But, if less successful in exploring the heavens, the Incas must be admitted to have surpassed every other American race in their dominion over the earth. Husbandry was pursued by them on principles that may be truly called scientific. It was the basis of their political institutions. Having no foreign commerce, it was agriculture that furnished them with the means of their internal exchanges, their subsistence, and their revenues. We have seen their remarkable provisions for distributing the land in equal shares among the people, while they required every man, except the privileged orders, to assist in its cultivation. The Inca himself did not disdain to set the example. On one of the great annual festivals, he proceeded to the environs of Cuzco, attended by his Court, and, in the presence of all the people, turned up the earth with a golden plough, - or an instrument that served as such, - thus consecrating the occupation of the husbandman as one worthy to be followed by the Children of the Sun. *18

The nobles, also, it seems, at this high festival, imitated the example of their master. "Pasadas todas las fiestas, en la ultima llevavan muchos arados de manos, los quales antiguamente heran de oro; i echos los oficios, tomava el Inga an arado i comenzava con el a romper la tierra, i lo mismo los demas senores, para que de alli adelante en todo su senorio hiciesen lo mismo, i sin que el Inga hiciese esto no avia Indio que osase romper la tierra, ni pensavan que produjese si el Inga no la rompia primero i esto vaste quanto a las fiestas.' Conq. i. Pob. del Piru, Ms.]
The patronage of the government did not stop with this cheap display of royal condescension, but was shown in the most efficient measures for facilitating the labors of the husbandman. Much of the country along the sea-coast suffered from want of water, as little or no rain fell there, and the few streams, in their short and hurried course from the mountains, exerted only a very limited influence on the wide extent of territory. The soil, it is true, was, for the most part, sandy and sterile; but many places were capable of being reclaimed, and, indeed, needed only to be properly irrigated to be susceptible of extraordinary production. To these spots water was conveyed by means of canals and subterraneous aqueducts, executed on a noble scale. They consisted of large slabs of freestone nicely fitted together without cement, and discharged a volume of water sufficient, by means of latent ducts or sluices, to moisten the lands in the lower level, through which they passed. Some of these aqueducts were of great length. One that traversed the district of Condesuyu measured between four and five hundred miles. They were brought from some elevated lake or natural reservoir in the heart of the mountains, and were fed at intervals by other basins which lay in their route along the slopes of the sierra. In this descent, a passage was sometimes to be opened through rocks, - and this without the aid of iron tools; impracticable mountains were to be turned; rivers and marshes to be crossed; in short, the same obstacles were to be encountered as in the construction of their mighty roads. But the Peruvians seemed to take pleasure in wrestling with the difficulties of nature. Near Caxamarca, a tunnel is still visible, which they excavated in the mountains, to give an outlet to the waters of a lake, when these rose to a height in the rainy seasons that threatened the country with inundation. *19

"Sacauan acequias en cabos y por partes que es cosa estrana afirmar lo: porque las echauan por lugares altos y baxos: y por laderas de los cabecos y haldas de sierras q estan en los valles: y por ellos mismos atrauiessan muchas: unas por una parte, y otras por otra, que es gran delectacio caminar por aquellos valles: porque parece que se anda entre huertas y florestas llenas de frescuras."

Most of these beneficent works of the Incas were suffered to go to decay by their Spanish conquerors. In some spots, the waters are still left to flow in their silent, subterraneous channels, whose windings and whose sources have been alike unexplored. Others, though partially dilapidated, and closed up with rubbish and the rank vegetation of the soil, still betray their course by occasional patches of fertility. Such are the remains in the valley of Nasca, a fruitful spot that lies between long tracts of desert; where the ancient water-courses of the Incas, measuring four or five feet in depth by three in width, and formed of large blocks of uncemented masonry, are conducted from an unknown distance.
The greatest care was taken that every occupant of the land through which these streams passed should enjoy the benefit of them. The quantity of water allotted to each was prescribed by law; and royal overseers superintended the distribution, and saw that it was faithfully applied to the irrigation of the ground. *20
