Question

how did the speaker go on to refer to day and night in relation to the white and red people​

Answer 1

There was a time when our people covered the whole land, as the waves of a wind-ruffled sea cover its shell-paved floor. But that time has long since passed away with the greatness of tribes now almost forgotten. I will not mourn over our untimely decay, nor reproach my pale-face brothers for hastening it, for we, too, may have been somewhat to blame.

"When our young men grow angry at some real or imaginary wrong, and disfigure their faces with black paint, their hearts, also, are disfigured and turn black, and then their cruelty is relentless and knows no bounds, and our old men are not able to restrain them.
