this by his arts, traversed
the route, saw the islands, their people and riches, and, returning,
gave certain information of all to Tupac Inca.

The Inca, having this certainty, determined to go there. He caused an
immense number of _balsas_ to be constructed, in which he embarked more
than 20,000 chosen men; taking with him as captains Huaman Achachi,
Cunti Yupanqui, Quihual Tupac (all Hanan-cuzcos), Yancan Mayta, Quisu
Mayta, Cachimapaca Macus Yupanqui, Llimpita Usca Mayta (Hurin-cuzcos);
his brother Tilca Yupanqui being general of the whole fleet. Apu
Yupanqui was left in command of the army which remained on land.

Tupac Inca navigated and sailed on until he discovered the islands of
Avachumbi and Ninachumbi, and returned, bringing back with him black
people, gold, a chair of brass, and a skin and jaw bone of a horse.
These trophies were preserved in the fortress of Cuzco until the
Spaniards came. An Inca now living had charge of this skin and jaw bone
of a horse. He gave this account, and the rest who were present
corroborated it. His name is Urco Huaranca. I am particular about this
because to those who know anything of the Indies it will appear a
strange thing and difficult to believe. The duration of this expedition
undertaken by Tupac Inca was nine months, others say a year, and, as he
was so long absent, every one believed he was dead. But to deceive them
and make them think that news of Tupac Inca had come, Apu Yupanqui, his
general of the land army, made rejoicings. This was afterwards commented
upon to his disadvantage, and it was said that he rejoiced because he
was pleased that Tupac Inca Yupanqui did not appear. It cost him his
life.

These are the islands which I discovered in the South Sea on the 30th of
November, 1567, 200 and more leagues to the westward, being the great
discovery of which I gave notice to the Licentiate Governor Castro. But
Alvaro de Mendana, General of the Fleet, did not wish to occupy
them[104].

[Note 104: This story of the navigation of Tupac Inca to the islands
of Ninachumbi and Avachumbi or Hahua chumpi is told by Balboa as well as
by Sarmiento. They were no doubt two of the Galapagos Islands. _Nina
chumpi_ means fire island, and _Hahua chumpi_ outer island. See my
introduction to the _Voyages of Sarmiento_, p. xiii; and _Las Islas de
Galapagos_ by Marco Jimenes de la Espada.]

After Tupac Inca disembarked from the discovery of the islands, he
proceeded to Tumipampa, to
