Upton Sinclair 
Letters to Judd, an American Workingman [EPUB ebook] 

Excerpt: "Judd is an old carpenter who has done odd jobs on our place for the past ten years. Just how old he is I don’t know, but he’s pretty old; his hands are gnarled and calloused and his finger nails chewed up and broken by hammer blows; there are knotted veins in his forehead and his hair is grey and thin. But he works like a beaver, and don’t you ever hint that he should slow up-he will hoot at you, and say that he can lick any young feller with one hand. He will hitch his harness into place-he has a rupture, and wears some kind of truss-and will slide under the house to connect up a gas pipe, and come crawling out with his hair and eyes full of cobwebs, and my wife will say, "Come out of there, you old gopher." He adores her when she talks to him like that, he would lift the side of the house to please her. The two of them engage in violent arguments as to how a door ought to be hung or a tree pruned. "Nobody ever did it like that, " Judd declares-and considers that sufficient reason."
