They contain whole nations with various political organizations; tribes of diverse races and origin, at every stage of civilization, speaking an endless number ofdifferent tongues, professing every religion of Asia, exemplifying social-customs which range from polygamy to polyandry. It scarcely seems possible that man should ever succeed incom pletely exploring this forest of peaks. Thousands of them probably reach up to 20,000 feet.
