The South American Indians were in a measure agriculturists, and had many things under culture of which the origin is unknown. The potato was so cultivated, and was common in Indian gardens from Chili to New Grenada. It is remarkable that none of the plants grown in this way can be traced to Asia, and if the Indians came from Asia and made colonies here, they did not bring these things with them. The articles in question are evidently of American origin, but of which the originals are lost.
