The Peruvians showed a similar spirit of enterprise in their schemes for introducing cultivation into the mountainous parts of their domain. Many of the hills, though covered with a strong soil, were too precipitous to be tilled. These they cut into terraces, faced with rough stone, diminishing in regular gradation towards the summit; so that, while the lower strip, or anden, as it was called by the Spaniards, that belted round the base of the mountain, might comprehend hundreds of acres, the uppermost was only large enough to accommodate a few rows of Indian corn. *21 Some of the eminences presented such a mass of solid rock, that, after being hewn into terraces, they were obliged to be covered deep with earth, before they could serve the purpose of the husbandman. With such patient toil did the Peruvians combat the formidable obstacles presented by the face of their country! Without the use of the tools or the machinery familiar to the European, each individual could have done little; but acting in large masses, and under a common direction, they were enabled by indefatigable perseverance to achieve results, to have attempted which might have filled even the European with dismay. *22
[Footnote 21: Miller supposes that it was from these andenes that the Spaniards gave the name of Andes to the South American Cordilleras. (Memoirs of Gen. Miller, vol II. p. 219.) But the name is older than the Conquest, according to Garcilasso, who traces it to Anti, the name of a province that lay east of Cuzco. (Com. Real., Parte 1, lib. 2, cap. 11.) Anta, the word for copper, which was found abundant in certain quarters of the country, may have suggested the name of the province, if not immediately that of the mountains.]

In the same spirit of economical husbandry which redeemed the rocky sierra from the curse of sterility, they dug below the arid soil of the valleys, and sought for a stratum where some natural moisture might be found. These excavations, called by the Spaniards hoyas, or "pits," were made on a great scale, comprehending frequently more than an acre, sunk to the depth of fifteen or twenty feet, and fenced round within by a wall of adobes, or bricks baked in the sun. The bottom of the excavation, well prepared by a rich manure of the sardines, - a small fish obtained in vast quantities along the coast, - was planted with some kind of grain or vegetable. *23

The remains of these ancient excavations still excite the wonder of the modern traveller. See Stevenson, Residence in S. America, vol. I. p. 359. - Also McCulloh, Researches, p. 358.]
The Peruvian farmers were well acquainted with the different kinds of manures, and made large use of them; a circumstance rare in the rich lands of the tropics, and probably not elsewhere practised by the rude tribes of America. They made great use of guano, the valuable deposit of sea-fowl, that has attracted so much attention, of late, from the agriculturists both of Europe and of our own country, and the stimulating and nutritious properties of which the Indians perfectly appreciated. This was found in such immense quantities on many of the little islands along the coast, as to have the appearance of lofty hills, which, covered with a white saline incrustation, led the Conquerors to give them the name of the sierra nevada, or "snowy mountains."
The Incas took their usual precautions for securing the benefits of this important article to the husbandman. They assigned the small islands on the coast to the use of the respective districts which lay adjacent to them. When the island was large, it was distributed among several districts, and the boundaries for each were clearly defined. All encroachment on the rights of another was severely punished. And they secured the preservation of the fowl by penalties as stern as those by which the Norman tyrants of England protected their own game. No one was allowed to set foot on the island during the season for breeding, under pain of death; and to kill the birds at any time was punished in the like manner. *24

With this advancement in agricultural science, the Peruvians might be supposed to have had some knowledge of the plough, in such general use among the primitive nations of the eastern continent. But they had neither the iron ploughshare of the Old World, nor had they animals for draught, which, indeed, were nowhere found in the New. The instrument which they used was a strong, sharp-pointed stake, traversed by a horizontal piece, ten or twelve inches from the point, on which the ploughman might set his foot and force it into the ground. Six or eight strong men were attached by ropes to the stake, and dragged it forcibly along, - pulling together, and keeping time as they moved by chanting their national songs, in which they were accompanied by the women who followed in their train, to break up the sods with their rakes. The mellow soil offered slight resistance; and the laborer, by long practice, acquired a dexterity which enabled him to turn up the ground to the requisite depth with astonishing facility. This substitute for the plough was but a clumsy contrivance; yet it is curious as the only specimen of the kind among the American aborigines, and was perhaps not much inferior to the wooden instrument introduced in its stead by the European conquerors. *25
