H. Rider Haggard,
Marie: An Episode in the Life of the Late Allan Quatermain
“ I drew a deep breath, lifted the rifle, got the foresight dead upon its breast, and touched the hair-trigger. As the charge exploded I saw the aasvogel give a kind of backward twist. Next instant I heard a loud clap, and a surge of joy went through me, for I thought that the bullet had found its billet. But alas! it was not so. The clap was that of the air disturbed by the passing of the ball and the striking of this air against the stiff feathers of the wings. Anyone who has shot at great birds on the wing with a bullet will be acquainted with the sound. ”
