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 [Footnote 19: Sarmiento, Relacion, Ms., cap. 21. - Garcilasso, Com.
