in the plain; and for this purpose they constructed high mounds of earth across all the small vallies formed by the various rivers and torrents which descend from the mountain, that the road might be everywhere smooth and level This road was near forty feet wide, and where it crossed the sandy heights which intervene betwixt the verdant vallies of the torrents, it was marked on each side by stakes, forming palings in straight lines to prevent any one losing the way.  This road was five hundred leagues in length like that of the mountain; but the palings are now wanting in many places, the wood of which they were constructed having been used by the Spaniards for fuel during the war; but the mounds still exist across the vallies, and most of them are yet tolerably entire, by which the grandeur of the entire work may be judged of.  In his journeys to and from Quito, Huana Capac used to go by one of these roads and return by the other; and during his whole journey his subjects used to strew the way with branches and flowers of the richest perfume.

Besides the two great roads already mentioned, Huana Capac ordered to be built on the mountain road a number of large palaces, at the distance of a days journey from each other, having a prodigious number of apartments, sufficient to lodge his own personal suite and all his army.  Such were likewise built along the road in the plain, but not so numerous or so near each other as on the mountain road, as these palaces of the plain had all to be placed on the sides of the rivers for convenience and the procurement of provisions and other necessaries; so that they were in some places eight or ten leagues distant from each other, and in other places fifteen or twenty leagues.  These buildings were named tambos, and the neighbouring Indians were bound to furnish each of these with provisions and every thing else that might be wanted for the royal armies; insomuch that in each of these tambos, in case of necessity, clothing and arms could be had for twenty or thirty thousand men.  Huana Capac was always escorted by a considerable body of soldiers, armed with lances, halberts, maces, and battle axes, made of silver or copper, and some of them even of gold.

In their armies, besides these arms, the Peruvians used slings, and javelins having their points hardened in the fire.  On such parts of their rivers as furnished materials for the purpose, they built wooden bridges; and where timber could not be had, they stretched across the stream two large cables made of a plant named maguey, forming a kind of net work between these of smaller ropes and masts, strong enough to answer the purpose of a bridge.  In this manner they constructed bridges of a surprizing magnitude; some of them being thirty yards broad and four hundred yards long[32].  In such places as did not admit of the construction of bridges, they passed over rivers by means of a cable or thick rope extended from side to side, on which they hung a large basket, which was drawn over by means of a smaller rope.  All these bridges were kept in repair by the inhabitants of the districts in which they stood.
