Such has been their fate under the Spanish conquerors, who took no care to enforce the admirable system for their preservation adopted by the Incas. Yet the broken portions that still survive, here and there, like the fragments of the great Roman roads scattered over Europe, bear evidence to their primitive grandeur, and have drawn forth the eulogium from a discriminating traveller, usually not too profuse in his panegyric, that "the roads of the Incas were among the most useful and stupendous works ever executed by man." 46The system of communication through their dominions was still further improved by the Peruvian sovereigns, by the introduction of posts, in the same manner as was done by the Aztecs. The Peruvian posts, however, established on all the great routes that conducted to the capital, were on a much more extended plan than those in Mexico. All along these routes, small buildings were erected, at the distance of less than five miles asunder,47 in each of which a number of runners, or chasquis, as they were called, were stationed to carry forward the despatches of government.48 These despatches were either verbal, or conveyed by means of quipus, and sometimes accompanied by a thread of the crimson fringe worn round the temples of the Inca, which was regarded with the same implicit deference as the signet ring of an Oriental despot.49The chasquis were dressed in a peculiar livery, intimating their profession. They were all trained to the employment, and selected for their speed and fidelity. As the distance each courier had to perform was small, and as he had ample time to refresh himself at the stations, they tart over the ground with great swiftness, and messages were carried through the whole extent of the long routes, at the rate of a hundred and fifty miles a day. The office of the chasquis was not limited to carrying despatches. They frequently brought various articles for the use of the Court; and in this way, fish from the distant ocean, fruits, game, and different commodities from the hot regions on the coast, were taken to the capital in good condition, and served fresh at the royal table.50 It is remarkable that this important institution should have been known to both the Mexicans and the Peruvians without any correspondence with one another; and that it should have been found among two barbarian nations of the New World, long before it was introduced among the civilized nations of Europe.51By these wise contrivances of the Incas, the most distant parts of the long-extended empire of Peru were brought into intimate relations with each other. And while the capitals of Christendom, but a few hundred miles apart, remained as far asunder as if seas had rolled between them, the great capitals Cuzco and Quito were placed by the high roads of the Incas in immediate correspondence. Intelligence from the numerous provinces was transmitted on the wings of the wind to the Peruvian metropolis, the great focus to which all the lines of communication converged. Not an insurrectionary movement could occur, not an invasion, on the remotest frontier, before the tidings were conveyed to the capital, and the imperial armies were on their march across the magnificent roads of the country to suppress it. So admirable was the machinery contrived by the American despots for maintaining tranquillity throughout their dominions! It may remind us of the similar institutions of ancient Rome, when, under the Caesars, she was mistress of half the world.
