Pontresina -- Life in the High Alps of Switzerland.The Sun Is Setting - And The Cows Are Coming Home: Around 6 p.m., as the sun sets behind the mountains, herds of cows stroll ponderously home, in long single file. Cows all wear bells round their necks, often attuned in three or four harmonious notes, and the village main street re-echoes with the sound. January 22, 1948. (Photo by Pictorial Press).
