AN EXPLORER'S ADVENTURES IN TIBET

Tibet was a forbidden land. That is why I went there.
This strange country, cold and barren, lies on a high tableland in the heart of Asia. The average height of this desolate tableland—some 15,000 feet above sea-level—is higher than the highest mountains of Europe. People are right when they call it the "roof of the world." Nothing, or next to nothing, grows on that high plateau, except poor shrubs and grass in the lower valleys. The natives live on food imported from neighboring countries. They obtain this by giving in exchange wool, borax, iron, and gold.
High mountain ranges bound the Tibetan plateau on all sides. The highest is the Himahlya range to the south, the loftiest mountain range on earth. From the south it is only possible to enter Tibet with an expedition in summer, when the mountain passes are not entirely blocked by snow.

At the time of my visit the law of Tibet was that no stranger should be allowed to enter the country. The Tibetan frontier was closely guarded by soldiers.
