Oil! by Upton Sinclair

Dad and Bunny strapped on their cartridge belts, which went over their shoulders, and they loaded up the repeating shotguns, and set out up the little valley and over the hills. Bunny didn't really care very much about killing quail, he was sorry for the lovely black and brown birds, that had such proud and stately crests, and ran with such quick twinkling legs, and made such pretty calls at sundown. But Bunny never said anything about these ideas, because he knew Dad liked to hunt, and it was the only way you could get him away from his work, and out into the open, which the doctor said was good for his health. Dad was quick as lightning to swing his gun, and it looked as if he didn't aim at all, but apparently he did; and he never made the mistake that Bunny did, of trying to shoot at two birds at the same time. Also Dad had time to watch Bunny and teach him -- to make sure that they travelled in an even line, and didn't get turned so that one was out in front of the other's gun.

Well they tramped the hills and the valleys, and the birds rose, flying in every direction -- a whir, and a grey streak -- bang, bang -- and either they were gone, or else they were down. But you didn't run to pick them up, because there would be others, they would hide and run, and you moved on, and banged some more, until finally you gathered up all you could find, bundles of soft warm feathers, spotted with blood. Sometimes they were still alive, and you had to wring their necks, and that was the part Bunny hated.
