Sven Hedin inherited the steel sinews of his Norse ancestors. During his many years of exploration he frequently put his physical capacities to extreme tests. He trained his constitution to stand an elevation of 19,000 feet above sea level and a temperature of 37 degrees below zero only to find himself a few months later staggering under a blistering sun in the dry river bed of a blazing desert with the thermometer at 113. He once started out with a caravan consisting of 130 beasts of burden, only to struggle weeks later to the gates of Lhasa with but eight horses and one mule. He survived ten days without food and half of that time without water, where natives succumbed to the rigors of the desert. He seemed to know every form of physical privation and touched the limits of human endurance.
When a boy he was ambitious to be the first to reach "that point where only South winds blow." He found his destiny to lie in other lands, but the distinction he achieved was no less unique. With his many volumes of accounts of exploration and discoveries to draw from, Hedin in this great autobiography has compressed between two covers the most thrilling experiences of a lifetime of adventure.
