The royal road of the Yncas goes from this province of Huamachuco to the province of the Conchucos, a distance of two short days' journey, and half-way there were buildings and store-houses prepared for the reception of the Kings when they travelled this way; for it was their custom, when they visited any part of this kingdom, to travel in great state, and to be served with all things appertaining to their rank; and it is said that, except on occasions when their service required it, the Yncas did not travel more than four leagues each day. In order that there might be sufficient food to support their retinue, there were buildings and store-houses at every four leagues, with great abundance of all the provisions that the surrounding districts could supply. The lieutenants and overseers who resided at the chief stations in the provinces took special care that the natives kept these tampus well provisioned. And that one might not have to contribute more of this tribute than another, accounts were kept by a kind of knots, called quipu, which were understood, and thus there was no fraud. Certainly, although to us it may appear confusing and obscure, this is a good way of keeping accounts, as I will more fully show in the second part. Between Huamachuco and the Conchucos, although it was two days' journey, there were store-houses and tampus in two places on the road, which is always kept very clean.
