening of his days, whilst he was also enabled to impart the results of his vast American experience to the king and court.
Fray Garcia Guerra, Archbishop of Mexico, XII. Viceroy of New Spain. 1611—1612.
Velasco, as an especial mark of royal favor, was desired to retain his power as viceroy until the moment of embarkation for Spain, and then to depose it in favor of the monk Garcia Guerra, who had been the worthy prior of a Dominican convent at Burgos ​in Spain, until he was nominated to the Archepiscopal See of Mexico. His government was brief and altogether eventless. He became viceroy on the 17th of June, 1611, and died on the 22d of February in the following year, of a wound he received in falling as he descended from his coach.
Don Diego Fernandez de Cordova, Marques de Guadalcazar. XIII. Viceroy of New Spain. 1612—1621.
Upon the death of the last viceroy, the Audiencia, of course, took possession of the government during the interregnum;—and, as it seems that this body of men was always doomed to celebrate its authority by acts of folly or cruelty, we find that soon after its accession to power the city was alarmed by the news of another outbreak among the negroes. The people were panic struck. A terrible noise had been heard in the streets of the metropolis during the night, and, although it was proved that the disturbance was entirely caused by the entrance, during the darkness, of a large drove of hogs, the Audiencia determined, nevertheless, to appease public opinion by the execution of twenty-nine male negroes and four negro women! Their withered and fetid bodies were left to hang on the gallows, tainting the air and shocking the eyes of every passer, until the neighborhood could no longer bear the sickly stench and imperiously demanded their removal.
The Marques de Guadalcazar took possession of the viceroyalty on the 28th of October, 1612, and his government passed in quiet engaged in the mere ordinary discharge of executive duties during the first four years, subsequent to which an Indian insurrection of a formidable character broke out in one of the departments, under a chief who styled himself "Son of the Sun and God of Heaven and Earth." This assault was fatal to every Spaniard within reach of the infuriate natives, who broke into the churches, murdered the whites seeking sanctuary at their altars, and spared not even the ecclesiastics, who, in all times, have so zealously proved themselves to be the defenders of their race. Don Gaspar Alvear, Governor of Durango, assembled a large force as soon as the viceroy informed him of the insurrection, and marched against the savages. After three months of fighting, executions and diplomacy, this ​functionary succeeded in suffocating the rebellion; but he was probably more indebted, for the final reconciliation of the Indians, to the persuasive talents of the Jesuits who accompanied the expedition, than to the arms of his soldiers.
The remaining years of this viceroyalty are only signalized by the founding of the city of Cordova,—whose neighborhood is renowned for the excellent tobacco it produces,—and for the construction of the beautiful aqueduct of San Cosmé which brings the sweet waters of Santa Fé to the capital. This monument to the intelligence and memory of Guadalcazar was completed in 1620, and, in March, 1621, the viceroy was removed to the government of Peru.
