They are true Portoricans and love to call themselves Borinqueños, from the aboriginal
name Borinquen- of the island. They form the overwhelmingly leading political factor, though there are two other races represented
in great numbers. The one of most interest is the Indio,
or that of the descendants or the inhabitants found on the island at its discovery and settlement. They form the great mass
of the country laborers over the island, especially in the Centre and the northeastern section. They have much of the serious
appearance of the North American Indian, with his high cheek bones, but their color is less red and more swarthy. They are inclined to keep to themselves and specially not to mingle with the blacks, but with the
Spanish they have mingled freely with the Spaniards. Tradition gives them the right to the soil and they are said to still
observe certain clannish and fraternal rites inherited from their ancestors. They know little of education and are generally merely day laborers.
