when the tintinnabulation rides upon the dust...

"with the onset of summer the cross-marked sheep were herded higher into the mountains. a babbling metallic tinkling, of unknown origin and from an unknown direction, would gradually become audible. floating nearer, it enveloped the listener, giving him an odd tickling sensation in the mouth. then, in a cloud of dust, came flowing a gray, curly, tightly packed mass of sheep rubbing against each other, and the most, hollow tinkle of the bells, which delighted all of one's senses, mounted, swelled so mysteriously that the dust itself seemed to be ringing as it billowed above the moving backs of the sheep. from time to time one of them would get separated from the rest and trot past, whereupon a shaggy dog would drive it back to the flock; and behind, gently treading, walked the shepherd. then the tintinnabulation would change timber, and once more grow hollower and softer, but for a long time it would hang in the air together with the dust..."
