The Bishop and Other Stories by Anton Chekhov

The train of waggons drew up on the bank of a river on one side of a village. The sun was blazing, as it had been the day before; the air was stagnant and depressing. There were a few willows on the bank, but the shade from them did not fall on the earth, but on the water, where it was wasted; even in the shade under the waggon it was stifling and wearisome. The water, blue from the reflection of the sky in it, was alluring.

Styopka, a waggoner whom Yegorushka noticed now for the first time, a Little Russian lad of eighteen, in a long shirt without a belt, and full trousers that flapped like flags as he walked, undressed quickly, ran along the steep bank and plunged into the water. He dived three times, then swam on his back and shut his eyes in his delight. His face was smiling and wrinkled up as though he were being tickled, hurt and amused.
