Having made the usual arrangements, they set out over the uninhabited region of the Huallaripa, a mountain range famous for the quantity of gold that has been taken out of it, and for the much larger quantity that remains. Having crossed this desert country, which is thirty-five leagues wide, they descended on to the sea coast llanos The whole country along the sea coast, and all other land in a hot climate, is called by the Indians yunca, which means “hot land”; and under this name of yunca they included many lands along the sea coast. The Spaniards called the country over which irrigation, from the rivers flowing from the mountains to the sea extends, valles, and this is the only part of the coast that is inhabited. For, beyond the land irrigated by the water, all the country is uninhabitable, and consists of sand, on which neither herb nor any other useful thing can grow.

At the point where these Yncas came out on the llanos is the great, fertile, and populous valley of Acari, which formerly contained more than twenty thousand Indians. The Yncas reduced them to obedience with much ease. From the valley of Acari the invaders advanced into those of Unia, Camana, Caravilli, Picta, Quilca, and others that are further on along that coast, which runs north and south for a distance of sixty leagues.
