Passage 1 (from Charlotte Perkins Gilman, "The Yellow Wallpaper," 1892 — public domain).
I never saw such a wallpaper in my life.
One of those sprawling flamboyant patterns committing every artistic sin.
It is dull enough to confuse the eye in following, pronounced enough to constantly irritate, and provoke study, and when you follow the lame uncertain curves for a little distance they suddenly commit suicide — plunge off at outrageous angles, destroy themselves in unheard-of contradictions.
The color is repellent, almost revolting; a smouldering unclean yellow, strangely faded by the slow-turning sunlight.
It is a dull yet lurid orange in some places, a sickly sulphur tint in others.
No wonder the children hated it! I should hate it myself if I had to live in this room long.
Passage 2 (from O. Henry, "The Gift of the Magi," 1905 — public domain).
One dollar and eighty-seven cents. That was all. And sixty cents of it was in pennies. Pennies saved one and two at a time by bulldozing the grocer and the vegetable man and the butcher until one's cheeks burned with the silent imputation of parsimony that such close dealing implied. Three times Della counted it. One dollar and eighty-seven cents. And the next day would be Christmas.
There was clearly nothing left to do but flop down on the shabby little couch and howl. So Della did it. Which instigates the moral reflection that life is made up of sobs, sniffles, and smiles, with sniffles predominating.
Passage 3 (from Sherwood Anderson, "Hands" in Winesburg, Ohio, 1919 — public domain).
Upon the half decayed veranda of a small frame house that stood near the edge of a ravine near the town of Winesburg, Ohio, a fat little old man walked nervously up and down. Across a long field that had been seeded for clover but that had produced only a dense crop of yellow mustard weeds, he could see the public highway along which went a wagon filled with berry pickers returning from the fields. The berry pickers, youths and maidens, laughed and shouted boisterously. A boy clad in a blue shirt leaped from the wagon and attempted to drag after him one of the maidens, who screamed and protested shrilly. The feet of the boy in the road kicked up a cloud of dust that floated across the face of the departing sun. Over the long field came a thin girlish voice. "Oh, you Wing Biddlebaum, comb your hair, it's falling into your eyes," commanded the voice to the man, who was bald and whose nervous little hands fidgeted about the bare white forehead as though arranging a mass of tangled locks.
